A stunning image captured by a Nasa satellite reveals the impact that ships passing through the Atlantic Ocean have on the clouds above.
The image shows a patchwork of bright, criss-crossing cloud trails off the coast of Portugal and Spain, known as ship tracks.
Ship tracks form when water vapour condenses around tiny particles of pollution that ships emit as exhausts.
These incredible clouds typically form in areas where low-lying stratus and cumulus clouds are present.
In a blog about the image, a spokesperson for Nasa said:“Some of the pollution particles generated by ships (especially sulfates) are soluble in water and serve as the seeds around which cloud droplets form.
“Clouds infused with ship exhaust have more and smaller droplets than unpolluted clouds.
“As a result, the light hitting the polluted clouds scatters in many directions, making them appear brighter and thicker than unpolluted marine clouds, which are typically seeded by larger, naturally occurring particles such as sea salt.”
The image was taken by the Moderate Resolution Imaging Spectroradiometer on board Nasa’s Aqua satellite on January 16.
While the ship tracks may not look too long in the image, in reality, some stretch hundreds of kilometres from end to end.
The narrow ends of the clouds are youngest, while the broader, wavier ends are older.
=====================================================
The above gives an inkling as to what happens when volcanic ashes and an increasing amount of meteoritic/cometary dust settle down... which may be the omitted, generating factor for persistent contrails; beside pollution.

Re: Dust Particles Influence On The Weather AND Earth's Climate
Fascinating......I've recently come across some compelling research that indicates that water vapour when factored into the false climate models illustrates almost ALL of the "global warming" a missing link so to say. These vapours can be produced by solar and cosmic radiation interacting with our atmosphere.
Nearly 20 years ago there was a documentary on a PBS type channel (TV Ontario actually with David Suzuki narrating I believe) that illustrated how planktons would rush to the surface and release something like a spore? or particles? (I cannot recall) in order to force a thunderstorm that would produce conditions so they could gorge and feed. Noting phytoplantkons exist in the hundreds of trillions........of course whales would come and eat them :)
If cargo ships switched to all electric the equivalent Annual output of pollution from the USA would disappear.
Here is one of these ghost ships prototypes ( I don;t expect they go anywhere near the Somali pirates)
The Dutch company Port-Liner is building two giant all-electric barges dubbed the ‘Tesla ships‘. The company announced that the vessels will be ready by this autumn and will be inaugurated by sailing the Wilhelmina canal in the Netherlands.
The 100 million-euro project supported by a €7m subsidy from the European Union is expected to have a significant impact on local transport between the ports of Amsterdam, Antwerp, and Rotterdam.
Chief executive of Port-Liner Ton van Meegen told The Loadstar:“There are some 7,300 inland vessels across Europe and more than 5,000 of those are owned by entrepreneurs in Belgium and the Netherlands. We can build upwards of 500 a year, but at that rate it would take some 50 years to get the industry operating on green energy.”
The battery-powered barges – pictured above – are capable of carrying 280 containers.
The first 6 barges are expected to remove 23,000 trucks from the roads annually in the Netherlands and replace them with zero-emission transport.

I found something about the Plankton
Clouds From Plankton Blooms Control Weather
Russ George / July 14, 2014 / Comments Off on Clouds From Plankton Blooms Control Weather / Get Your Geek On, Good News For The Planet
Ocean plankton produce clouds as they thrive
Ocean plankton is the largest natural factor of this blue planet when it comes to managing CO2 (and sunlight via clouds.) These micro plants of the world’s ocean convert CO2 from its ocean acidifying form and global warming form into more ocean plants, phytoplankton. They are just being plants like any other which complete this miracle through photosynthesis. But very few people know that ocean plants also control the amount of sunlight that falls on the ocean by producing a chemical known as DMS that is a powerful cloud forming compound.

Re: Dust Particles Influence On The Weather AND Earth's Climate
Full journal article
Abstract: The major source of cloud-condensation nuclei (CCN) over the oceans appears to he dimethylsulphide, which is produced by planktonic algae in sea water and oxidizes in the atmosphere to form a sulphate aerosol. Because the reflectance (albedo) of clouds (and thus the Earth’s radiation budget) is sensitive to CCN density, biological regulation of the climate is possible through the effects of temperature and sunlight on phytoplankton population and dimethylsulphide production. To counteract the warming due to doubling of atmospheric CO2, an approximate doubling of CCN would he needed.

Yeah... clouds of strange origins:
Spectacular polar stratospheric clouds captured over Peru (PHOTOS)
Sott.net
Sun, 28 Jan 2018 09:27 UTC
Stunning polar stratospheric clouds were captured by David Alvarado over Lamas, in the region of San Martín, Peru on January 18, 2018.
Polar stratospheric clouds, also known as nacreous clouds (or mother of pearl, due to its iridescence), are clouds in the winter polar stratosphere at altitudes of 15,000-25,000 meters (49,000-82,000 ft). Usually the clouds only form over the poles during winter because the air in the upper stratosphere needs to be at least -78C.
These images were posted on Red Climática Mundial (Global Climate Network).
This 'rare' phenomena is becoming increasingly common: Though beautiful, these clouds are likely an indication of a cooling atmosphere, due to dust loading from increased comet and volcanic activity.

Re: Dust Particles Influence On The Weather AND Earth's Climate
The cosmic fuse to all sorts of dust particles generation:
Early humans witnessed global cooling, warming, and massive fires from comet debris impacts says major study
Anthony Watts Watts Up With That
Sat, 03 Feb 2018 11:15 UTC
New research suggests toward end of Ice Age, human beings witnessed fires larger than dinosaur killers
On a ho-hum day some 12,800 years ago, the Earth had emerged from another ice age. Things were warming up, and the glaciers had retreated.
Out of nowhere, the sky was lit with fireballs. This was followed by shock waves.
Fires rushed across the landscape, and dust clogged the sky, cutting off the sunlight. As the climate rapidly cooled, plants died, food sources were snuffed out, and the glaciers advanced again. Ocean currents shifted, setting the climate into a colder, almost "ice age" state that lasted an additional thousand years.
Finally, the climate began to warm again, and people again emerged into a world with fewer large animals and a human culture in North America that left behind completely different kinds of spear points.
This is the story supported by a massive study of geochemical and isotopic markers just published in the Journal of Geology.
The results are so massive that the study had to be split into two papers.
"Extraordinary Biomass-Burning Episode and Impact Winter Triggered by the Younger Dryas Cosmic Impact ~12,800 Years Ago" is divided into "Part I: Ice Cores and Glaciers" and "Part 2: Lake, Marine, and Terrestrial Sediments."
The paper's 24 authors include KU Emeritus Professor of Physics & Astronomy Adrian Melott and Professor Brian Thomas, a 2005 doctoral graduate from KU, now at Washburn University.
"The work includes measurements made at more than 170 different sites across the world," Melott said.
https://www.sott.net/image/s22/44894...nline_high.jpg
The solid line defines the current known limits of the Younger Dryas Boundary field of cosmic-impact proxies, spanning 50 million square kilometers. Again, used to illustrate this story, not part of the original press release.
The KU researcher and his colleagues believe the data suggests the disaster was touched off when Earth collided with fragments of a disintegrating comet that was roughly 62 miles in diameter - the remnants of which persist within our solar system to this day. "The hypothesis is that a large comet fragmented and the chunks impacted the Earth, causing this disaster," said Melott.
"A number of different chemical signatures - carbon dioxide, nitrate, ammonia and others - all seem to indicate that an astonishing 10 percent of the Earth's land surface, or about 10 million square kilometers, was consumed by fires."
According to Melott, analysis of pollen suggests pine forests were probably burned off to be replaced by poplar, which is a species that colonizes cleared areas.
Indeed, the authors posit the cosmic impact could have touched off the Younger Dryas cool episode, biomass burning, late Pleistocene extinctions of larger species and "human cultural shifts and population declines." "Computations suggest that the impact would have depleted the ozone layer, causing increases in skin cancer and other negative health effects," Melott said.
"The impact hypothesis is still a hypothesis, but this study provides a massive amount of evidence, which we argue can only be all explained by a major cosmic impact."
The study: http://www.journals.uchicago.edu/doi/10.1086/695703 Extraordinary Biomass-Burning Episode and Impact Winter Triggered by the Younger Dryas Cosmic Impact ∼12,800 Years Ago. 1. Ice Cores and Glaciers
Abstract
The Younger Dryas boundary (YDB) cosmic-impact hypothesis is based on considerable evidence that Earth collided with fragments of a disintegrating ≥100-km-diameter comet, the remnants of which persist within the inner solar system ∼12,800 y later.
Evidence suggests that the YDB cosmic impact triggered an "impact winter" and the subsequent Younger Dryas (YD) climate episode, biomass burning, late Pleistocene megafaunal extinctions, and human cultural shifts and population declines. The cosmic impact deposited anomalously high concentrations of platinum over much of the Northern Hemisphere, as recorded at 26 YDB sites at the YD onset, including the Greenland Ice Sheet Project 2 ice core, in which platinum deposition spans ∼21 y (∼12,836-12,815 cal BP).
The YD onset also exhibits increased dust concentrations, synchronous with the onset of a remarkably high peak in ammonium, a biomass-burning aerosol. In four ice-core sequences from Greenland, Antarctica, and Russia, similar anomalous peaks in other combustion aerosols occur, including nitrate, oxalate, acetate, and formate, reflecting one of the largest biomass-burning episodes in more than 120,000 y.
In support of widespread wildfires, the perturbations in CO2 records from Taylor Glacier, Antarctica, suggest that biomass burning at the YD onset may have consumed ∼10 million km2, or ∼9% of Earth's terrestrial biomass.
The ice record is consistent with YDB impact theory that extensive impact-related biomass burning triggered the abrupt onset of an impact winter, which led, through climatic feedbacks, to the anomalous YD climate episode.

Re: Dust Particles Influence On The Weather AND Earth's Climate
Volcanic eruptions, epics, pagan gods and the shift towards monotheism in Middle Ages Iceland
Laura Geggel Live Science
Tue, 20 Mar 2018 09:06 UTC
A series of Earth-shattering volcanic eruptions in Iceland during the Middle Ages may have spurred the people living there to turn away from their pagan gods and convert to Christianity, a new study finds.
The discovery came about thanks to precise dating of the volcanic eruptions, which spewed lava about two generations before the Icelandic people changed religions.
But why would volcanic eruptions turn people toward monotheism? The answer has to do with the "Vǫluspá," a prominent medieval poem that predicted a fiery eruption would help lead to the downfall of the pagan gods, the researchers said. [Cracking Codices: 10 of the Most Mysterious Ancient Manuscripts]
New, volcanic land
Historians have long known that the Vikings and Celts settled Iceland in about A.D. 874, but they were less certain about the date of the Eldgjá lava flood, the largest eruption to hit Iceland in the past few millennia. Knowing this date is crucial, because it can tell scientists whether the eruption - a colossal event that unleashed about 4.8 cubic miles (20 cubic kilometers) of lava [ash?] onto Greenland - impacted the settlement there, the researchers said.
To investigate, the researchers examined ice core records. Their results showed that the eruption took place less than 100 years after people settled the island. The volcano began gushing lava in the spring of A.D. 939 and lasted, at least episodically, until the autumn of 940, the researchers said. "This places the eruption squarely within the experience of the first two or three generations of Iceland's settlers," study lead researcher Clive Oppenheimer, a professor of volcanology at the University of Cambridge, in England, said in a statement.
"Some of the first wave of migrants to Iceland, brought over as children, may well have witnessed the eruption."
The finding matches medieval chronicles from Ireland, Germany and Italy that noted the spread of a haze in 939. Moreover, the tree-ring data revealed that in A.D. 940, the Northern Hemisphere had one of its coldest summers in the previous 1,500 years - a cold shift consistent with the release of large amounts of volcanic sulfur into the atmosphere, the researchers said. "In 940, summer cooling was most pronounced in Central Europe, Scandinavia, the Canadian Rockies, Alaska and Central Asia, with summer average temperatures 2 degrees Celsius [3.6 degrees Fahrenheit] lower," co-researcher Markus Stoffel, a professor in the Department of Earth Sciences at the University of Geneva in Switzerland, said in the statement.
Suffering followed, with hard winters and drought in the spring and summer. Locusts invaded, and livestock died. "Famine did not set in everywhere, but in the early 940s, we read of starvation and vast mortality in parts of Germany, Iraq and China," said study co-researcher Tim Newfield, an environmental historian at Georgetown University, in Washington, D.C.
However, no texts from that period survive from Iceland, the volcano's homeland.
A mere two generations after the Eldgjá eruption, in about A.D. 1000, the people of Iceland formally converted to Christianity. And it likely had to do with the "Vǫluspá," the researchers said. [The 11 Biggest Volcanic Eruptions in History]
Apocalyptic poem
The "Vǫluspá" was written after the eruptions, in about A.D. 961. It describes how an eruption and meteorological events would mark the end of the pagan gods, who would be replaced by one, singular god, the researchers said.
Part of the poem explains how "the sun starts to turn black, land sinks into sea; the bright stars scatter from the sky ... flame flies high against heaven itself," according to a translation.
Considering Eldgjá's eruptions date to before the poem was written, Icelanders who experienced the fiery spectacle likely looked back at the events and wrote the poem, "with the purpose of stimulating Iceland's Christianization over the latter half of the 10th century," the researchers wrote in the study, published online today (March 19) in the journal Climate Change.

The effect of volcanoes on climate and climate on volcanoes
Andy May WUWT

In this photo provided by the U.S. Geological Survey, red ash rises from the Puu Oo vent on Hawaii's Kilauea Volcano after a magnitude-5.0 earthquake struck the Big Island, Thursday, May 3, 2018 in Hawaii Volcanoes National Park. © volcanoes.usgs.gov
The relationship between volcanoes and climate is a very complex one. From reading the media one gets the impression that they are some sort of climatic wild card. They are used to explain the cooling after the Pinatubo eruption, or the Little Ice Age cooling as a detriment to the solar hypothesis. But they are also used to explain the warming leading to mass extinctions in the distant past.
To be able to fulfill such a dual role, scientists take advantage of the different gas emissions from volcanoes. About 50-90 % of the gas emitted by volcanoes is water vapor. The rest is highly variable from one volcano to another, but CO2 can be 1-40 %, SO2 1-25 %, H2S 1-10 %, and HCl 1-10 %, plus a lot of other minor gases. H2S gets quickly oxidized to SO2.
If we want to concentrate on the cooling produced by volcanoes we look at SO2 (+H2S). Due to silent degassing, nobody knows how much SO2 volcanoes are producing, and the estimates vary wildly, but their contribution is very significant. SO2 placed in the troposphere gets converted to sulfate and coalesces into aerosols that affect cloud condensation and get precipitated as acid rain in a relatively short time. SO2 also reaches the stratosphere mainly during explosive eruptions that take place about every two years, but also from rising tropospheric SO2. Most of the stratospheric SO2 is of volcanic origin. In a period of weeks to months stratospheric SO2 gets converted to sulfate, dehydrating the stratosphere and building a sulfate peak in about 3 months after the eruption, that produces a stratospheric aerosol layer enhancement that lasts about 4 years.
The better known one is to scatter incoming solar radiation producing surface cooling. But they also absorb near IR (Infrared radiation) and LWR (longwave infrared radiation, incoming and outgoing) producing stratospheric heating, affecting atmospheric circulation and leading to warm winters in the Northern Hemisphere (NH) in the 1-2 years after a stratospheric eruption. The third effect is a very effective destruction of ozone due to altered chemistry and perturbed heating rates. The drop in the ozone level affects stratospheric climate leading to widespread atmospheric changes and to an increase in solar UV (ultraviolet) radiation reaching the surface.
To complicate things, the climatic effects of volcanoes depend a lot not only on their SO2 stratospheric injection, but also on the latitude of the volcano and the time of the year. These factors have a significant effect on the dispersal of the cloud. Thus, some volcanoes have a global effect while others only a hemispheric one, or no effect at all, like the Mt. St. Helen's eruption of 1980, a strong volcanic eruption with no climatic effect.
When scientists want to concentrate on the warming produced by volcanoes, they look at CO2. Currently CO2 emissions from volcanoes are too small, about 1% of anthropogenic emissions. But, in the distant past the amount of CO2 produced by a much higher level of volcanic activity, particularly by Large Igneous Provinces (LIP), might have been very considerable. Since mass extinctions, from the past in some cases, correlate well with LIP, there is a lively debate on whether SO2 and cooling, or CO2 and warming, caused the extinction, with the latter one being the most popular hypothesis today.
Volcanic activity and the Little Ice Age
The available evidence from El Chinchon and Pinatubo eruptions only supports a short-term effect from volcanoes on temperatures, lasting at most a few years. Based on this evidence volcanic eruptions affect weather, not climate, very much like strong El Niño events, but opposite. In fact an El Niño-like condition develops in the first year after large tropical eruptions, followed by a stronger La Niña-like condition in the second year (Sun et al., 2018). The La Niña condition recharges subsurface ocean temperatures, contributing to a rebound in temperatures once the volcanic stratospheric effect ends, around the fourth year.

Thin lines represent 3 Northern and 4 Central sites to assess spatial and temporal variability. Source: Esper et al., 2013.
This evidence makes it difficult to explain the LIA (the Little Ice Age) in terms of volcanic activity, and therefore weakens the CO2-hypothesis. The main alternative to the volcanic hypothesis is that the LIA was caused by a reduction in solar activity, but if lower solar activity is more important in the LIA cooling, then increasing solar activity is likely to be more important in modern global warming.
Defenders of a volcanic-LIA use models to support a much longer effect by larger eruptions that took place during the LIA, like the Tambora eruption of 1815, by clusters of eruptions, and by a proposed long-term oceanic effect from eruptions. While these explanations are possible, there is no evidence supporting them. Tree-ring analysis shows a similar weather effect for LIA volcanoes (figure 2). The solar-LIA hypothesis has the problem that the cooling started before some of the solar grand minima started and that the cold periods don't exactly match the low solar activity periods.
Most scientists, however, accept that the LIA was probably caused by a combination of solar and volcanic causes and the discussion is about which cause was more important. A clear possibility is that low solar activity prevented the recovery from volcanic cooling, prolonging its effects and acting synergistically to produce a bigger combined cooling.
However more information can be gained by studying the effect that climate change has on volcanic activity.
The effect of climate on volcanoes
The idea that volcanoes affected climate by causing cooling on a temporal scale of less than a decade was an old one, already reported in 1940, and in the early 1970's there was speculation that volcanoes could be a cause for glaciations. However, in the mid-1970's J. Roger Bray, the discoverer of the 2500-year solar-climate cycle (wrongly named Hallstatt), made the observation that moving to temporal scales of centuries to millions of years the correlation between "volcanic pulses" and glacial advances was the opposite. Some glacial advances appeared to precede by a few centuries the "volcanic pulses" that were supposed to be their cause, and over the past 2 million years major ice-sheet expansions had lagged behind "volcanic pulses" by up to 10,000 years (Bray, 1977).
By the late-1970's it was clear that the effect of volcanoes on climate was limited. As Rampino et al. reported in 1979: "The eruption of Tambora in 1815, one of the largest eruptions during the past few thousand years, is associated with a hemispheric temperature decrease of only 0.5° to 1°C for 2 to 3 years. In this case, average global temperatures had already been decreasing since 1810 and then rose again in the 1820's."
Rampino et al. (1979) confirmed one of Bray's observation that major historical eruptions associated with cooling were taking place after decadal length temperature decreases had been initiated, so they asked if rapid climate change could cause volcanic eruptions, by means of stress changes on the earth's crust, through loading and unloading of ice and water masses and through axial and spin-rate changes.
This question was left unanswered and forgotten once scientific focus changed from cooling to warming in the 1980's. However, through better data collection the question reemerged at the turn of the century. Zielinski et al. published in 1996 the GISP2 ice-core record of 110,000 years of explosive volcanism (figure 3), showing that the transitions between colder periods (stadials) and warmer periods (interstadials) displayed increased volcanism. The following year McGuire et al. published a correlation between sea-level changes and the frequency of explosive volcanism in the Mediterranean. And in 1999 Glazner et al. published under the suggestive title "Fire or ice," that the anti-correlation between volcanism and glaciation extended for the past 800,000 years in the Californian volcanoes, located 300 km from the sea. This was also confirmed for continental volcanism in France and Germany by Nowell et al. in 2006.
https://www.sott.net/image/s23/46714...eeffectof3.png
Figure 3. GISP2 ice core volcanic SO2 (red), total SO2 (blue), and temperature (black, from δ18O proxy), for the past 50,000 years. Non-volcanic SO2 correlates with other sea salt ions. This graph demonstrates that the LIA cannot be due to volcanic activity, as the highest volcanic activity, several times higher than during the LIA, is associated with the strongest warming in 50,000 years, and the warmest period of the Holocene.
Then research turned to the mechanisms. Jellinek et al. showed in 2004 that Californian volcanoes were responding to ice changes in the obliquity (41-kyr) frequency with a time lag, related to glacial unloading, that was of a few kyr for silicic volcanism but of ~ 10-kyr for basaltic volcanism. They advanced the hypothesis that the decrease in pressure from ice melting stimulated dike formation leading to more explosive volcanism. But this is not the only hypothesis. Volcanism is terribly complicated, and caldera-forming volcanoes from the glaciated arc of Kamchatka seem to respond to glacial loading and show peak activity during glacial maxima (Geyer and Bindeman, 2011).
Kutterolf et al. conducted in 2013 the most comprehensive analysis to date of the temporal frequency of volcanism in the Ring of Fire, where most of the world's largest volcanic eruptions have occurred in the recent past. They built an extensive dataset of 408 tephra (volcanic ejecta) layer dates for the past million years from multiple coring sites down-stratospheric-wind from volcanic areas along the Pacific Ring of Fire. Frequency analysis of volcanic eruption activity shows a significant peak at the 41-kyr period with non-significant peaks also at the 23-, 82-, and 100-kyr Milankovitch frequencies (figure 4). The 41-kyr volcanic frequency peak coincides in period with the δ18O rate from benthic cores. Since changes in δ18O rate are anti-phased with obliquity, volcanism peaks roughly when the rate of change of δ18O is most negative, i.e. ~ 4 kyr after the greatest rate of sea-level rise and ice volume decline (figure 4).

Ice cores (volcanic sulfate deposition) and volcanic (tephra layers) datasets independently show that the highest level of volcanic activity for the past 100,000 years took place between 13 and 7 kyr BP, with a rate 2-6 times above background level (figure 5c). Part of the lag with respect to the start of the deglaciation at ~ 18 kyr might be due to the melting starting at the Eastern Laurentide and Antarctic ice sheets that do not affect volcanic regions. After 7 kyr BP, once the ice sheets melted, volcanic activity has declined and has returned to background glacial-comparable levels.
Huybers and Langmuir (2009) have analyzed CO2 output by volcanoes at deglaciation, considering that the increase in subaerial volcanism due to melting must have been compensated in part by a decrease in non-ridge associated submarine volcanism due to the increasing load of sea-level rise. Their modeling indicates that half of the CO2 increase (~ 40 ppm) during deglaciation is due to the volcanic response to climate change, constituting an important feedback factor to glacial termination.

Discussion and conclusions
The Holocene Climatic Optimum, the warmest period of our interglacial, showed a level of volcanic activity 2-4 times higher than the Little Ice Age, the coldest period of our interglacial. Therefore, it is impossible that the LIA may have been caused mainly by volcanic activity.
Volcanic activity has no detectable climatic effect in the Pleistocene. Volcanic eruptions affect weather (a few years), not climate, and their only possible climatic effect is a hypothetical (but reasonable) feedback effect at glacial terminations through their significant contribution to CO2 increase.
However, climate change has a strong effect on volcanism. The effect of obliquity-linked ice unloading is very clear. Due to the asymmetric nature of ice changes, as melting is very rapid, but ice build-up is very slow, the effect of ice unloading has been well established, but that of ice loading has not. Anecdotal evidence since the 1970's suggests that ice loading might also increase volcanic activity, as eruptions have been observed after decades-long cooling periods, however, the evidence for this is not significant.

The Medieval Warm Period peaked ~ 1100 AD. By the time the Samalas eruption of 1257 took place, the world had been on a cooling trend for a century and a half (figure 6). I place the start of the LIA at 1258 as it makes for a nice boundary. 1258 was the first taste of the coming climate misery that the LIA brought, characterized by crop failure, famine, epidemics, and social disruption like the appearance of the bizarre flagellant movement in 1260 (Stothers, 2000). See figure 7.
The Holocene Climatic Optimum and the Little Ice Age are not differentiated by their CO2 levels, that were about the same, while volcanic activity was much higher during the HCO. What separates them is their different solar irradiation from both orbital changes and solar activity. The solar-LIA remains the only hypothesis supported by evidence, even if we do not understand well the climatic response to reduced solar activity.
A final corollary is that the strong reduction in the continental cryosphere observed during the present global warming is likely to be paid down the road in the form of increased volcanic (and seismic) activity, due to ice unloading. Whatever its cause, the potential for a hazardous geospheric response to climate change is real (McGuire, 2010).

Re: Dust Particles Influence On The Weather AND Earth's Climate
Noctilucent cloud season over the Arctic began May 27th 2018
Space Weather
Thu, 31 May 2018 16:17 UTC
NASA's Aeronomy of Ice in the Mesosphere (AIM) spacecraft has spotted its first noctilucent clouds (NLCs) of the 2018 season. They are the electric-blue puffs circled in this image of the Arctic taken by AIM's CIPS instrument on May 27th:
"The summer season for noctilucent clouds has begun," says Cora Randall, AIM science team member at the University of Colorado.
"We spotted the first hint of NLCs in our data on May 23rd; now they are brightening rapidly."
NLCs are Earth's highest clouds. Seeded by meteoroids, they float at the edge of space more than 80 km above the planet's surface. The clouds form when summertime wisps of water vapor waft up and crystallize around specks of meteor smoke.
Previous data from AIM have shown that NLCs are like a great "geophysical light bulb." They turn on every year in late spring, reaching almost full intensity over a period of 5 to 10 days. This means observers on the ground could begin to see them not long after AIM does.
Early-season NLCs are usually faint and always found in high latitude places such as Canada, the British isles, Siberia and Scandinavia. To people in those areas, we offer the following observing tips: Look west 30+ minutes after sunset when the sun has dipped 6o or more below the horizon. If you see luminous blue-white tendrils spreading across the sky, you may have spotted a noctilucent cloud.
SOTT Comment:
Interestingly, it's the 31st of May, but June 15th 2017 Space Weather reported in The mystery of absent noctilucent clouds: During the first two weeks of June 2017, Spaceweather.com received zero images of NLCs - something that hasn't happened in nearly 20 years.
Where did they go?
Researchers have just figured it out: There's been a "heat wave" in the polar mesosphere, a region in Earth's upper atmosphere where NLCs form. Relatively warm temperatures have wiped out the clouds.
So with the unsettling rise in fireballs, one would think the two would increase in tandem, and yet, evidently, our atmosphere isn't behaving as is expected. And perhaps when this year's peak occurs will provide more data on just what's going on up there:

Strange skies: Red Sprites in Oklahoma, aurora Steve in Canada, iridescent clouds in Illinois and noctilucent clouds in Denmark
Space Weather
Sat, 02 Jun 2018 12:12 UTC
The epicentre of Sprite Alley
Oklahoma is a good place to see sprites. "I photograph them often," says Paul Smith of Edmond OK. "Here are some examples from May 30th flashing above fast-moving storms in the Oklahoma panhandle."
"Venus is the bright 'star' just behind the windmill," he adds.
Oklahoma is the epicenter of a region that we call "Sprite Alley," a corridor stretching across the US Great Plains where intense thunderstorms produce lots of upward directed lightning--a.k.a. "sprites."
"I have been recording sprites since last summer when I accidentally caught a few during the Perseid meteor shower," says Smith. "I now have a couple of hundred events on camera and I am out almost every night there are storms in my vicinity."
The blue pushpin in the satellite weather map, below, shows Smith's location. The blue arrow points to the storm cell that produced the sprites.
People have been seeing sprites since at least the 19th century, but those early reports were often met with skepticism. Sprites entered the mainstream in 1989 when researchers from the University of Minnesota finally captured them on film. Subsequent video footage from the space shuttle cemented their status as an authentic physical phenomenon.
In recent years, citizen scientists have been photographing sprites in record numbers. But why? It could be a result of raised awareness. More photographers know about sprites, so naturally more sprite photos are taken. There might also be a real increase in sprite activity. Some researchers think that sprites are linked to cosmic rays: Subatomic particles from deep space strike the top of Earth's atmosphere, producing secondary electrons that trigger the upward bolts. Indeed, cosmic rays are now intensifying due to the decline of the solar cycle.SOTT Comment:
The latter explanation is more likely, in tandem with a variety of other changes:
Photographer captures yet another photo of 'rare' red sprites - in skies above Oklahoma
It all adds up to more sprites over Oklahoma. More examples may be found on Paul Smith's Facebook page.
Steve spotted in Canada
Rare video of aurora phenomenon "Steve" - formally discovered in 2017
On May 31st, as Earth was entering a stream of high-speed solar wind, hot currents of plasma began to flow through the upper atmosphere over North America. When this happens, STEVE appears. Matthew Wheeler saw the purple ribbon of light from Robson Valley, British Columbia:
"It was visible to the naked eye despite bright moonlight," says Wheeler, who, on darker nights, has taken some incredible videos of the STEVE phenomenon.
This particular stream of solar wind has a knack for summoning STEVE. One solar rotation ago, in early May, the same stream lashed Earth's magnetic field. STEVE was then sighted not only in Canada (its usual habitat) but also in multiple US states. Bright moonlight this time is making the mysterious ribbon more difficult to see, and will probably reduce the number of sightings.
Noctilucent clouds seen from the ground
Only a few days after NASA's AIM spacecraft began to see noctilucent clouds (NLCs) forming over Earth's northern hemisphere, people on the ground are beginning to see them, too. "They are back!" reports Ruslan Merzlyakov of Hjørring, Denmark. "I saw the NLCs during the early hours of May 31st." In this picture, they are silvery ripples beaming through the orange glow of sunrise:
Early-season sightings of NLCs are always like this--faint and silvery, with a rippling structure that distinguishes them from ordinary clouds. They may not remain faint for long. Previous data from AIM have shown that NLCs are like a great "geophysical light bulb." They turn on every year in late spring, reaching almost full intensity over a period of 5 to 10 days. Soon the silvery ripples Merzlyakov spotted should intensify and spread, forming electric-blue waves that glow deep into the night.
Noctilucent cloud season over the Arctic began May 27th 2018
What are NLCs? You can think of them as frosted meteoroids. Noctilucent clouds form when summertime wisps of water vapor waft up to the top of Earth's atmosphere and crystallize around specks of meteor smoke. The resulting swarms of tiny ice crystals glow electric blue when struck by high altitude sunlight.
Colorful clouds pile above Alberto
Yesterday, May 30th, tropical depression Alberto was spending the last of its strength over Illinois when Chris Moore in the town of Streator looked up at the sky."I caught these spectacular rainbow-colored rings swirling around a cloud bank on the western edge of the storm," he says.
"The setting sun lit up the wispy clouds from behind."
These are pileus clouds, and while they may resemble rainbows, they form in a completely different way. To make a pileus cloud, a cumulus cloud must first boil upward, pushing layers of moist air above it where the layers cool and condense to form cloud caps ('pileus'). Because pileus clouds form very quickly, their internal water droplets tend to be all the same size--the perfect condition for iridescence. Uniform droplets diffract passing sunlight into vivid pastel hues.
Normally pileus clouds appear on warm summer afternoons when the landscape is festooned with rising cumulous towers. In this case, however, Alberto created the conditions for a late-spring display.
SOTT Comment: It wasn't so long ago that these strange sights in the sky were considered a rarity, now they're being documented daily.

Changing atmosphere: Footage of Russian rocket flyover lights up social media
RT
Sun, 17 Jun 2018 08:02 UTC
A scheduled launch of Russia's Soyuz rocket with a satellite aboard turned into quite an event in Russia after pictures of it heading into space baffled the whole country.
People across Russia took to social media to post dazzling pictures and videos featuring a mysterious object flying over them in the night to Sunday. Searching for an explanation, some said it could have been a UFO. Others said the white oval object leaving a massive trail could be a sign that Russia's state of the art ICBM Topol-M had been launched.
However, alien-seekers were left disappointed, as it turned out to be a Russian Soyuz 2.1-b rocket, which was launched at 12:46am Moscow time (21:46 GMT) from the Plesetsk test launch site. Several hours later, the carrier rocket's Fregat booster put the Glonass-M navigational satellite into orbit. The satellite will join the group of Russia's Global Navigation Satellite System (GLONASS), which currently has a total of 25 objects, one of which is currently undergoing flight tests.
Those living close to the site apparently knew what was going on and just posted pictures, commenting on the amazing view. The flyover was seen from various corners of the country, from Arkhangelsk Region to Moscow.

According to that graph, it appears that a dust cloud precedes a jump in Polar temperatures... a considerably significant jump... anyone heard of that anywhere???
If correct and accurate, that graph smashes to pieces the idea of "nuclear winters" following heavy volcanic eruptions... like the Krakatoa explosion!

It does totally break that model. We're led to believe an atmospheric event like that would shield the planet from solar radiation, thus cooling the planet. So does it act as a greenhouse effect, heating the planet instead?
It's also interesting to note the wild Co2 swings over time, unconnected to human activity. Though it does correlate with strong temperature gains...

Check this post: https://projectavalon.net/forum4/show...=1#post1235341 especially the addendum where the data studied show that the temperature increase precedes the CO2 increase by 600-800 years... so that, as I posted overthere, the sequence is as follows:
Volcanic/meteoritic/cosmic increase in dust concentration ---> increase in temperature ---> increase in atmospheric CO2

Re: Dust Particles Influence On The Weather AND Earth's Climate
Now, for the dust, temperature and solar activity entanglement, from: Carbon Dioxide and Air Temperature: Who Leads and Who Follows?: Even if CO2 has largely followed air temperature over the past 800,000 years, could it now become the leader in the 21st Century?
To address this question, Soon (2005) compared Arctic-wide surface air temperature anomalies with annual values of CO2 obtained from the climate modeling group at NASA GISS. The Arctic region is particularly important as climatologists widely agree that changes in air temperature are more pronounced in high latitudes due to the ice/snow-albedo feedback (i.e., melting ice and snow uncovers a darker underlying land surface that absorbs more solar radiation which increases the air temperature even more), the fact that cold air has very little moisture even when saturated (water vapor has a higher specific heat than dry air), and that it takes more energy to change the temperature of warm air by 1K than cold air (i.e., the derivative of the Stefan-Boltzmann radiation law).
The plot below from Soon (2005) shows the graph of yearly CO2 and Arctic-wide surface air temperature anomalies from 1875 to 2000. Changes in atmospheric CO2 fail to explain the warming between 1920 and 1960 and the percent of variance in air temperature explained by CO2 (i.e., the square of the correlation) is less than 20%. When smoothed by a decadal filter (to reduce the effects of short-term climate variability), the explained variance increases only to 22%.
By contrast, the graph of total solar irradiance (i.e., incoming solar energy) and Arctic-wide surface air temperature anomalies versus year (below) shows a much better correspondence with more than 40% of the variance in air temperature explained by total solar irradiance. But when the decadal filter is applied, the explained variance increases to nearly 80%.
While correlation certainly does not imply causality, it is very easy to argue on a physical basis that changes in solar irradiance should drive changes in atmospheric surface air temperature. Nevertheless, we can conclude that CO2 is not as good at predicting changes in Arctic-wide surface air temperature as is solar variability.
========================================================
So, the deciding factor for dust in polar regions is this one:

The Arctic region is particularly important as climatologists widely agree that changes in air temperature are more pronounced in high latitudes due to the ice/snow-albedo feedback (i.e., melting ice and snow uncovers a darker underlying land surface that absorbs more solar radiation which increases the air temperature even more)
Anyone having observed snow melting would have noticed its surface becoming "dirtier and dirtier" due to the dust, soot, particle residues left behind the melted snow as a concentrated top layer and facilitating a speedier melting of the snow it covers...
Since the recorded paleo-temperatures are coming from Greenland's and Antarctica's ice cores, the correlation between
dust ---> temperature increase is thoroughly logical and rational but not necessarily applicable to the more temperate to equatorial areas where "dust clouds" may generate "Years without Summers." :)
PS: I finally found what their "dust" is: they call it "Desert Dust" as a result of turbulent winds sweeping barren, cold desertic areas (Loess, in other words) which they correlate to glacial episodes as compared to "interglacial" where there is little of that dust with higher surface temperature.

Mysterious Substance and 'Devilry' Blamed for 3-Hour 'Solar Eclipse' in Russia
By Brandon Specktor, Senior Writer | July 23, 2018 04:30pm ET
For the Russian republic of Yakutia (also called Sakha) — a chunk of Siberia that's home to the coldest cities in the world — July is a welcome reprieve from the seven-month winter that rampages from October through April. It's a rare time of year when locals can step outside without the risk of their spectacles freezing to their faces, a time when the merciful sun can hang in the sky for more than 20 hours a day instead of less than 2.
Imagine the confusion and disappointment, then, when locals in at least two districts of Yakutia stepped outside Friday afternoon (July 20) and saw the sun completely blotted out for 3 hours. [Photos: 2017 Great American Solar Eclipse]
According to the regional news site Yakutia 24, the Eveno-Bytantaysky and Zhigansky districts of Yakutia inexplicably plunged into 3 hours of mysterious darkness between 11 a.m. and 2 p.m. local time on Friday. Photos provided by bewildered locals show little more than the black shadows of trees and buildings cast against a reddish haze of sky. Adding to the ominous atmosphere, the air seemed to be thick with a grimy haze of black dust.
"It was impossible to be in the street," witnesses of the bizarre event told the news site Sakha Daily. Other locals reported that it was suddenly pitch-black in their homes, that the mysterious smog turned barrels of water into barrels of mud and that nearby lakes emerged from the eclipse covered in a filthy, black layer of pollution.
… Happy summer!
So, what was behind this mysterious dirty eclipse? While one local blamed the incident on "devilry," there is a likelier culprit: the multiple forest fires burning around Yakutia and elsewhere in Siberia, The Siberian Times reported.
As NASA's Earth Observatory reminds us, it's wildfire season in Siberia, and hundreds of fires have already burned tens of thousands of acres of forest since May. While most of these fires are hundreds of miles away from the dust-eclipsed towns in question, smoke and aerosols released by some of these fires have been tracked halfway around the world. One cluster of fires sparked on July 3 produced a smoke plume so massive that it traveled more than 5,000 miles (8,000 kilometers) in the span of 11 days, passing across northeastern Russia, through Alaska and into central Canada before beginning to weaken.
Plumes this large can easily shade the land below and fill the air with polluting gases, NASA scientists wrote. However, as of today (July 23), no firm conclusions about the crud eclipse in Yakutia have been reached.

Massive sandstorm engulfs the city of Golmud, China
Tiffany Lo Daily Mail
Thu, 26 Jul 2018 14:19 UTC
A huge sandstorm yesterday swept across a city in northern China within minutes.
Apocalyptic video footage, taken by residents, shows how the cloud of thick dust more than 100 feet tall engulfed the city of Golmud in Qinghai Province.
The sandstorm was accompanied by gale-force winds of up to 20.7 metres per second, according to China Global Television Network.
Sandstorms, affected by a trail of cold air at ground level, have battered parts of China this week.
The film clips, released by China Central Television, show an apocalyptic sight of dust cloud rolling in over the city.
The dust cloud appeared over 50 metres high (164ft) and covered the city in a few minutes.
According to China Central Television, the storm brought down trees, caused damage and reduced visibility to under 600 metres (1,968ft) in the city and under 100 metres (328ft) in suburb area.
Golmud police issued warnings through loudspeakers and flashed emergency lights to remind road users to drive slowly.
Drivers were told to drive at a maximum speed of 25 miles per hour, stated the report.
The sandstorm comes just days after are heavy rainfall pummelled Golmud highlands and regions around Tuotuo River.
Golmud meteorological authority issued thunderstorm alerts today and suggested residents to stay indoors.
Local government has not received any reports of casualties.

Thanks Hervé. I really enjoyed the video and learned a lot.
It deals with:
- not only water, ice and vapor, but a fourth phase of water EZ, the necessary condition for the freezing of water.
- evaporation.
- condensation. What makes clouds?
- precipitation: - rain is pulled towards the earth, it doesn't fall. There is a pulling force that brings it to the earth.
- wind.
- and weather exotica, like hurricanes and tornadoes.
This presentation by Gerald Pollack offers a fresh overview of possible mechanisms of weather. It will propose answers to these questions and offer insights into possible mechanisms of common, as well as exotic, weather phenomena such as hurricanes and tornadoes.
Weather, after all, is a phenomenon centered on water — if EZ (fourth-phase) water exists, then it must play some role in those phenomena. The question we address is how, and Dr. Pollack postulates that charge plays a central role.
The central feature of all of this is 'charge'. Negative charge and positive charge.
We have to realize that it all depends on the electrical charge of the atmosphere and that the universe is really electrical !

Re: Dust Particles Influence On The Weather AND Earth's Climate
Mystery in the mesosphere: Noctilucent clouds TRIPLE compared to last August
Spaceweather.com
Thu, 16 Aug 2018 04:06 UTC
Anthony Watts Watts Up with That
Wed, 15 Aug 2018 19:50 UTC
Via NASA: extra water vapor in the mesosphere is creating more glowing nighttime clouds
This summer, something strange has been happening in the mesosphere. The mesosphere is a layer of the atmosphere so high that it almost touches space. In the rarefied air 83 km above Earth's surface, summertime wisps of water vapor wrap themselves around specks of meteor smoke. The resulting swarms of ice crystals form noctilucent clouds (NLCs), which can be seen glowing in the night sky at high latitudes.
And, no, that's not the strange thing.
Northern sky watchers have grown accustomed to seeing these clouds in recent years. They form in May, intensify in June, and ultimately fade in July and August. This year, however, something different happened. Instead of fading in late July, the clouds exploded with unusual luminosity. Kairo Kiitsak observed this outburst on July 26th from Simuna, Estonia:
"It was a mind-blowing display," says Kiitsak.
"The clouds were visible for much of the night, rippling brightly for at least 3 hours."
Other observers saw similar displays in July and then, in August, the clouds persisted. During the first half of August 2018, reports of NLCs to Spaceweather.com have tripled compared to the same period in 2017. The clouds refuse to go away.
Researchers at the University of Colorado may have figured out why."There has been an unexpected surge of water vapor in the mesosphere," says Lynn Harvey of Colorado's Laboratory for Atmospheric and Space Physics (LASP).
This plot, which Harvey prepared using data from NASA's satellite-based Microwave Limb Sounder (MLS) instrument, shows that the days of late July and August 2018 have been the wettest in the mesosphere for the past 11 years:
"July went out like a lion!" says Harvey.
In addition to being extra wet, the mesosphere has also been a bit colder than usual, according to MLS data. The combination of wet and cold has created favorable conditions for icy noctilucent clouds.
Harvey and her colleagues are still working to understand how the extra water got up there. One possibility involves planetary wave activity in the southern hemisphere which can, ironically, boost the upwelling of water vapor tens of thousands of miles away in the north. The phenomenon could also be linked to solar minimum, now underway. It is notable that the coldest and wettest years in the mesosphere prior to 2018 were 2008-2009-the previous minimum of the 11-year solar cycle.
SOTT Comment:
Late-season surge in Noctilucent Clouds produces stunning displays In 2017 a heat wave in the mesosphere melted those crystals, causing a brief "noctilucent blackout." Could something similar, but opposite, be happening now? Perhaps a cold spell in the mesosphere is extending the season.
In July an English astronomer reported photographing more noctilucent clouds in six weeks than in the last three years.
See also: Are noctilucent clouds increasing because of the cooling climate, and the rise of fireball and volcanic activity?
With the rise in rare and unexplained phenomena in our skies, clearly something is changing in our atmosphere:

Napoleon's defeat at Waterloo partly caused by massive volcano 'short circuiting' electrical current in atmosphere, study suggests
Samuel Osborne The Independent
Thu, 23 Aug 2018 07:00 UTC
Heavy rain across Europe played key role in French emperor's defeat at Battle of Waterloo
A gigantic volcanic eruption in Indonesia led to the wet and muddy conditions which contributed to Napoleon Bonaparte's defeat at the Battle of Waterloo, a study has suggested.
Two months before the battle changed the course of European history, Mount Tambora erupted on the Indonesian island of Sumbawa, killing 100,000 people and hurling huge plumes of ash up to 62 miles into the atmosphere.
The electrically-charged ash "short circuited" the ionosphere, the upper atmospheric layer responsible for cloud formation, researchers from Imperial College London said.
It led to a "pulse" of cloud formation which brought heavy rain across Europe and played a part in the French emperor's defeat.
Lead scientist Dr Matthew Genge said: "Previously, geologists thought that volcanic ash gets trapped in the lower atmosphere, because volcanic plumes rise buoyantly. My research, however, shows that ash can be shot into the upper atmosphere by electrical forces."
A series of experiments and computer simulations showed charged volcanic particles smaller than 0.2 millions of a metre in diameter could be propelled into the ionosphere during large eruptions.
There, they disturbed electrical currents in the ionosphere, leading to unusual levels of cloud formation and rain, according to the study published in the journal Geology.
Similar disturbance to the ionosphere was reported after the 1991 eruption of Mount Pinatubo in the Philippines.
Dr Genge added: "Victor Hugo in the novel Les Miserables said of the Battle of Waterloo: 'an unseasonably clouded sky sufficed to bring about the collapse of a world'.
Now we are a step closer to understanding Tambora's part in the battle from half a world away."

Funny you mention the Spanish Armada, I was thinking the same thing, and how Queen Elizabeth’s Conjurer, John Dee, was the astrologer/alchemist whom the queen relied on for making political moves on auspicious dates. What if Dee had an understanding of astronomy profound enough, that in the vein of Piers Corbyn (and his Weather Action methodology), could identify the most likely times major storms would be triggered by planetary movements. If you could entice your enemy to attack during those moments, would it not appear as sorcery as the enemies armada gets swept away by the raging waves.

Even Shakespeare, who knew Dee, based Prospero, the magician protagonist in The Tempest on John Dee, in this, the Bard’s final written work.
Dee is important for many reasons. One is that he found find a way to unite magic and science. As a good magician he inhabited a world between these two frontiers, and in the manner of the great Merlin, he was essential to the creation of the very archetype of the sorcerer, a figure who caught the attention of royalty like few others of his time. Perhaps John Dee’s mind was too advanced for that time. He might also be considered one of the first scientists, at a time when the line between science and metaphysics was only first being traced.
And if they had that technology in the late 1500’s, could the same technology be used to manoeuvre Napoleon to his armies demise several centuries later? The more I read about the Phoenicians, the more I believe they understood this deep understanding of astronomy and it’s relation to earth weather systems, as a way to plan safe sailing routes without encountering ferocious storms.

Very interesting, Jayke! Have often wondered about John Dee, myself! I'm beginning to think those who do understand the motions of the solar system are more clued in to what is happening. We have been dumbed down for so many centuries, it is ridiculous!! :facepalm:

The electrically-charged ash "short circuited" the ionosphere, the upper atmospheric layer responsible for cloud formation, researchers from
Imperial College London said.
It led to a "pulse" of cloud formation which brought heavy rain across Europe and played a part in the French emperor's defeat.
Lead scientist Dr Matthew Genge said:
"Previously, geologists thought that volcanic ash gets trapped in the lower atmosphere, because volcanic plumes rise buoyantly. My research, however, shows that ash can be shot into the upper atmosphere by electrical forces."
A series of experiments and computer simulations showed charged volcanic particles smaller than 0.2 millions of a metre in diameter could be propelled into the ionosphere during large eruptions.

Rethinking the mystery of stratospheric cooling

Watts Up With That

This paper claims that stratospheric cooling is the work of "greenhouse gases". Saying: "An extended satellite temperature record and the chemistry‐climate models show weaker global stratospheric cooling over 1998-2016 compared to 1979-1997."

SSU = Stratospheric Sounding Unit.
Of course, the authors, being biased towards the universal boogeyman of CO2, had only one thing on their minds. But a recent essay by Dr. Tony Phillips suggests the lower solar activity has cooled the thermosphere, which could in turn aid the cooling of the stratosphere:
From the plain language description of the publication: A previous analysis by Thompson et al. (2012, https://doi.org/10.1038/nature11579) showed substantial differences between satellite‐observed and model‐simulated stratospheric cooling trends since the late 1970s.
Here we compare recently revised and extended satellite temperature records with new simulations from 14 chemistry‐climate models. The results show much better agreement in the magnitude of stratospheric cooling over 1979-2005 between models and observations.
This cooling was predominantly driven by increasing greenhouse gases and declining stratospheric ozone levels. An extended satellite temperature record and the chemistry‐climate models show weaker global stratospheric cooling over 1998-2016 compared to 1979-1997. This is due to the reduction in ozone‐induced cooling from the slowdown of ozone trends and the onset of ozone recovery since the late 1990s.
There are larger differences in the latitudinal structure of past stratospheric temperature trends due to the effects of unforced atmospheric variability.
In summary, the results show much better consistency between simulated and satellite‐observed stratospheric temperature trends than was reported by Thompson et al. (2012, https://doi.org/10.1038/nature11579) for the previous versions of the satellite record and last generation of chemistry‐climate models. The improved agreement mainly comes from updates to the satellite records, while the range of simulated trends is comparable to the previous generation of models.

Abstract
Simulated stratospheric temperatures over the period 1979-2016 in models from the Chemistry‐Climate Model Initiative are compared with recently updated and extended satellite data sets. The multimodel mean global temperature trends over 1979-2005 are −0.88 ± 0.23, −0.70 ± 0.16, and −0.50 ± 0.12 K/decade for the Stratospheric Sounding Unit (SSU) channels 3 (~40-50 km), 2 (~35-45 km), and 1 (~25-35 km), respectively (with 95% confidence intervals). These are within the uncertainty bounds of the observed temperature trends from two reprocessed SSU data sets. In the lower stratosphere, the multimodel mean trend in global temperature for the Microwave Sounding Unit channel 4 (~13-22 km) is −0.25 ± 0.12 K/decade over 1979-2005, consistent with observed estimates from three versions of this satellite record. The models and an extended satellite data set comprised of SSU with the Advanced Microwave Sounding Unit‐A show weaker global stratospheric cooling over 1998-2016 compared to the period of intensive ozone depletion (1979-1997). This is due to the reduction in ozone‐induced cooling from the slowdown of ozone trends and the onset of ozone recovery since the late 1990s. In summary, the results show much better consistency between simulated and satellite‐observed stratospheric temperature trends than was reported by Thompson et al. (2012, https://doi.org/10.1038/nature11579) for the previous versions of the SSU record and chemistry‐climate models. The improved agreement mainly comes from updates to the satellite records; the range of stratospheric temperature trends over 1979-2005 simulated in Chemistry‐Climate Model Initiative models is comparable to the previous generation of chemistry‐climate models.

Temperatures have dropped to -91°C (-131,8°F) in the stratosphere!
===============================================
With a cooling of the stratosphere, dust particles wandering around in the upper atmosphere are more likely to form noctilucent clouds along with persistent contrails.
Also, a stronger temperature gradient between surface and stratosphere would account for more weather weirdness...

Hello yelik,
I moved this post of yours from the "EMFs - Electro Magnetic Fields - pollution: Their lethally detrimental effects and effective counteractive solutions." thread, where it was completely off topic, to this thread where the Weathertech ionization technology correlates with, and corroborates, Gerald Pollack's research.

Re: Dust Particles Influence On The Weather AND Earth's Climate
Earth just narrowly dodged bulk of Draconids meteor storm
Space Weather
Sun, 14 Oct 2018 15:33 UTC
On Oct. 8-9, Europeans outdoors around midnight were amazed when a flurry of faint meteors filled the sky. "It was a strong outburst of the annual Draconid meteor shower," reports Jure Atanackov, a member of the International Meteor Organization who witnessed the display from Slovenia. Between 22:00 UT (Oct. 8) and 01:00 UT (Oct. 9), dark-sky meteor rates exceeded 100 per hour. In eastern France, Tioga Gulon saw "1 to 2 meteors per minute," many of them shown here in an image stacked with frames from his video camera:
"It was a rare and impressive event," says Atanackov.
It could easily have been 10 times more impressive. In fact, Earth narrowly dodged a meteor storm.
The European outburst occurred as Earth skirted a filament of debris from Comet 21P/Giacobini-Zinner. If that filament had shifted in our direction by a mere 0.005 AU (~500,000 miles), Earth would have experienced a worldwide storm of 1000+ meteors per hour. These conclusions are based on a computer model of the comet's debris field from the University of Western Ontario's Meteor Physics Group.
Western Ontario postdoctoral researcher Auriane Egal created the model and predicted the outburst before it happened. Egal's model was in good agreement with a rival model from NASA, so confidence was high. Meteors seen over Europe came from the larger filament on the right.
According to the models, Earth's L1 and L2 Lagrange points were both forecast to have storm-level activity--especially L2 which would experience the Earth-equivalent of 4000+ meteors per hour. This prompted NASA to take a close look at the danger to spacecraft. "The US has four space weather spacecraft at L1: ACE, SOHO, Wind, and DSCOVR," says Bill Cooke of NASA's Meteoroid Environment Office.
"There is only one operational spacecraft at L2 - the European Space Agency's GAIA - which was where most of the Draconid activity was expected to take place. GAIA shut down science operations for a few hours around the projected storm peak and re-oriented to turn the hard side of the vehicle towards the incoming debris. All of the spacecraft came through the Draconids without incident, and this shower provided a good test of our ability to forecast meteor activity outside of Earth orbit."
Many readers have wondered if the outburst has anything to do with Comet 21P/Giacobini-Zinner's close approach to Earth last month."No," says Cooke.
"The models show the outburst experienced at Earth was mainly caused by material ejected from the comet from 1945 to the mid 1960's. The meteoroids were more than half a century old."
