    For reference:

    These are based on ice MAXIMUMS, generally around late march when the ice reaches the furthest... in June it should be shrinking rapidly towards its minimum (The above article doesn't do a good job of articulating that).



    Note the extensive north American ice penetration..... we are on a RAPID correction to "colder" it seems.

    Two tankers trapped in ice near Russian Arctic port in midsummer

    Atle Staalesen The Barents Observer
    Thu, 21 Jun 2018 12:36 UTC



    Shipping in the Gulf of Ob is paralysed and the situation complicated, icebreaker company Rosatomflot says.


    It is late June, but the winter has not abandoned the Gulf of Ob. The shallow bay, which houses two of Russia's biggest Arctic out-shipment terminals for oil and gas, remains packed with fast ice.

    It has created a complicated situation, Rosatomflot says. The state company which manages the Russian nuclear-powered icebreakers, confirms that independent shipping in the area is paralysed and that LNG carriers and tankers are stuck.

    The shipping companies had expected the Gulf of Ob to be free of ice in the course of June and that icebreaker assistance would not be necessary. They were wrong.

    According to Rosatomflot, there appears to be a need for icebreaker services in the area at least until after the first week of July. There are currently two nuclear-powered icebreakers in the Gulf of Ob, the Taymyr and the Vaygach. In addition, there are several smaller tugs and icebreakers working in the waters around the Sabetta port.

    The Yamal LNG plant is fully dependent on smooth shipping to and from the port of Sabetta. A fleet of 15 powerful top ice-class carriers are being built for the project. The ships are capable of independently breaking through more than two meter thick ice. Commercial shipments from Sabetta started in early December 2017.

    Greenland Ice Sheet far above the mean

    July 5, 2018 by Robert

    5 July 2018 – This chart from the Danish Meteorological Institute (DMI) speaks for itself.

    The blue line shows Greenland ice-mass balance as of today. It is far, far greater than the mean curve – the average, if you will – from 1981 to 2010 (dark grey line).

    I doubt that you’ll see this reported by the mainstream media.


    Blue line: Accumulated surface mass balance from September 1st to now.
    Red line: Shows the 2011-12 season, which had very high summer melt in Greenland.
    Dark grey line: The mean curve from the period 1981-2010.
    Light grey band: Measurements were taken on the same calendar day from 1981-2010. Those differences are illustrated by the light grey band.

    Can this be trusted? I really don't know anymore!

    A Sluggish June

    Arctic sea ice extent declined at a slightly slower-than average pace in June. Despite the slow loss, warm conditions and winds from the south developed a large area of open water in the Laptev Sea.

    Arctic sea ice extent for June 2018 averaged 10.7 million square kilometers (4.1 million square miles). This was 1.05 million square kilometers (405,000 square miles) below the 1981 to 2010 average [my emphasis] and 360,000 square kilometers (139,000 square miles) above the record low June extent set in 2016. This was the fourth lowest June average extent in the satellite record.



    Extent at the end of June remained below average in the Chukchi Sea, but because of slow retreat through June in the region, extent in the Chukchi is now closer to average than was the case at the end of May. The Barents Sea and East Siberian Sea also have extents well below average at the end of June. Most of the ice in the Sea of Okhotsk has melted. Ice has been retreating in the west side of Hudson Bay where extent is below average. However, this is countered by above average extent in the eastern side of the bay. Notably, a large area of open water has developed in the Laptev Sea, leading to record low extents in that region during the first half of June.

    --------------------------

    Climate change is such a minefield. It's hard to nail down exactly who and what is telling the truth. I've had some heated discussions lately with a friend, both of us armed with conflicting data sets.

    I'm told that global-warming is very real, and all denials are [I quote] "a right-wing conspiracy theory". I do my best to argue otherwise, citing carbon tariffs as a viable motive for pushing the global warming narrative, while presenting many articles, graphs, charts, to suggest global cooling is in fact the trend -- but to no effect.

    Hervé, or anyone, I'd greatly appreciate a helping hand. Not because I'm trying to win a debate, I'm just trying to get a handle on the truth of climate change. I've followed this thread and lots of others, but it's still hard to figure who/what is the truth.
    • what is truly happening to the climate and why?
    • how do fossil fuels/carbon dioxide really affect climate?
    • why do some scientists/think tanks present conflicting theories?
    • if the climate is actually cooling, why do scientists/governments/lobbyists/media say [and very loudly] the exact opposite - that it's warming?

    Warm world? Look at the cold all over the map

    by Robert July 9, 2018

    If you were to believe the mainstream media, you’d think our world is burning up. But that is not true.

    Yes, there were places on our planet where it was warmer than normal today. But many parts of the world displayed normal or even colder than normal temperatures.

    Look at all of the white and blue on this map.


    • Large portions of the Atlantic Ocean were normal or colder than normal.
    • It was colder than normal across a lot of Africa.
    • It was colder than normal across almost all of the Arctic and the Arctic Ocean.
    • It was colder than normal across almost all of Greenland.
    • It was colder than normal across almost all of India.
    • It was colder than normal across almost all of Mexico.
    • It was colder than normal across central Europe.
    • It was colder than normal across most of Brazil.
    • It was colder than normal across Indonesia and the Philippines.
    • It was colder than normal across all of Antarctica (and remember, Antarctica is twice as big as the contiguous United States).
    • It was colder than normal across almost all of the Southern Ocean.
    Please, please remember that the media is not giving you the full story.

    I'd also welcome Hervé's reply. But here's my own take. We're starting to experience a repeat of this, which although it was called the 'Little Ice Age', also featured periods of wild climate fluctuation, including some very warm years.

    It's a very interesting documentary, well worth watching. All this may be what's in store now for Planet Earth for a little while.

    Watching Weather Waves, but Missing Climate Tides

    by Robert July 13, 2018
    “Earth’s natural thermometers are now flashing an amber warning. The long-term trends point to growing glaciers and falling sea level.”
    – Viv Forbes
    __________________


    Watching Weather Waves, but Missing Climate Tides

    By Viv Forbes, 11 July 2018

    The climate alarm media, the bureaucracy and the Green Energy industry follow an agenda which is served by inflating any short-term weather event into a climate calamity. They should take a long-term view.

    Earth’s climate is never still – it is always changing, with long-term trends, medium-term reversals and minor oscillations. Humanity is best served by those who use good science to study geology, astronomy and climate history searching for clues to climate drivers and the underlying natural cycles and trends hidden in short-term weather fluctuations.

    For the last 10,000 years Earth has basked in the Holocene Interglacial which is the latest of many warm cycles within the Pleistocene Ice Age. There are small warm and cool cycles within the Holocene. Today we enjoy the Modern Warm Cycle (which started about calendar 1900) following the Little Ice Age which bottomed in about 1750.

    What does the future hold? The past gives clues to the future.

    In every warm era, glaciers retreat, ice sheets melt and sea levels rise. Coastal land, ports and settlements are lost under the rising seas but tundra, grasslands and forests expand. Some corals manage to grow as fast as the seas rise, but others are drowned in deep water. The warmth drives more carbon dioxide from the seas, plants thrive, deserts shrink and humans are well fed.

    Then solar intensity wanes, solar orbits change, less solar energy is received by the big northern lands, and the warm Earth radiates more heat to space. It starts cooling.

    As Earth enters a cold era, not all of the winter snow melts over summer. The extra snow reflects more solar radiation, leading to even colder winters. The snow-line and the tree-line fluctuate lower, mountain passes are closed, and advancing glaciers threaten mountain villages. Sea ice expands, ice sheets grow, lakes and rivers are frozen, sea levels drop and coral reefs are stranded above the water line. The cooling seas absorb life-giving carbon dioxide from the atmosphere and crops fail; deserts expand, humans suffer poverty and famine, settlements are abandoned, empires fall and some species disappear.

    This has happened many times before and will probably happen again.

    But there are clues to the next big phase for Earth’s climate.

    Earth has two natural global thermometers which can reveal short and long term trends – the advance and retreat of glaciers, and the rise and fall of sea level.

    If glaciers are growing and ice sheets are advancing and getting thicker, it indicates that average global temperature is falling.

    No glacial ice older than 4,000 years
    Glaciologists have drilled and analysed many of today’s glaciers. They have been surprised to discover that, outside of Antarctica and Greenland, no glacial ice older than 4,000 years has been found. For example, the Fremont Glacier in Wyoming half-way towards the Equator is only a few hundred years old.

    Naturally some of these new glaciers can show melting and retreat during long spells of warm weather, but the mere existence of glaciers today where none existed at the peak of the Holocene warming over 3,000 years ago confirms what other studies show – Earth is gradually cooling towards the next Glacial Cycle.


    Greenland Ice Core Project (GRIP) –Temperature Reconstruction – “Falling for 3000 Years”
    From “The Inconvenient Skeptic” p 115 by John Kehr 2011, http://theinconvenientskeptic.com/

    The second natural thermometer is the changing sea level caused by fluctuations in the volume of ice and snow trapped on land, and by the expansion or contraction in the volume of sea water as it warms or cools.

    Coastal and near-shore locations show much evidence of past and recent sea level changes. In warm eras, glaciers and ice sheets melt, sea water expands, sea levels rise and offshore coral reefs become submerged and drown. Then as peak warming is passed, ice starts to accumulate on land, cooling sea water contracts and sea levels fall.

    Even a moderate cooling event such as the Little Ice Age was sufficient to cause lowering of sea level and stranding of port cities and beaches.

    Earth’s natural thermometers are now flashing an amber warning.

    The long-term trends point to growing glaciers and falling sea level. These warn us that the warm moist bountiful Holocene Era is past its peak. The next chapter in Earth’s History will be a long, hungry, ice-bound era. Only humans who are good at hunting and gathering or have easy access to nuclear power or carbon energy will survive.


    Temperature Reconstructions using deep sea sediment cores. (Raymo, 2005)
    From “The Inconvenient Skeptic” 2011 p42, by John Kehr http://theinconvenientskeptic.com/

    People who try to create a “Climate Crisis” out of extreme weather events or short-term climate fluctuations (such as today’s Modern Warm Cycle) are like Lord Nelson – their telescope is applied to the blind eye. They point to the choppy waves from summer storms behind the ship, but fail to see the blizzard approaching on the horizon ahead.

    Al Gore was right in one thing – warm cycles coincide with high levels of carbon dioxide in the atmosphere. The warmth drove CO2 into the atmosphere, and then the cooling oceans removed it again. Carbon dioxide variations are the result, not the cause, of climate changes.

    But never once, over eleven warm cycles covering the last million years, have those high levels of atmospheric carbon dioxide prevented the next glacial cycle.

    “Carbon Dioxide
    Causes Global Warming
    Like Wet Roads
    Cause Rain.”


    Trying to remove or limit atmospheric carbon dioxide is a futile and costly gesture. Even if it were to succeed, by removing plant food from the atmosphere, it would increase the misery of the approaching cold, hungry era.

    We may still have warm decades or even centuries ahead. But even when there is a heatwave in autumn, the winter still comes.

    Many thanks both, truly.

    But I'm still at a loss, as I still see conflicting data.

    This table for example plots Arctic sea ice for the month of June, from 1979 to present. If it can be trusted, it clearly depicts a decline.



    From: http://nsidc.org/arcticseaicenews/20...sluggish-june/

    The honest question remains, what do I trust?

    Because there is data coming from both angles, cooling and warming. Is one side cooking the numbers? If so, which side, and for what reason? How does one (without a degree in climatology or meteorology) learn to discern?

    Many thanks.

    ___________________________________

    Addendum:
    But now compare this graph closely with that presented by David and Gordon (2007). Although David and Gordon have drawn only the last 650,000 years (from Jouzel et al. 2007), their curve labeled as “climate temperature” matches the Lüthi et al. (2008) curve for carbon dioxide! And, not surprisingly, their curve labeled “CO2 Concentration in the Atmosphere” matches with the Lüthi et al. (2008) curve for air temperature anomaly! Clearly, in their haste to make a convincing argument that air temperature follows changes in CO2, David and Gordon (2007) have reversed the two curves. Thus, we can correct the David and Gordon graph on their page 18 to read:


    Now, it is clear from both curves and the science that backs them, that air temperature is the leading variable and that CO2 follows air temperature by about 600 to 800 years.

    In other words these are clear cases of fitting the data to the theory...

    As far as "climate" goes, this (posted (here)) appears to be a complete, total, radical game changer:

    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!


    Accordingly, the sequence is as follows:


    Volcanic/meteoritc/cosmic increase in dust concentration ---> increase in temperature ---> increase in atmospheric CO2

    The rationale being that oceanic warming releases CO2 in the atmosphere some centuries following the peak atmospheric temperatures in some kind of deferred domino effect.

    I spent the first 20 minutes of studying this graph not realizing that the time scale is backwards ... time increasing right to left .

    Well, backwards from the perspective of my math-physics habits. Perhaps it is I who thinks backwards, and geologists who have the arrow of time properly shown.

    Apparently the data for this chart comes from, or shares some of its origins with, this 1999 Nature article: Climate and atmospheric history of the past 420,000 years from the Vostok Ice Core.

    Temperatures are not directly measured from ice core samples using a thermometer ... that would be silly. Rather they are inferred by measuring the deuterium content of the ice, which is apparently a proxy for temperatures at the time the ice was formed. A proxy for which temps I wonder: local in the cloud where the rain formed that became the ocean water that became the ice, global or polar atmospheric, global or polar oceanic, Saturnian, ... ? Aha - the paper discusses this question in more detail in its "Temperature" section, but I'm too much of a geo-dunce to competently evaluate these details further.

    The time scale is also a matter of some, albeit apparently modest, technical difficulty, unlike say tree rings, which can easily be counted and correlated with the annual seasonal changes. See the "Vostok glaciological timescale" box of the paper for that discussion.

    Hervé - if you consider the above article to be worthy of further study, I'd be interested to read your analysis of it.

    @ Paul, like you, I gave up trying to follow their isotope ratios for tempreature determination. All I understood is that the gaseous inclusions are surface air bubbles trapped at the transition compacted snow ---> ice.

    As for the direction of the time scale, in general, geologists/geophysicists wouldn't do that but represent negative/past values to the left of the "0" (zero) and the positive/future ones to the right, as abscissas. So, my guess is that, that confusing notation, is from climatologists

    Betting on a catastrophically cooling world

    by Robert July 30, 2018

    The recent warming since the end of the Little Ice Age has been wholly beneficial when compared to the devastating impacts arising from the relatively minor cooling of the Little Ice Age.

    Betting on a catastrophically cooling world

    By Ed Hoskins
    According to ice core records, the last millennium 1000AD – 2000AD has been the coldest millennium of our current Holocene interglacial. This point is more fully illustrated with ice core records on a millennial basis back to the Eemian period here:


    Our current, warm, congenial Holocene interglacial, although cooler than the Eemian interglacial 120,000 years ago, has been the enabler of mankind’s civilisation for the last 10,000 years, spanning from mankind’s earliest farming to the most recent technologies.

    Viewing the current Holocene interglacial on a millennial basis is rational. But sadly it seems that, driven by the need to continually support the Catastrophic Anthropogenic Global Warming hypothesis / religion Climate alarmists irrationally examine the temperature record at too fine a scale, weather event by weather event, month by month, or year by year.

    From the broader perspective, each of the notable high points in the current 11,000 year Holocene temperature record, (Holocene Climate Optimum – Minoan – Roman – Medieval – Modern), have been progressively colder than the previous high point.

    The ice core records from Greenland for its first 7-8000 years, the early Holocene, shows, virtually flat temperatures, an average drop of only ~0.007 °C per millennium, including its early high point known as the “climate optimum”. But the more recent Holocene, since a “tipping point” at around 1000BC, 3000 years ago, has seen temperature fall at about 20 times that earlier rate at about 0.14 °C per millennium.

    The Holocene interglacial is already 10 – 11,000 years old and just judging from the length of previous interglacial periods, the Holocene epoch should be drawing to its close: in this century, the next century or this millennium.

    Nonetheless, the slight and truly beneficial warming at the end of the 20th century to a Modern high point has been transmuted by Climate alarmists into the “Great Man-made Global Warming Alarm”.

    The recent warming since the end of the Little Ice Age has been wholly beneficial when compared to the devastating impacts arising from the relatively minor cooling of the Little Ice Age, which include:
    • decolonisation of Greenland
    • Black death
    • French revolution promoted by crop failures and famine
    • the failures of the Inca and Angkor Wat civilisations
    • etc., etc.
    As global temperatures, after a short spurt at the end of the last century, have already been showing stagnation or cooling over the last nineteen years or more, the world should now fear the real and detrimental effects of cooling, rather than being hysterical about limited, beneficial or probably now non-existent further warming.

    Warmer times are times of success and prosperity for man-kind and for the biosphere. For example during the Roman warm period the climate was warmer and wetter so that the Northern Sahara was the breadbasket of the Roman empire.

    But the coming end of the present Holocene interglacial will eventually again result in a mile high ice sheet over much of the Northern hemisphere. As the Holocene epoch is already about 11,000 years old, the reversion to a true ice age is becoming overdue.

    That reversion to Ice Age conditions will be the real climate catastrophe.

    With the present reducing Solar activity, significantly reduced temperatures, at least to the level of another Little Ice Age are predicted quite soon this century.

    Whether the present impending cooling will really lead on to a new glacial ice age or not is still in question.

    As an interested layman, I would say that the betting is more heavily weighted towards a catastrophically cooling world rather than one that will be overheating because of the comparatively minor CO2 emissions from mankind.

    The glaciation and deglaciation of North America – Video

    Note that most of Alaska was NOT covered by ice.

    This video makes it abundantly clear that melting glaciers are nothing new.

    Laurentide Ice Sheet evolution. This animation integrates the state of the art knowledge about the retreat of the Laurentide Ice Sheet since the Last Glacial Maximum.

    Now I understand why all north american continental maps designed in the US stop at the border north, as if Canada did not exist. A blank instead of Canada. And why a vast quantity of Americans (in fact US citizens since The term American should include Canadians living in the continent) do not know there is anything north

    They mistakingly use the last glaciation map.

    Sorry, I could truly not resist a bit of sarcasm.
