Atlantic currents have seen 'drastic' changes: study

[irishspirit]

GENEVA — Scientists have found evidence of a "drastic" shift since the 1970s in north Atlantic Ocean currents that usually influence weather in the northern hemisphere, Swiss researchers said on Tuesday.

The team of biochemists and oceanographers from Switzerland, Canada and the United States detected changes in deep sea Atlantic corals that indicated the declining influence of the cold northern Labrador Current.

They said in the US National Academy of Science journal PNAS that the change "since the early 1970s is largely unique in the context of the last approximately 1,800 years," and raised the prospect of a direct link with global warming.

The Labrador Current interacts with the warmer Gulfstream from the south.

They in turn have a complex interaction with a climate pattern, the North Atlantic Oscillation, which has a dominant impact on weather in Europe and North America.

Corals Provide Evidence of Changes to Oceanic Currents


Examination of deep sea corals reveals that there have been drastic changes to oceanic currents in the western North Atlantic since the 1970s. The influence of the cold water Labrador Current, which is in periodic interchange with the warm Gulf Stream, has been decreasing continually since the 1970s. Occurring at the same time as Global Warming this phenomenon is unique in the past 2000 years.

Me and my buddy were discussing the atlantic current over new years . Noth Pole is melting, south pole is growing , alaska glacier is expanding , Ring of fire is active, lots of changes happening all in the name of earths evolution, were just here for the ride.
