Arctic Methane Venting

Methane venting in the Arctic appears to have dramatically increased between February 2013 and February 2014.  This appears to have been created by rising sea water temperatures that have changed the behavior of the Gulf Stream and Jet Stream.  There is a concern that these phenomena will create rapid irreversible changes in the atmosphere and biosphere.  If the current trend continues, the human condition globally may be dramatically changed to negative in a matter of years to decades.

Danger of Methane Explosions on Yamal Peninsula, Scientists Warn

      

Scientists from the respected Trofimuk Institute of Petroleum Geology and Geophysics insist the process by which a series of craters formed was caused by the melting of gas hydrates and the emission of methane. Picture: Vladimir Olenchenko/Trofimuk Institute of Petroleum Geology and Geophysics

More craters expected to form due to such eruptions as permafrost melts - and they ARE caused by global warming releasing methane gas.

siberiantimes.com - by Anna Liesowska - September 22, 2015

A new expedition to one of the mysterious Siberian giant holes found in recent years has concluded that it is a warning sign of a deadly threat to northern regions as the climate warms. . . .

. . . A pingo believed to be poised to explode 'at any moment' is now being constantly monitored by a Russian space satellite in an attempt to catch the moment when the eruption occurs. . . .

. . . The scientists also warn of a dire threat to both towns and cities in the extreme north, and natural gas exploration facilities and associated pipelines.

Arctic Seafloor Methane Releases Double Previous Estimates

The seafloor off the coast of Northern Siberia is releasing more than twice the amount of methane as previously estimated, according to new research results published in the Nov. 24 edition of the journal Nature Geoscience.

The East Siberian Arctic Shelf is venting at least 17 teragrams of the methane into the atmosphere each year. . .

High Methane Levels Over the Arctic Ocean

                                             (CLICK ON POSTER IMAGE BELOW TO ENLARGE)

arctic-news.blogspot.com - February 19, 2014

High methane concentrations have persistently shown up over the Arctic Ocean since October 1, 2013.

The danger is that methane will further warm up the air over the Arctic, causing further weakening of the Jet Stream and further extreme weather events, particularly extreme warming of water all the way along the path of the Gulf Stream from the Atlantic Ocean into the Arctic Ocean, in turn triggering further releases from hydrates at the seafloor of the Arctic Ocean and escalating into runaway global warming.

Arctic Methane Time Bomb Could Have Huge Economic Costs

      

Increasing temperatures in the Arctic region are reducing sea ice cover and increasing the possibility of methane leaching from the sea bed

bbc.co.uk - by Matt McGrath - July 24, 2013

Scientists say that the release of large amounts of methane from thawing permafrost in the Arctic could have huge economic impacts for the world.

The researchers estimate that the climate effects of the release of this gas could cost $60 trillion (£39 trillion), roughly the size of the global economy in 2012.

The impacts are most likely to be felt in developing countries they say.

The research has been published in the journal Nature.

NOAA Report - State of the Climate in 2011

noaa.gov - July 10, 2012

Back-to-back La Niñas cooled globe and influenced extreme weather in 2011

New NOAA-led report examines climate conditions experienced around the world

Worldwide, 2011 was the coolest year on record since 2008, yet temperatures remained above the 30 year average, according to the 2011 State of the Climate report released online today by NOAA. The peer-reviewed report, issued in coordination with the American Meteorological Society (AMS), was compiled by 378 scientists from 48 countries around the world. It provides a detailed update on global climate indicators, notable weather events and other data collected by environmental monitoring stations and instruments on land, sea, ice and sky.

Arctic Melt Releasing Ancient Methane

Many of the sites were bubbling methane that has been stored for millennia

BBC News - by Richard Black - May 20, 2012

Scientists have identified thousands of sites in the Arctic where methane that has been stored for many millennia is bubbling into the atmosphere.

The methane has been trapped by ice, but is able to escape as the ice melts.

Writing in the journal Nature Geoscience, the researchers say this ancient gas could have a significant impact on climate change.

Methane is the second most important greenhouse gas after CO2 and levels are rising after a few years of stability.
