Arctic Atmospheric Circulation, Freshwater and Sea Surface Height

NASA 2012: The transpolar drift (purple arrows) is a dominant circulation feature in the Arctic Ocean that carries freshwater runoff (red arrows) from rivers in Russia across the North Pole and south towards Greenland. Under changing atmospheric conditions, emergent circulation patterns (blue arrows) drive freshwater runoff east towards Canada, resulting in freshening of Arctic water…

Like Champagne opened, methane explosions resulted in Ocean craters

Like ‘champagne bottles being opened’: Scientists document an ancient Arctic methane explosion What could possibly go wrong, ignoring climate change, the warnings or clues from what science tells us, even if we were just creating a better world with clean energy, and millions of new jobs? One thing which could go very wrong, are based…

Methane in the East Siberian Arctic Shelf (2017)

The East Siberian Arctic Shelf has received more attention in recent years in regards to a potential contribution of the greenhouse gas methane, for the global methane budget, from several different sources. However, more studies are required to better constrain this potential accelerator of ongoing climate change.

Over 200 Arctic lakes seeping methane gas

Satellite images have revealed more than 200 strange, bright blue lakes in Russia’s Arctic regions that are leaking methane gas.

Arctic and Antarctic sea ice at lowest since satellites began to measure 1979

Sea Ice Extent Sinks to Record Lows at Both Poles Arctic sea ice appears to have reached on March 7 a record low wintertime maximum extent, according to scientists at NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. And on the opposite side of the planet, on March 3…

NASA: 2016 Arctic Sea Ice Minimum Ties Second Lowest on Record

Arctic sea ice appeared to have reached its annual lowest extent on Sept. 10, NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado at Boulder reported today. An analysis of satellite data showed that at 1.60 million square miles (4.14 million square kilometers), the 2016 Arctic sea ice…

Watch Bubbling Alaska Lakes Catch on Fire #Methane

Seeping methane is driving a global warming feedback loop. Some Arctic lakes are starting to look like witches’ cauldrons. The above video shows an increasingly common site in northern latitudes. As global warming heats these areas up, the frozen ground is melting. And when permafrost turns from solid ground to looser mud, it releases gases…

NASA/NSIDC: 2016 Arctic sea ice wintertime extent hits another record low

  2016 Arctic sea ice wintertime extent hits another record low By Maria-Jose Viñas, NASA’s Earth Science News Team Excerpt Arctic sea ice appears to have reached a record low wintertime maximum extent for the second year in a row, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.…

Ice sheets may be hiding vast reservoirs of methane

The study indicates that under the frigid weight of Barents Sea Ice sheet, which covered northern Eurasia some 22 000 years ago, significant amounts of methane may have been stored as hydrates in the ground. As the ice sheet retreated, the methane rich hydrates melted, releasing the climate gas into the ocean and atmosphere for…

AGU 2015: Jennifer Francis recent studies on Weather Blocking Patterns

Recent Changes in Blocking Characteristics Assessed Using Self-Organizing Maps Speaker: Jennifer Ann Francis Blocking anticyclones are known to be associated with persistent weather patterns that often lead to extreme weather events. An outstanding question, however, is whether the frequency and/or intensity of these dynamical features are changing in response to human-caused climate change, and in…

Arctic Sea Ice Reaches 2015 Minimum Extent

Arctic Sea Ice Summertime Minimum Is Fourth Lowest on Record According to a NASA analysis of satellite data, the 2015 Arctic sea ice minimum extent is the fourth lowest on record since observations from space began. The analysis by NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado…

Bill McGuire: Modelling suggests with ice cap melt, an increase in volcanic activity

ClimateState interviewed Bill McGuire, Emeritus Professor of Earth Sciences at the University College London, one of Britain’s leading volcanologists and contributing author to the 2011 IPCC report. He called for an early tsunami warning system (2004, The Guardian) and warned in his book The Waking Giant, of the Earth response (more earthquakes, tsunamis and landslides)…
