Climate Change, Arctic Security and Methane Risks

Over the past year, the climate risks of methane (CH4) released from natural sources have attracted increasing media attention in scientific and media forums as “the Arctic climate threat that nobody’s even talking about yet.” Read the news release http://www.thearcticinstitute.org/climate-change-arctic-security-methane-risks/

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…

Ice sheet deglaciation and methane emissions, with the scope on Greenland’s melt season

On June 9 2016, Nuuk, the capital of Greenland, reached the warmest temperature ever recorded for the month of June anywhere on the island, 24 degrees Celsius (75 degrees Fahrenheit). An article from NSDIC, published June 22 elaborated on the broader situation: Surface melting on Greenland’s Ice Sheet proceeded at a brisk pace, with three…

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…

Research links abrupt paleoclimatic change to possible methane hydrate destabilization

Using a core sample from the Santa Barbara Basin, UCSB researchers decipher the history of paleoclimate change with surprising results By Julie Cohen (UCSB): Global climate change isn’t new — the phenomenon has been around for millions of years. But now, a core from the ocean floor in the Santa Barbara Basin provides a remarkable…

The Discovery of Abiotic Methane – A New Methane Hydrate Source (News Roundup)

A reservoir of abiotic methane has been discovered in the Arctic Ocean. This means that there is more of the greenhouse gas trapped under the seabed than previously thought.
