Video: Dr Lori Bruhwiler (NOAA), elaborates briefly on new methane estimates, with the focus on the Arctic (September 2016). Methane emissions from fossil fuel development around the world are up to 60 percent greater than estimated by previous studies, according to new research led by scientists from NOAA and CIRES. The study found that fossil…
October 4, 2016 by The Siberian Times: New expedition in Laptev Sea suggests increase in the rate of underwater permafrost degradation. http://siberiantimes.com/ecology/others/news/n0760-arctic-methane-gas-emission-significantly-increased-since-2014-major-new-research/
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/
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…
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…
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…
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…
Climate change is real, so why the controversy and debate? Learn to make sense of the science and to respond to climate change denial in Denial101x, a MOOC from UQx and edX. Denial101x isn’t just a climate MOOC; it’s a MOOC about how people think about climate change. Any research used to develop this content…
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.
