The methane detectives: On the trail of a global warming mystery – “The bottom line is that methane is going up and doesn’t look like it will stop anytime soon”

By Jonathan Mingle 13 May 2019 (Undark) – Every week, dozens of metal flasks arrive at NOAA’s Earth System Research Laboratory in Boulder, Colorado, each one loaded with air from a distant corner of the world. Research chemist Ed Dlugokencky and his colleagues in the Global Monitoring Division catalog the canisters, and then use a series of […]

Rapid permafrost thaw unrecognized threat to landscape, global warming researcher warns – “We are watching this sleeping giant wake up right in front of our eyes”

Rapid permafrost thaw unrecognized threat to landscape, global warming researcher warns – “We are watching this sleeping giant wake up right in front of our eyes”

30 April 2019 (University of Guelph) – A “sleeping giant” hidden in permafrost soils in Canada and other northern regions worldwide will have important consequences for global warming, says a new report led by University of Guelph scientist Merritt Turetsky. Scientists have long studied how gradual permafrost thaw occurring over decades in centimetres of surface […]

Yukon warmest it has been in 13,600 years – “This region has been warming at an exceptional rate”

By Blake Eligh 9 April 2019 (University of Toronto) – A new University of Toronto study confirms that recent climate warming in the central Yukon region has surpassed the warmest temperatures experienced in the previous 13,600 years, a finding that could have important implications in the context of current global warming trends. In a study […]

Canada warming at twice the global rate, government report finds – “Northern Canada has warmed and will continue to warm at more than double the global rate”

1 April 2019 (CBC News) – Canada is, on average, experiencing warming at twice the rate of the rest of the world, with Northern Canada heating up at almost three times the global average, according to a new government report. The study — Canada’s Changing Climate Report (CCCR) — was commissioned by Environment and Climate […]

“Doomsday vault” town warming faster than any other on Earth – “The brutality of nature used to bring joy, but now it scares people”

By Sarah Lazarus 27 March 2019 (CNN) – In 2014, Mark Sabbatini noticed cracks in his apartment walls. Then a mysterious bulge appeared in his bedroom and the apartment block’s communal staircase became crooked. “Doors and windows weren’t shutting properly,” he says. Sabbatini, the editor of a local newspaper, was living in Longyearbyen, the world’s […]

3-5°C temperature rise is now “locked-in” for the Arctic

Nairobi, 13 March 2019 (UN News) – Even if the world were to cut emissions in line with the Paris Agreement, winter temperatures in the Arctic would rise 3-5°C by 2050 and 5-9°C by 2080, devastating the region and unleashing sea level rises worldwide, finds a new report by UN Environment. Meanwhile, rapidly thawing permafrost […]

Early spring rain boosts methane from thawing permafrost by 30 percent – “Permafrost regions are sensitive to the thermal effects of rain”

By Sarah McQuate4 February 2019 (UW News) – Arctic permafrost is thawing as the Earth warms due to climate change. In some cases, scientists predict that this thawing soil will release increasing amounts of methane, a potent greenhouse gas, that is known to trap more heat in our planet’s atmosphere. Now a University of Washington-led […]

Lawmakers tell Pentagon: Revise and resubmit your climate-change report

By Paulina Glass 5 February 2019 (Defense One) – The Pentagon’s latest climate-change report was so bad that it didn’t even meet legal requirements, say House lawmakers who on Wednesday ordered the military to redo the document by 1 April 2019.The report “lacks key deliverables,” according to the 25 January 2019 letter from House Armed […]

New global study reveals rising soil temperatures in permafrost regions around the world – “The permafrost isn’t simply warming on a local and regional scale, but worldwide and at virtually the same pace as climate warming”

16 January 2019 (AWI) – Global warming is leaving more and more apparent scars in the world’s permafrost regions. As the new global comparative study conducted by the international permafrost network GTN-P shows, in all regions with permafrost soils the temperature of the frozen ground at a depth of more than 10 metres rose by […]

Across the Arctic, lakes are leaking dangerous greenhouse gases – “These lakes speed up permafrost thaw. It’s an acceleration.”

By Chris Mooney 25 September 2018 (The Washington Post) – “The lake, about 20 football fields in size, looked as if it was boiling. Its waters hissed, bubbled and popped as a powerful greenhouse gas escaped from the lake bed. Some bubbles grew as big as grapefruits, visibly lifting the water’s surface several inches and […]
