FIFTY? Fifty self-reinforcing feedback mechanisms are now active? University of Arizona professor emeritus, natural resources, ecology and evolutionary biology, Guy McPherson no longer pursues pure science, environmental research. He can’t. He’s too busy digesting the mountains of research pouring in from other scientists and connecting the dots.
There’s really no nice way to put this. McPherson has now logged 50 self-reinforcing feedback mechanisms underway. That’s another way of saying “runaway global warming.” At the time of the interview below, back in March, he’d only identified 39. Apparently eleven more have turned up since then.
In Dr. McPherson’s assessment, we’re (Read more…)

My documentary on the impacts of climate change in the Greenlandic village of Uummannaq aired in December on the Deutsche Welle international radio program Living Planet. I recorded and produced this report while working as the on-board journalist during the 2013 Students on Ice Arctic Expedition.
Located on a small island off the Greenland coast, 600 km (372 miles) north of the Arctic Circle, Uummannaq is one of many Inuit communities in the North that are already experiencing the impacts of climate change. Not only (Read more…)

Reading this press release about a new paper in Palaeogeography, Palaeoclimatology, Palaeoecology spoiled my day. It might not be obvious to a casual reader just glancing through the morning news — but a couple of paragraphs leapt out at me:
Atmospheric carbon dioxide concentrations recently reached 400 parts per million for the first time since the Pliocene Epoch, three million years ago. During this era, Arctic surface temperatures were 15-20 degrees Celsius warmer than today’s surface temperatures.
Ballantyne’s findings suggest that much of the surface warming likely was due to ice-free conditions in the (Read more…)
* There have been five arrests this week of people protesting the presence of SWN Resources Canada on traditional Mi’kmaq territory in New Brunswick. The protests are being led by First Nations leaders, and are a result of the fears that SWN’s seismic testing will result in hydraulic fracturing, or fracking, on the land. Read more […]
The domestic and international security implications of an ice free Arctic ocean will be briefed at the White House this week.
The meeting is bringing together Nasa’s acting chief scientist, Gale Allen, the director of the US National Science Foundation, Cora Marett, as well as representatives from the US Department of Homeland Security and the Pentagon. Senior scientists advising the US government at the meeting include 10 Arctic specialists, including marine scientist Prof Carlos Duarte, director of the Oceans Institute at the University of Western Australia.
In early April, Duarte warned that the Arctic summer sea ice was melting (Read more…)
Holy sh*t – if this video doesn’t alarm the heck out of you, you don’t have a pulse! New findings on the state of the Arctic sea ice, resulting from a collaboration between many international agencies, confirm new data collected from the European Space Agency’s CryoSat-2 satellite spanning 2010 to 2012, and data from NASA’s [...]
* As Joe Romm at ThinkProgress points out, this should be the story of the week/year/decade: Now the Natural Environment Research Council (NERC), the UK’s primary agency for funding and managing environmental sciences research, has made it official. In a Wednesday press release, they report: Arctic sea ice volume has declined by 36 per cent in [...]
