Global warming, Arctic ice loss, and armchair scientists

Guardian: As humans put more and more heat-trapping gases into the atmosphere, the Earth's climate changes; we all know that. Some of the trickier questions are, how fast is it changing, what can we expect in the future, what are the costs of slowing emissions (compared to the costs of doing nothing), and what changes are we already observing that give us such confidence in our predictions? Perhaps the poster child of climate change is in the Arctic, where sea ice has been declining at an astonishing rate....
Norwegian government study raises investment risk fears over Arctic drilling

BusinessGreen: The development of oil and gas fields in the Arctic is unlikely to prove compatible with global efforts to tackle climate change, according to the latest major report to raise concerns over the formation of a 'carbon bubble'. The study, commissioned by the Norwegian Ministry of the Environment and undertaken by consultancy Rystad Energy, assessed the risk of the country's oil and gas industry being left with stranded assets as governments attempt to meet the global goal of restricting average...

How Much Should You Worry About an Arctic Methane Bomb?

Climate Desk: It was a stunning figure: $60 trillion. Such could be the cost, according to a recent commentary in the journal Nature, of the release of methane from thawing permafrost beneath the East Siberian Sea, off northern Russiaa figure comparable to the size of the world economy in 2012. More specifically, the paper described a scenario in which rapid Arctic warming and sea ice retreat lead to a pulse of undersea methane being released into the atmosphere. How much methane? The paper modeled a release...

Arctic ice grows darker and less reflective
2013-08-07 19:59:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: SUMMER was once an important time for reflection in the Arctic. Perhaps not for much longer: the Arctic Ocean now reflects 15 per cent less sunlight than it did 30 years ago. Aku Riihelä of the Finnish Meteorological Institute and his colleagues looked at satellite measurements of reflectivity, or albedo, between 1982 and 2009 (Nature Climate Change, doi.org/nct). He says the darkening is partly due to thinning ice and the formation of fissures, and partly because in the warmer air, ponds of liquid...

Climate change in 2012: record sea-level rise, Arctic melting, warmed oceans, report says
2013-08-06 23:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: A new massive U.S. study says the world in 2012 sweltered with continued signs of climate change. Rising sea levels, snow melt, heat buildup in the oceans, and melting Arctic sea ice and Greenland ice sheets, all broke or nearly broke records, but temperatures only sneaked into the top 10. The National Oceanic and Atmospheric Administration on Tuesday issued a peer-reviewed 260-page report, which agency chief Kathryn Sullivan calls its annual "checking on the pulse of the planet." The report,...
