“We’re in the final few months of what’s shaping up to be the hottest year on record. In September, Arctic sea ice melted to its smallest extent in satellite records, while the Midwest was rocked by a once-in-a-generation level drought. Global carbon dioxide emissions hit a record high in 2011 of 34.83 billion tons, and they will almost certainly be higher this year….Given all that, it might seem reasonable to think that climate change —and how the U.S. should respond to it — would be among the top issues of the 2012 presidential election.” Instead, climate change has gone largely unmentioned.

Washington Post (August 27)
“The extent of Arctic sea ice has reached a record low, a historic retreat that scientists said is a stark signal of how climate change is transforming the global landscape.” Typically the summer low comes in mid-September so the ice cover may continue to shrink beyond its current size of 1.58 million square miles. This year, “the ice melted at an unprecedented 38,600 square miles per day during the first part of August.”

Glaciers are retreating and permafrost is thawing in the Arctic, where June snow cover is just 80% of what it was in the 1960s. As the habitat changes, some species will win and others will lose. “Perhaps not since the 19th-century clearance of America’s forests has the world seen such a spectacular environmental change. It is a stunning illustration of global warming, the cause of the melt. It also contains grave warnings of its dangers. The world would be mad to ignore them.”Glaciers are retreating and permafrost is thawing in the Arctic, where June snow cover is just 80% of what it was in the 1960s.

The Economist (September 24)
Arctic ice is disappearing faster than previously thought. The ice is now estimated to be just half as thick as it was 1979 “and there is probably less ice floating on the Arctic Ocean now than at any time since a particularly warm period 8,000 years ago, soon after the last ice age.” Models had predicted that summer ice would disappear by century end. Instead “at current rates of shrinkage… this looks likely to happen some time between 2020 and 2050.”
