"Air temperatures over the Arctic Ocean stayed well above average during November, partly because of continued heat release from the ocean to the atmosphere and partly because of a pattern of atmospheric circulation transporting warm air into the region."Evidence that Antarctica has warmed significantly over past 50 years (Climate Progress)The underwater permafrost is thawing and releasing methane (Climate Progress)Two trillion tons of land ice lost since 2003, rate of Greenland summer ice loss triples 2007 record (Climate Progress)From Russia with love (Gristmill)"Unfortunately, the greatest warming in 2008 came in the worst possible place for humanity -- the Siberian tundra. ... Siberian tundra contains probably the world's largest amount of carbon locked away in the permafrost. As it defrosts, much of the tundra's carbon would be released as methane, which is 20 times more potent a greenhouse gas than carbon dioxide. "

"In reality, the insurance business is all about dealing with uncertainties involving catastrophic outcomes. You factor together the scale of catastrophe with the probability it could occur. The larger the catastrophe, the less probable it needs to be to create the same level of economic risk. That's why an enormous risk, even though remote, could still be greater than a small risk that's virtually certain. You have to try to take them all into account."

Progressivism is pragmatism: Obama says “the facts demand bold action.” (Climate Progress)
A-propósito da escolha de um cientista para a equipa de Obama discute-se o conceito de pragmatismo:
"On that note, Hayes is absolutely on point: … pragmatism requires an openness to the possibility of radical solutions. It demands a skepticism not just toward the certainties of ideologues and dogmatism but also of elite consensus and the status quo. This is a definition of pragmatism that is in almost every way the opposite of its invocation among those in the establishment. For them, pragmatism means accepting the institutional forces that severely limit innovation and boldness; it means listening to the counsel of the Wise Men; it means not rocking the boat. ...When it comes to the climate crisis, the financial crisis, or the healthcare crisis, the facts demand bold action, and that means a bias toward “variability, initiative, innovation, departure from routine, experimentation,” in pragmatist John Dewey’s words."

The picture is unmistakeable - that Britain's climate is growing warmer at an unprecedented rate."
