A new book out The Climate Casino by economist William Nordhaus, Sterling Professor of Economics at Yale. Quote: Like many other experts, he sees a drastic reduction in the burning of coal as the obvious step in reducing greenhouse gases. He urges that we accomplish that by enacting a tax on carbon dioxide emissions of, say, $25 a ton for openers — or the equivalent in exchangeable pollution credits in the system known as cap and trade. And, he says, we need to do it right now. In particular, he frets about four tipping points: the collapse of the large ice sheets of Greenland and West Antarctica; large-scale changes in ocean circulation (possibly reversing the Gulf Stream); situations when warmth prompts more warmth (say, by the thawing of frozen methane); and the possibility of a warming trigger that may double the Earth’s temperature increase, to six degrees Celsius. (Even three degrees is now considered an unthinkable extreme.) unquote. nytimes/2013/12/01/business/climate-casino-an-overview-of-global-warming.html?ref=science&_r=0
