Global Warming’s Terrifying New Math

Bill McKibben, Rolling Stone

Three key numbers you need to know when discussing climate change impacts and action: 2° Celsius, 565 Gigatons, and 2,795 Gigatons.

Al Gore and David Blood, The Wall Street Journal

How the Carbon Bubble Will Pop

Washington Post

It’s now clear that any sort of solution to the climate change crisis that requires action from Congress — where many members of one party refuse to admit the problem exists at all — is pretty much impossible. But there are plenty of ways Obama can use executive action — not to solve the problem, perhaps, but to forestall doom as long as possible.

The IEA(s World Energy Outlook (2012 edition) estimated that in order to have a 50% chance of limiting the rise in global temperatures to 2ºC, only a third of current fossil fuel reserves can be burned before 2050. The balance could be regarded as unburnable.

What A Carbon-Constrained Future Could Mean for Oil Companies’ Creditworthiness [PDF]

Standard & Poor’s Rating Service

Financial models that use past performance and creditworthiness may be insufficient to guide investors on the effects of future carbon constraints on the oil sector.
