May 2012, the 327th consecutive month in which thetemperature of the entire globe exceeded the 20th-century average, the odds of which occurring bysimple chance were 3.7 x 10-99, a number

considerably larger than the number of stars in theuniverse.

John Fullerton, a former managing director at JPMorgan who now runs the Capital Institute, calculatesthat at today's market value, those 2,795 gigatons ofcarbon emissions are worth about $27 trillion. Which is

to say, if you paid attention to the scientists and kept 80percent of it underground, you'd be writing off $20trillion in assets.
