Could another large human institution dependent on complex models be headed for it’s ‘Lehman Bros’ moment? [...]

Global warming: a classic case of alarmism

In 2009 we are where the green arrow points, with temperature leveling off. The pattern suggests that the world has entered a period of slight cooling until about 2030.
