Just a couple of quickies tonight. David Roberts at Grist links us to an analysis that confirms that Peak Oil conjecture is pretty much right on and we've got maybe 4 years before we're sucking it big time. . . . And before you log off, Joseph Romm updates us on the importance of tipping points and nonlinearity in the model-building world (which doesn't handle them well and will likely underestimate coming impact as a result) and in the real world (which doesn't handle them well and will likely underestimate coming impact as a result).
