A More Credible Justification Of Human Hubris?

"If Ruddiman's work demonstrates major flaws in the politically correct theories of recent human responsibility for climate change, it by no means should leave us complacent. Human civilization has flourished for the last 8000 years precisely because of a benign and stable climate in many parts of the world, a climate which was the result (if Ruddman's hypothesis is correct) of human activity (warming) balanced against the natural cycles of the earth in its orbit around the sun (at present, cooling). But Ruddiman notes that the human side of the equation has accelerated. CO2 levels in 2006 have reached levels the earth hasn't seen since the age of the dinosaurs. We are, Ruddiman says, heading into terra incognita. His work has, however, given new insights into climate change and, as his hypothesis is evaluated in detail, may help to inform policy decisions around the world."
