This Daily Telegraph report on the forthcoming IPCC report says it all:

Scientists are now overwhelmingly confident that mankind is to blame for the warming of the global climate observed since the industrial revolution, a UN report will conclude today.

The exact phrasing of the report by the Intergovernmental Panel on Climate Change was still being negotiated by scientists behind locked doors in the Unesco building in Paris last night.

My bold. Negotiated? Science advances by negotiation? Let’s try negptiating about whether or not the speed of light is a constant throughout the universe. Let’s try negotiating about string theory. Let’s try negotiating to find a cure for cancer.

The caption to the accompanying picture of a smokestack reads:

Factory smoke: climate change is man-made. The world’s temperature has risen 1.26°F since the industrial era started

As I last posted, such an increase when emerging from a cool period is within the bounds of previous natural temperature rises.
