Copenhagen Diagnosis - 7C (10.8F) Temperature Increase, 3.25 Meter Sea Level Rise Poss. By 2100

The planet could warm by seven degrees Celsius (10.8 degrees Fahrenheit) and sea levels could rise by more than a metre (3.25 feet) by 2100, scenarios that just two years ago were viewed as improbable, scientists said on Tuesday.

In the widest overview on global warming since a landmark report by the UN Intergovernmental Panel on Climate Change (IPCC) report in 2007, the authors said manoeuvering room for tackling the carbon crisis was now almost exhausted. The 64-page "Copenhagen Diagnosis" aims at the December 7-18 UN conference in Denmark, tasked with forging a planet-wide deal on greenhouse-gas emissions.

"This is a final scientific call for climate negotiators from 192 countries who must embark on the climate protection train in Copenhagen," said Hans Schellnhuber, director of Germany's Potsdam Institute for Climate Impact Research (PIK), which oversaw the paper. "They need to know the stark truth about global warming and the unprecedented risks involved," he said.

The scientists billed the summary as "an interim scientific evaluation" between the IPCC's Fourth Assessment Report, known as AR4, and its next big handbook, due in 2013. Several authors were part of that Nobel-winning group.

2. 2100 seems to me such an arbitrary number

Look, ALL the models have been off...this thing is happening at a faster feedback loop than we can gage or understand... we are talking about a PLANET that has never been changed like this before.

and while, yes, we have gone through periods of heating and cooling...this is faster because the man made chemicals and Co2 levels are off the charts. So what used to take a millennia, we could see in a couple decades, maybe even less.

So either we should be getting ready for a big flip and an ice age that will come up with surprising rapidity...OR we should all be investing in sunscreen and surfboards...
scenarios are a dime a dozen...TIME is what we are OUT OF.
