Climate models and satellite observations both indicate that the total amount of water in the atmosphere will increase at a rate of 7% per kelvin of surface warming. However, the climate models predict that global precipitation will increase at a much slower rate of 1 to 3% per kelvin. A recent analysis of satellite observations does not support this prediction of a muted response of precipitation to global warming. Rather, the observations suggest that precipitation and total atmospheric water have increased at about the same rate over the past two decades.

On December 13, 2006, scientists warned that the Arctic ice is melting at a rate faster than was estimated. The ice has been shrinking steadily over the past 30 years, but now scientists say there's a possibility of an ice-free Arctic in the next few decades.

The conference of parties to the un climate convention in Nairobi went along predictable lines. In the 12 years of the convention, political rhetoric may not have changed much

Sudden global warming 55 million years ago provides evidence for high climate sensitivity to atmospheric CO2, but the source of the carbon remains enigmatic.

The source of the proposal was almost as remarkable as the idea itself.
