Earth warmest in 400 years -

400 years! (Or maybe 2,000 or more years.)

Weighing in on the highest profile debate about global warming, the nation's premier science policy body on Thursday voiced a "high level of confidence" that Earth is the hottest it has been in at least 400 years, and possibly even the last 2,000 years.
A panel convened by the National Research Council reached that conclusion in a broad review of scientific studies, reporting that the evidence indicates “recent warmth is unprecedented for at least the last 400 years.”>br> The panel of top climate scientists told lawmakers that the Earth is running a fever and that “human activities are responsible for much of the recent warming.”
They also considered the data reliable enough to conclude there were sharp spikes in carbon dioxide and methane, the two major greenhouse gases blamed for trapping heat in the atmosphere, beginning in the 20th century, after remaining fairly level for 12,000 years.
Between 1 A.D. and 1850, volcanic eruptions and solar fluctuations were the main causes of changes in greenhouse gas levels. But those temperature changes “were much less pronounced than the warming due to greenhouse gas” levels since the mid-19th century, the report said.
Gee I wonder if W is reconsidering his previous statements and will go see "An Inconvenient Truth?"

Am I nuts? His oil and automaker friends won't allow that.
