Remember when CO2 was going to kill us all, and the Obama administration was going to save us?

[June 16, 2009] Global climate change impacts in the United States: Manhattan floods, Chicago heatwaves and withering Californian vines: how scientists see the US in 75 years | Environment | guardian.co.uk

The Obama administration's long-awaited scientific report on the sweeping and life-altering consequences of a failure to act on global warming – Global climate change impacts in the United States – is released today.

It provides the most detailed picture to date of the impacts on the US in the worst case scenarios, when no action is taken to cut emissions. Examples include: floods in lower Manhattan; a quadrupling of heatwave deaths in Chicago; withering on the vineyards of California; the disappearance of wildflowers from the slopes of the Rockies; the extinction of Alaska's wild polar bears in the next 75 years.

The winter snow season could be cut in half in southern New York, Vermont, New Hampshire and Maine — maybe as short as a week or two, under the higher emissions scenario. This would destroy winter traditions like skiing and skating and outdoor ponds. [Funny, I don't see any predictions of record snowfalls here.] Native cranberries and blueberries would disappear; dairy herds, the biggest agricultural industry, would decline under the higher emissions scenario.

Warming over this century is projected to be considerably greater than over the last century. The global average temperature since 1900 has risen by about 1.5ºF. By 2100, it is projected to rise another 2 to 10ºF. The U.S. average temperature has risen by a comparable amount and is very likely to rise more than the global average over this century, with some variation from place to place.
