EarthTalk: Our Next President's Environmental Agenda - USA

The non-profit League of Conservation Voters (LCV), America's leading voice for environmental advocacy within electoral politics, would prefer to see Obama elected president given his environmental track record and plans for the future. While both candidates favor instituting a mandatory "cap-and-trade" program (whereby the federal government allows polluters to trade for the right to emit a reduced overall amount of greenhouse gases), Obama is for more strident cuts. He would like to see the U.S. reduce its greenhouse gas emissions by some 80 percent by 2050, while McCain supports only cutting back by 65 percent. Both candidates have authored legislation in the Senate designed to reduce greenhouse gas emissions, although no such bills have come close to passing.

One area where environmentalists take issue with McCain is his support for expanding the role of nuclear power in cutting fossil fuel use. Obama would rather bolster alternative energy sources like wind and solar power that do not have the nasty side effect of radioactive waste in need of storage and disposal.

"The limiting factor to more reliable climate predictions at higher resolution is not scientific ideas, but computational capacity to implement those ideas," said Jay Fein, NSF program director in NSF's Division of Atmospheric Sciences. "This project is an important step forward in providing the most useful scientifically-based climate change information to society for adapting to climate change."

Researchers once had assumed that climate can be predicted independently of weather, that is, with weather having no impact on climate prediction. Now they're finding that weather has a profound impact on climate, a result that's integral to the drive to improve weather and climate predictions and climate change projections.
