Last month the White House released a landmark report called Global Climate Change Impacts in the United States. The report was historic in that it was the first statement by the United States government acknowledging the impact of climate change on the American people.
It is also historic in that it is one of the first (and one of the best) accountings of the specific types of impacts climate change will bring about region by region.
The report finds that there is already a clear link between climate warming trends in the past two decades in six impact categories -- water, energy, transportation, agriculture, human health and ecosystems.
The World Wildlife Fund just put together a nifty interactive map that lists some of the predicted impacts by region.
Here's a video form the White House about the report:
