Climate Warming Map

Caption

This map shows the observed difference between the average annual US temperatures (degrees F) for this century (2000 to 2009) and those of the last century (1900 to 1999). It is clear that the US has been much warmer in this century than the last, particularly in the West, and even more so in the Southwest and headwaters of the Colorado River.
