NYT: NOAA map details US climate change over last century

The map produced by the National Oceanic and Atmospheric Administration shows that virtually all of the U.S. has higher average temperatures than 100 years ago. The precipitation data shows where rainfall averages have increased (East Tennessee and most of the Appalachian Mountains and their adjacent foothills and valleys) and where they fluctuated beyond average (California and the Southwest). Some of the data predates the regular government weather and climate record-keeping that began 90 years ago.

"Because the normals have been produced since 1930, they also say a lot about the weather over a much longer term. That is, they show how the climate has changed in the United States, as it has across the world, as a result of emissions of heat-trapping gases over more than a century."
