"The evidence of climate change is growing all around us."
Nick Sundt writes at the World Wildlife Fund's climate blog as an introduction to his summary of the findings of the U.S. Environmental Protection Agency's (EPA) new report: Climate Change Indicators in the U.S. Sundt's summary is a clear and concise compilation of the data, presented in the following categories:
Greenhouse Gases
Weather and Climate
Oceans
Snow and Ice
Society and Ecosystems
For each category of data Sundt provides links to smaller PDF sections of the full report. (If you'd like to download the whole thing, a PDF is available online from the U.S. EPA here. Additionally, a short 4-page summary of the key findings is available as a PDF here.)
The full 80-page report is filled with informative charts, graphs, maps and pictures. Sundt reproduces a compelling selection of eight images. Here is a preview of three:
Rate of Temperature Change in the United States, 1901–2008. This figure shows how average air temperatures have changed in different parts of the United States since the early 20th century (since 1901 for the lower 48 states, 1905 for Hawaii, and 1918 for Alaska). [For more information on this indicator see "U.S. and Global Temperature," p 22-23 in Climate Change Indicators in the United States [PDF], April 2010]

Rate of Precipitation Change in the United States, 1901–2008. This figure shows how the amount of precipitation has changed in different parts of the United States since the early 20th century (since 1901 for the lower 48 states; since 1905 for Hawaii). Alaska is not shown because of limited data coverage.

Trends in April Snowpack in the Western United States and Canada, 1950–2000. This map shows trends in snow water equivalent in the western United States and part of Canada. Negative trends are shown by red circles and positive trends by blue.
