Looking to learn more about climate change now that most of the lift-served terrain is closed for the season? A great place to start is this very readable report on climate change, “Understanding and Responding to Climate Change” by the National Academy of Sciences (NAS) Board on Atmospheric Sciences and Climate. If you have a scientific background and want to read peer-reviewed work that is published in the scientific literature, the Intergovernmental Panel on Climate Change (IPCC) provides in-depth reports that reflect a range of views, expertise and wide geographical coverage. IPCC materials aim to be neutral with respect to policy. In addition, the US Environmental Protection Agency has a State of Climate Change Knowledge web page and the US Global Change Research Program created by Congress in 1990 has an on-line climate change library.
