How much misinformation can the Union of Concerned Scientists pack into one report?
Report Warns of a Much Warmer Northeast

People in Philadelphia would swelter through as many as 30 days with temperatures higher than 100 degrees each summer.The Northeastern ski industry, except for western Maine, would probably go out of business. And spruce and hemlock forests — as well as songbirds such as the Baltimore oriole — would all but disappear from New Jersey to the Canadian border.
These are among the conclusions of a two-year study by the public interest group Union of Concerned Scientists on the effects of global warming in the Northeast if current greenhouse gas emission patterns worldwide continue unabated. Winters would be on average 8 to 12 degrees higher by the end of the century, and summers 6 to 14 degrees higher.

The frequency of 100 degree days in Pennsylvania has dropped dramatically since the 1930’s, and is consistently much lower now than it was prior to 1940. The eight years from 2003 to 2010 had no 100 degree days, which was the longest such period in a century.

The claims of large temperature increases have no scientific basis whatsoever. I have done software development of radiative transfer models (the models which calculate the greenhouse effect) for the US government, and they provide no indication of large temperature increases in the future due to increasing CO2.
The Union of Concerned Scientists is simply making “facts” up.
