Global warming: It’s real and we did it

With the recent cold spell that has blanketed most of the United States, some people are expressing doubts about global warming. Two of the most prestigious scientific organizations in the world — The US National Academy of Sciences and The Royal Society of the UK — have just issued the booklet Climate Change: Evidence and Causes , in which they state in no uncertain terms the scientific basis for declaring that global warming IS occurring and that its causes ARE man-made.

The booklet even explains why a cold winter like the one we are currently experiencing doesn’t refute the reality of global warming. Using a Q&A format, it presents the information clearly, making its scientific case in terms that even a US congressman could understand. It is free and available for download in pdf format at www.nap.edu/catalog.php?record_id=18730.
