Portsmouth Climate Action Network

The now famous Global Warming hockey stick graph produced by Michael Manns scientific team at Penn State University has been revived using new data looking further back in time. Many critics of the graph have suggested that the Medieval period contradicted Global Warming predictions, however new data has been investigated that reinforces the relative accuracy of the original graph. 1,200 new proxy data records go back over a 2000 year period and back up the original graph.

Michael Mann has also co-authored a book with Lee Kump. Called 'Dire Predictions: Understanding Global Warming', the book has had the help of Dorling and Kindersley graphics specialists, to make the Climate Change data more palatable to students and the general public. The book should be available from most book retailers in the UK, including Amazon.
