MARCLIMATEGRAPHS

Here are presented a collection of graphs and charts that were mostly created for use within Poole Agenda 21's newsletter by Dr Martin Rodger for the purpose of illustrating the progress of man-made climate change, often called Global Warming or AGW. The graphs are here kept up-to-date.
