The Climate Change 2007 volumes of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) provide the most comprehensive and balanced assessment of climate change available. This IPCC Working Group I report brings us completely up-to-date on the full range of scientific aspects of climate change. Written by the world's leading experts, the IPCC volumes will again prove to be invaluable for researchers, students, and policymakers, and will form the standard reference works for policy decisions for government and industry worldwide.
The Intergovernmental Panel on Climate Change (IPCC) is an intergovernmental body of the United Nations that is dedicated to providing the world with objective, scientific information relevant to understanding the scientific basis of the risk of human-induced climate change, its natural, political, and economic impacts and risks, and possible response options.
This is a book that I would only recommend to someone with a degree in science. The physical basis is exactly what it sounds like. This is the data and experiments studying general changes in climate. This is volume 3 and they also have a volume 1 for the general audience but this section is full of physics, chemistry, and geology. Being that I am studying to be an atmospheric chemist it was a must that I read the full report (like 1200 Pages) to know what I'm doing.
If you want to discuss the principles and findings in this book I am happy to do so but am not going to take time to write that much here
The 2007 IPCC report is the largest and most detailed summary of the current climate change science ever performed, involving scientific data from thousands of experts from all over the globe.

Step 1) read it. Step 2) understand it. Step 3) do something about the issue of climate change.
If you are having difficulty achieving step 2, you might want to stop whatever else you are doing, reach down, take a firm grip and pull your head out...
