Climate Change Science: Resources part 1

Following on from our successful Climate Change Q and A, here are some resources where you can find out more about climate change science, the effects climate change is having now and the predictions for the future.

I'll be splitting the resources post into two parts. This (part 1) will contain links to websites with lots of information on climate change. Part two will be links to specific graphs and figures on areas of climate science. I'll also add some links to the sidebar on the blog.

Websites with information of climate change:

NASA - climate change. Brief easy to understand descriptions of evidence, causes, effects etc.
UK Met office - Your guide to climate change. Lots of information here.
RealClimate - "Start here". RealClimate is a website/blog run by climate scientists, the Start Here page is full of links to climate change information graded by your amount of knowledge (from complete beginner to lay informed)
Coby Becks' - How to talk to a climate skeptic. Debunks common myths about climate change.

IPCC 2007 (AR4) Report - The consensus science on global warming.
There are three long working group reports and a synthesis report tying it all together. Mostly available as PDFs only.
Start with the Synthesis Report's: Summary for Policy Markers (SPM) which is written for a lay audience. Then try the synthesis report itself or the SPM from the individual working group reports.
The IPCC does provide online FAQ's. These help to explain a lot about the climate and climate change.

NASA - Temperature Record (GISTEMP) - Lots of informative graphs showing temperature changes since the instrumental record began.

Climate Denial Crock of the Week - Peter Sinclair's produces short, easy to understand Youtube videos to explain climate science and rebut deniers.

RealClimate and Skeptical Science. Two websites that provide commentary on the scientific literature so that it is understandable to an informed lay audience. RealClimate also allows you ask working climate scientists questions, however it is recommended you gain a reasonable understand of climate science first. Their Start Here function can help you with this.

Update 25.11.09
A group of leading climate scientists have just released the "The Copenhagen Diagnosis" which updates the climate science since the IPCC AR4 in 2007. This report is written for a non-technical audience and be downloaded or read online.


Enjoy!

PS: I have tried to keep this list brief and link only some of the most reputable sites. However if you think there are other sites that deserve to be on this list please leave a comment.
