Science

So here are some good climate science websites
Real Climate
Nature Reports Climate Change
Hadley Centre
NOAA (US)
(The Royal Society website has been over-run by cutting edge web developers, and is now useless. C’est la vie…)

And on the “how to deal with denialists” then
a) ask yourself why you are so keen to wrangle with people who have their fingers in their ears – is it a way of not taking action yourself
b) never wrestle with a pig – you both get muddy, but the pig enjoys it

Skeptical Science – “Getting skeptical about global warming skepticism”
Climate Denial – George Marshall’s blog, not updated since Dec 09 (as of June 2010)

This – on “how to argue with a Global Warming denier” is fun.

And the youtube videos from “Climate Crock of the Week” are fantastic!
