Hello Mr. Firth, I am completely well educated in earth sciences, thank you very much. You quote data released by NASA, they are in government pay, they use the right buzz words in their research to secure American government funding, and hence they are not to be believed. I have no confidence in the Stanford Solar Centre, again they are government funded. I suggest you educate yourself in two poignant ways;

1: Study geologic history, and not astronomy, as it is the earth that we are more concerned with. The sun is getting hotter as it grows older. This debate is about Giai's ability to regulate itself much more than a star's evolution.
2: Lobby your government and ask them why they will not sign to Kyoto.
