We have to keep up the fight for evidence-based science and policy.

The key thing to understand is that solar activity causes shifts in the jet stream with consequent changes in weather patterns and triggers processes that lead to storm formation.

The general trend in the last 4,000 years is that carbon dioxide and temperature have been moving against each other.

Polar bears did very well in the warmer times. They didn't die out at all; they didn't die out in the last 10,000 years, nor during the previous interglacial, nor the one before that. So, they're just used as a deceitful heartthrob; you know, to pluck your heartstrings because the polar bears might die out.

It's not the case that carbon dioxide drives temperatures. When you leave Ice Ages, it's the other way around: The temperatures go up first, and then carbon dioxide levels go up.

My view is that climate changes have happened in the last 80 years, that is, the world has got a little bit warmer, although not as warm as it has been in Medieval times, or the Bronze Age.
