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.
Piers CorbynIt'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.
Piers CorbynThe 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.
