I do find it extraordinary that people call carbon dioxide a pollutant because as I understand it, you know, plants don’t grow without carbon dioxide […] I’ve often asked the question: what about sunspot activity? Surely, historically, when it comes to the planet heating up and cooling down, sunspot activity is a factor, and yet that doesn’t get talked about. And then of course we’ve got volcano particularly underwater volcanoes in the Pacific Ocean and from what I can understand it only 3% of carbon dioxide that’s in our atmosphere is produced by man.
