I think the title says it all "All those Scientists". All those thousands of intelligent, highly educated people, experts in their fields, who have spent billions of hours examining the data, testing theories and extrapolating alternatives might, just possibly, not be absolutely 100% correct in their predictions. So we should do nothing and hope they’re not right.
The question should be, what’s so wrong with reducing carbon dioxide output? What’s being called for is an increase in efficiency and a reduction in reliance on limited resources. It’s a winning combination for everyone and a great way to alleviate poverty. Even without global warming this should be the aim of every person on the planet. Or do the deniers not want to see poorer people leapfrog ahead of them into the future?
