So now our denier friends have convinced themselves that climate is changing and it is us that is changing it, but guess what? Impacts will be minimal! Err what? and they were doing so well! Strap in to learn about the impacts we have already seen, those we might well see and those we sure as hell hopefully won't end up seeing and hopefully we'll demonstrate to you that this breed of deniers/skeptics are just as detached from reality as those 'climate change isn't happening' more basic types!

The world is imperilled, yet many are STILL questioning the science. Are you in a dream? No, reality appears to be stranger than fiction. Hence the question: Why so much denial/skepticism anyway?

Rounding off our recent 3 part series on why it is (unfortunately) us. Skeptics/denialists have a problems with the CO2 explanation, if they even admit it's increasing then they think it's insignificant. Or if it's significant then its increase is natural. There is much shifting of the goalposts, but no matter, here we explain why they're wrong, wrong and wrong again!
