Climate change is real and if you dont believe it, frankly you're a moron.
How much us humans are actually contributing to it is the real question. In my opinion we contribute very little on the scheme of things, if the figures I believe to be correct are actually correct.
Major climate occurances have always happened in cycles and always will. Theres nothng anyone can do to stop it. It would be like trying to stop the wind, ridiculous and a complete waste of time.
It doesn't really matter whether we caused it or not - it's a threat to our species, so we ought to try to do something to manage it.
Homo Sapiens have only been around for 190,000 years and in all that time the polar regions have been ice capped.
Lets just say for argument the earth is undergoing one of it's periodic climate shifts. Would we survive? That is the question.
You get retards saying things like "Warming doesn't matter, it was really hot during the dinosaur age".
Only
we're not reptiles! In the very warm Jurassic period, only cold blooded creatures really thrived, mammals struggled - while dinosaurs grew to a colossal size, mammals were no bigger than rats and were burrowing underground to keep cool.
It was only when the climate cooled that mammals became bigger and reptiles shrunk and have to stick to the warm parts of the world because they can't heat their blood by themselves.
We dominate the planet at the moment, but I'm not sure we'd evolve quickly enough (shrinking our mass) if the world heated. More likely we're looking at an extinction event for the majority.
The minority can always try to rely on technology to save them - but as the population shrinks that becomes problematic. Only about 1% have the brains to invent and develop technology, but because there's 6 billion of us, that 1% is big enough to invent the entire world's needs. Once you get population shrinkage, you shrink the number of brains, and all you need is for a few intelligent families to get wiped out for the rest of the population to struggle and slip into a dark age.
Really, trying to mitigate the climate now is the less risky option.
