Well this "nihilistic hysteria" is the truth, whether you like it or not. And yes, the sky is falling thanks to our discovery of fossil fuels.
I can feel climate change happening just by stepping outside. I can see it in the brown lawns that used to be green just a few months ago. There is no longer any snow on our mountaintops here. I can see the denial being repeated in my own family by saying Global Warming is a hoax. The people living in Kiribati and the Maldives will be without homes ten years from now. Florida will be swallowed up by the Atlantic soon after that, and the rest of the American South will be too hot to live on. The marine food chain is being destroyed from the ground up due to acidification of the oceans; the coral reefs are bleaching before our eyes. The rising sea levels are happening NOW, and are quickly wiping out whatever fresh water we have left. THIS year will promise to be one of the hottest years on record, only to surpassed by next year: the top ten hottest years record were all in the last decade. Extinction rates are the fastest they have ever been since the dinosaurs were wiped out 65 million years ago.
WE CAN'T SURVIVE WITHOUT FOOD AND WATER YET WE DESTROYING OUR FOOD AND WATER.
ON A SCALE OF 1 TO 10 WE ARE AT 11 AND WE'RE NOT EVEN TO THE WORST OF IT.
