We are living in the darkest hour in human history so far. The science is clear and undisputed now: temperatures have risen as our greenhouse gas emissions have increased and are wreaking havoc on our planet… but it is going to get far, far worse. We are facing the end of civilization. This is an academic way of saying that humankind — billions of people — will face unlivable conditions and will devolve into starvation, slaughter and suffering on a global scale. This is not a distant future – millions of people are dying now because of climate destruction.
