Probably nothing that we have ever managed to do quite equals the basic undermining of the physical stability of the planet on which most of the world's poor people depend.
Bill McKibbenThe essential thing we need to understand is that the climate crisis is not some future threat, but a very present peril, the biggest one humans have ever encountered. Until we understand that, we'll dawdle.
Bill McKibbenWe've been given a warning by science, and a wake-up call by nature; it is up to us now to heed them.
Bill McKibbenAll the things that we've done as a species have had a limited scope. We're talking about melting the ice caps, raising the level of the seas dramatically, changing the distribution of every other species on Earth, perhaps wiping out one-third or half of them. The changes at work are geologic in scale. The level of change required to deal with it is enormous, too. It will require change in every country. It will require a degree of global cooperation that we haven't seen before.
