A team of British researchers released a study demonstrating that even if you can grow plenty of food, the transportation system that distributes it … - Bill McKibben

The expected effects of a sea-level rise typify the many consequences of a global warming. On the one hand, they are so big we literally can't understand them. If there is a significant polar melting, the Earth's center of gravity will shift, tipping the globe in such a way that the sea level might actually drop at Cape Horn and along the coast of Iceland—I read this in a recent EPA report and found that I didn't really understand what it meant to tip the Earth, through I was awed by the idea. On the other hand, the changes ultimately acquire a quite personal dimension: Should I put in a wall in front of my house? Does this taste salty to you? And, most telling of all, the human response to the problems, the utterly natural human attempt to preserve the old natural way of life in this postnatural world, creates entirely new consequences. The ocean rises; I build a wall; the marsh dies, and, with it, the fish.

Fair or not, boomers and the Silent Generation have about 70% of the country’s money, compared with about 5% for millennials. So if you want to push around Washington, or Wall Street, or your state capital, it helps to have some people with hairlines like mine.

So now we have some sense of what it’s like: a full-on global-scale crisis, one that disrupts everything. Normal life—shopping for food, holding a wedding, going to work, seeing your parents—shifts dramatically. The world feels different, with every assumption about safety and predictability upended. Will you have a job? Will you die? Will you ever ride a subway again, or take a plane? It’s unlike anything we’ve ever seen. The upheaval that has been caused by Covid-19 is also very much a harbinger of global warming. Because humans have fundamentally altered the physical workings of planet Earth, this is going to be a century of crises, many of them more dangerous than what we’re living through now. The main question is whether we’ll be able to hold the rise in temperature to a point where we can, at great expense and suffering, deal with those crises coherently, or whether they will overwhelm the coping abilities of our civilization... The pandemic provides some useful sense of scale—some sense of how much we’re going to have to change to meet the climate challenge.
