Three Scenarios for the Future of Climate Change, Elizabeth Kolbert, The New Yorker, October 5, 2020

Three Scenarios for the Future of Climate Change. What will the Earth look like thirty years from now? To a discomfiting extent, the future has already been written. There’s a great deal of inertia in the climate system; as a result, we’ve yet to experience the full effects of the CO2 that’s been emitted to date. No matter what happens during the next few decades, it’s pretty much guaranteed that glaciers and ice sheets will continue to melt, as temperatures and sea levels continue to rise. But to an extent that, depending on your perspective, is either heartening or horrifying, the future—and not just of the next several decades but of the next several millennia—hinges on actions that will be taken by the time today’s toddlers reach adulthood. What’s technically referred to as “dangerous anthropogenic interference with the climate system” and colloquially known as “catastrophe” is warming so dramatic that it’s apt to obliterate whole nations (such as the Marshall Islands and the Maldives) and destroy entire ecosystems (such as coral reefs).
