Perhaps, if we look only at the species that we know have already gone fully extinct. And of course, if there are more than a handful of any species, it technically could recover. But driving looking only through the rear-view mirror is a plan for disaster. We must also look at the declines in existing species, like 80% over just a few decades of insects, many types of plants, birds, fish, and more. These are massive and rapid declines, and there is little in the way of trends that are turning in their favor. In fact, more than climate change, habitat destruction and over-fishing/over-grazing/over-extraction may destroy many species far before climate change would undo them. Moreover, the actual measurements of climate change indicate that it is changing far MORE rapidly than the models. Plus, we're apparently blowing right through a number of tipping points, including arctic albedo (from sea ice completely melting where it never did before, and the last few inches of ice no longer reflecting white), gigatons of methane starting to release from the thawing permafrost, and several other feed-forward disasters. Plus, few are looking at what point the food web breaks. Once that happens (and no one knows if we first lose the bees, the plankton, or some other critical link, or a zoonotic pandemic where we don't get as lucky as the last time) we're so far beyond screwed.... and so is the ecosystem
