The Propublica map is pretty illustrative. Note that the total size of ideal US habitability doesn't change. If anything, it increases under the "extreme warming" scenario. But its shape is dramatically different. Key areas include the Dakotas, Montana, parts of the Basin & Range provinces, Modoc County in California - basically areas where virtually nobody lives now. Meanwhile densely populated parts of the American South, Texas, Florida, and the Southwest literally are becoming uninhabitable through wet bulb temperatures and sea level rise. The crop yield picture is complex too. It's not actually true that we're looking at 50-92% losses in California's central valley. We're looking at ~13-44% in the southern Central Valley, as well as the Imperial Valley (basically those areas irrigated with Colorado River water). Also looking at 6.5-15.8% increases in other regions of California like the Salinas Valley, Bay Area, far north coast, Modoc County. Central Oregon and Washington and the Great Lakes region stand to benefit as well - these are not areas with large current agricultural production. Expect upheaval. Humans don't do well when some people benefit and other people die for completely random reasons.
