Yes. That's it. But do we adapt physically, like raise our body temperature tolerance, or geographically, like nomads, move to Alaska, NWT, Greenland, Siberia, Anartica, or move our cities to higher ground, let some just sink (didn't we try that with NO but it only cost more), or technologically, like CO2 capture, nore nuclear plants, build tidal dams, more air conditioning, etc, etc. Lastly, doing nothing.
BTW Do we have cost estimates for all of those options? Could doing nothing have the highest cost of all? Becoming extinct?
Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."
