Or live wisely so you have the financial means and health to move you and your family elsewhere when need arrives, probably in our lifetimes for 80% of the world.
Right. That's arguably the prudent take on "party hearty". There's always the tension between "do fun stuff now when you can enjoy it most" and "save for later when you'll have more free time and less likely income".
Ah understood. You were looking at the national level with countries like China and Russia "party[ing] hearty" by not significantly curbing C02 emissions. Those individuals who benefit directly from oil and coal (as they do in the US) will extract gains and use it to pad offshore bank accounts. Meanwhile the rest of us should take a prudent life and be prepared for shocks ahead (like land and cost of living soaring in climate-friendly cities). On a more personal level, ideally savers find ways to extract more late-life enjoyment out of their deferred-enjoyment lifestyles.
The US is still partying hard. At least, relative to much of Western Europe. Much of Eastern Europe still has too much inefficient Soviet-era infrastructure. And yes, China has had slack in most climate agreements.
