Many of us don’t want to uproot everything - at substantial effort and cost - for unclear or negligible upside. USA is only at 13% of global emissions. And radically overhauling everything, as opposed to incentivizing greener tech over time, is unlikely to move the temperature much if at all. China will not play ball. The developing world will not play ball.

If we were dead serious about this as a civilization threat, we would start building as much nuclear as possible

USA is only at 13% if you only account for emissions by the USA. If you count the CO2 emissions the USA paid for then it is more than double that of China.

The whining about "uprooting everything" is such a cheap cop out. The US doesn't suddenly grind to a halt when oil prices are higher, or when production of goods moves back from China to Detroit.

Uproot everything? There's only 2 significant direct disruptions that would be felt directly by the population: getting an electric vehicle and stove/oven. They both have cost but that can be (and is) transitioned over time and the economic burden can be subsidized.

I agree that nuclear would be great but unfortunately it doesn't seem to be cost effective. Even my pet notion, SMRs, seem to be unable to cut it. NuScale has promise but even they seem to be unable to compete with solar and wind.

Geothermal is also waiting for us -- I hear there's a bit of extra heat in the Yellowstone region.

The key thing is that our political leadership is currently owned by the fossil fuel industry and they don't want to let go of their massive profits. They've also managed to politicize the issue to such a degree that a major political party (and its membership) has no interest in addressing this and has convinced the base that it's a hoax. That's as political as I'll get here -- is to note stated positions and policies.

The US has (will) spent $6T on two wars that had no reason or value. We have plenty of money to spend -- it's just a matter of spending it wisely.

Another note: we can't expect China or the developing world to play ball if we don't lead by example.
