The World of Tomorrow

Imagine that tomorrow, we discovered a world orbiting the Sun directly opposite of the Earth. It has the same inclination and the same size moon. It has an average temperature of 65 degrees Fahrenheit, with oceans covering 73% of the world, and ice covering 7% of the world. It is teaming with life, although there are no humans or similar species.

It would be a miracle, no? We would definitely stop planning to go to Mars, with its average temperature of -81 degrees Fahrenheit. 

The mirror Earth described above is what our world will be under climate change (except for the no-humans part - there will be lots of humans still). 

Be honest: wouldn't it be better if there was no more Florida?

Again, I don't mean to imply that climate change is not serious. It is, but not because the world will be "uninhabitable" (1, 2). Climate change will cause a lot of suffering because we have set up our civilizations under the previous climate - living along coasts and river deltas, growing certain crops certain places, suppressing fires that have normally been a part of the ecosystem, etc. If we actually took suffering seriously, we would be hard at work adjusting civilization to the coming new norms. But instead, many of us just keep demanding zero emissions while emissions continue to rise.

Meanwhile, Biden has passed the nation's largest climate investment ever

PS: You want uninhabitable? Check out Snowball Earth.

PPS: Tweeting about “climate emergency” rather than “climate change” makes you seem less credible.
