I am amused by the optimism of these responses. Nobody is concerned that if we end up with cheap nuclear fusion that humanity won’t use a lot more of it? Would humans stop building resorts in deserts?



Deserts are a wonderful place for resorts, assuming it is man made desert (like the Sahara) and infinite energy to desalinate and recycle water in an ecologically sound way.

We just aren't to that point yet.


I am completely a proponent of humanity using cheap energy to elevate our standard of living to ridiculous levels. I’m just wondering what we will do with the waste heat. I cannot believe that we will limit ourselves to current levels of consumption.


I was unaware that the Sahara was man-made.


Yep; we overfarmed the crap out of it in prehistoric times, apparently.


Given that the desert formed > 2 mya and human agriculture originated ~12 kya, this seems unlikely.

Modern humans themselves originated only 200 kya.

Article from 2018 referencing the study I was referring to:

Right.

We do know that the climate of the Sahara differed and it was grasslands in portions for a time.

But it wasn't farmed (your own article notes that the seeds found were wild), and the processes which re-asserted the pre-existing desert landscape were not human-induced.
