Greenhouse gasses going from lithosphere to atmosphere is the root cause of catastrophic anthropogenic global warming.

Spending energy on proof of work is not decreasing any fossil burning. It’s just not.

As an analogy, let’s say I want my students to get safe jobs instead of risking their lives as guillotine testers and tightrope dancers.

I take a quick glance at the jobs section and see that hmm, safe jobs seem to be paying better over the long run, if not in the short run.

So I take my students’ paychecks and burn the money in a big old firepit in the yard.
