Bitcoin's electricity use (or the electricity use of any other single application) is pretty much irrelevant when it comes to addressing climate change. Proof:

• Too much of what we does depends on electricity and has no even remotely feasible substitutes for it to be plausible to give up on electricity. In fact, switching more things to electricity, such as transportation and heating, is a large part of what we will have to do to address climate change.

• Therefore to address climate change we are going to have to switch to sources of electricity that are climate neutral, which cleans up Bitcoin (and all the other uses of electricity) from a climate standpoint.

EDIT: to clarify, of course Bitcoin's electricity use now has a climate impact. My point is that this will eventually be taken care of by the necessary switch to clean electricity for all our electricity production.

Until that happens we of course should be trying to clean up current electricity uses, but there are currently bigger fish to fry on that end than Bitcoin. To dismiss taking climate change plans seriously because most conversation is about things with bigger impact is not sensible.

If we take too long on the supply side and Bitcoin continues to grow it may move up the list to where it is one of those uses that we will need to address before we clean up the electricity supply.
