Getting rid of bitcoin would be a start.

Let's instead get rid of private air travel. Has caused a pandemic and millions of deaths. And the emissions are very likely larger than those of Bitcoin. People can go on vacation by train instead. If you demand people use slow legacy money then I can demand slow legacy travel, ok? ;)

I see you're getting downvoted but maybe "get rid of" isn't the best approach. Certainly taxing air travel at a chunky rate would reduce unnecessary flights.

I frankly don't think this would make sense. Imagine explaining the people of a country, that they aren't allowed to fly to e.g. Mallorca anymore. The acceptance would be somewhere between low and zero.

Maybe private air travel in one country, e.g. from Munich to Berlin could be reduced, but not international flights without any resistance

Emissions from aviation contributes 3% to greenhouse gasses.

> This pact aims to keep the rise in global temperatures well below 2C this century and to pursue efforts to keep it under 1.5C.

It seems to me that continuing to communicate just the average temperature increase is a missed opportunity to engage with a greater portion of the population.

1.5 or 2 degrees do not seem like much, but once one understands that’s an average made out of much bigger positive and negative swings in temperature, one gets a much more dramatic picture.

I suspect focusing on the widening of the temperature range, rather than the average temperature change would work better with communications to the wider public

If some things "are irreversible on timescales of centuries to millennia" then really just going carbon neutral etc. sounds like a pretty weak approach as it would create costs now and large benefits only far in the future. Maybe this really needs geoengineering (and more spending on mitigation)?

Has any means of geoengineering been demonstrated as feasable?

Given our track record, it would probably be best for us to scale back our consumption while promoting re-forestation. Nature can likely heal itself far better than our wildest geoengineering ambitions.

That's a fairy big chunk. Especially if you take into account that globally almost nobody can afford to fly.
