5 reasons climate change is a strong choice, but not always the best:
1/8
1) We think that climate change is much less likely to cause human extinction (< .01% chance in the next century) vs other anthropogenic risks like pandemics or AI (@tobyordoxford estimates total existential risk in the next 100 years as 1 in 6).
2/8
2) Climate change might have significant indirect effects.
It could increase instability, increase the chances of great power conflict, cause migration crises… and these could exacerbate other existential risks.
So it’s an important risk factor.
3/8
3) On the other hand, all risks have indirect effects.
E.g. a pandemic could also increase instability and the chances of conflict.
It’s not clear the indirect effects of climate change are larger than the indirect effects of other problems facing humanity.
4/8
4) Climate change is far less neglected than other major global issues.
Current spending is over $640 billion a year. Compare that to ~$100 million for AI safety.
There may be some important neglected areas though, like specific tech (e.g. hot rock geothermal).
5/8
5) But climate change does seem more tractable than other risks.
There’s a clear measure of success (how much greenhouse gas we are emitting) and lots of experience on what works. That's a reason to work on it.
