Ask HN: How to find work fighting climate breakdown?

I've been worried about global heating for most of my life. I've changed my own life massively in an attempt to reduce my footprint, but it's clear that individual action is essentially meaningless in terms of effecting desired outcomes.

Is there a way to find jobs/companies _specifically_ filtered for "what you do will fight climate breakdown", that would be accessible to someone in tech?

The closest I can come to are things like tools to improve the experience of using public transport or cycling, etc. but a green "Who's Hiring?" would be really useful. I've done what I can in my unpaid time but it just isn't as much as I could be.

We need a global response on the scale of WWII's mobilisation. There's a giant asteroid headed for Earth and we spend our days on meaningless fripperies hoping someone else will deal with it.
