If I may be slightly off-topic, I have a similar question I still haven't found a satisfying answer to:

What's the best way to spend my work time towards climate efforts? (i.e: I have useful professional skills, how can I help in a serious way?)

For example, is there anything like a job board focus on companies/organizations/scientist labs/other structures working on stuff related to climate change? As a software engineer, I would greatly prefer to work for a group that has some positive impact on the situation, and I would expect that there is a demand for better tools, platforms, etc that can help research or whatever is the important thing to do.
