There is a community at https://workonclimate.org/ focused on helping people find jobs related to climate. You can also look at https://climatevoice.org/, and look at how your employer is lobbying on climate. You can also look at climate bills/policy related to corporate disclosure at https://leginfo.legislature.ca.gov/faces/billAnalysisClient.... and https://www.sec.gov/comments/s7-10-22/s71022.htm to see which corporations are lobbying for or against strong climate policy, and try to work for those companies most supportive of strong climate policy.
