Sounds like you are in a similar place to me. I recently became a father and I feel that I need to work on this problem the best way I can. I have my little startup and I expect to keep running that for another few years but I have started a background thread in my head looking into how I can best apply my particular skillset to helping tackle climate change.

I had a chat with a woman named Laurie McGinley who coaches people in that situation and she gave me a bunch of resources that I am slowly consuming. I can highly recommend talking to her if you are considering it as well. https://vialucent.com/
