@sarajw @ohhelloana @matthiasott there are great books like Project Drawdown or Speed and Scale that talk about the parts of our economy and society that need to change. Find a way to work on them. Get specific.
Climatebase has climate-related jobs. There are tech volunteer opportunities. You can contribute to open source projects like the ones at Open Earth Foundation.
As someone who works in climate, I can say clearly: we need your time, money, and attention. There is a lot of work to do.
