Which companies or industries are most vulnerable to the physical, regulatory, or reputational risks of climate change and will likely go under in the next decade?

And no, oil companies are not an option because they seem too resilient and diversified.
If you really have an interest in climate change, the Department of Energy is well funded and staffing up.
Your best bet is to find companies that can adapt and thrive in a climate change environment. Look into the inflation reduction act passed last year by the Biden administration. There are billions in incentives for climate change businesses. Companies that are created because of the incentives are likely to do well.
