If you’re a US citizen, no matter where in the world, start by making sure you’re registered to vote. Many districts are gerrymandered, so you’ll want to register as the party that’s likely to win congressional and/or state legislative districts where you live, and vote in that party’s primary.
In addition to voting, you’ll want to influence politics beyond that. Your local races are a good place to start; cities and states control local land use and things like building codes.
To affect Congress, you’ll want to pick swing house districts or swing senate seats. Volunteer for a Democrat and donate accordingly.
For President, the reality is that the Biden/Harris administration has done far more than Trump would even consider, starting with the Inflation Reduction Act, for which Harris cast the tiebreaking vote in the Senate, and continuing through numerous executive actions. Getting involved in this race means volunteering, ideally for a climate-focused event like the Tuesday & Thursday phonebanking and if you can, donating to the Harris Victory Fund. If you’re giving really large amounts of money, and the logistics of it work, go to an in-person event and talk to the candidate or other official about climate:

There's a much more extensive list of what Biden has done here — but you can't get it outside the paywall because the last was started before the Washington Post started doing gift links.
Wow. I was going to copy and paste them into my comment, but then I saw there were 98 pages of accomplishments. Well done!
Here’s a link to get around the paywall: https://archive.is/2024.05.20-232047/https://www.washingtonpost.com/graphics/2021/climate-environment/biden-climate-environment-actions/
