Actually the best things you can do are

1: join a climate lobbying group (I joined this non-partisan group : https://citizensclimatelobby.org/)

2: contact your congressperson and tell them you support carbon tax and dividend

3: contact your congressperson and tell them you support raising taxes to subsidize green investment and end fossil fuel subsidies

4: vote. Locally and federally and often.

Any “you stuff” is way after the above in terms of efficacy.
