Some changes people (in the US or elsewhere) might want to check into:

• See if your local electric utility has Green Power programs where you can elect to have your power come from renewables (via credits) for 2-5% of your bill/month extra
• If you own a home, consider making switches to more electrified stuff like: induction cookstoves v. natural gas, heat pumps v. AC units, power tools that have batteries and/or cables v. gasoline or diesel, adding solar panels to your roof or property (only costs ~$20k these days), etc.
• Start moving your pensions or stocks into greener index funds, or even consider adopting banks and credit unions that publicly disclose which projects and companies they invest your dollar in
• Consider buying your groceries from local farmer's markets or farms that have mail-to-your-door programs (aka CSAs or Community Supported Agriculture programs); this is a good resource to learn more about the farms near you
• Switch to non-red meat diets, and then after that switch to a vegetarian diet, and then after that switch to a vegan diet (all while consulting health professionals); this is a good resource on vegan diets if anyone is curious
• Consider choosing a Battery Electric Vehicle (BEV; 100% electric) or a Plug-in Hybrid Electric Vehicle (PHEV; 50/50 electric/gas) as your new car; this resource can steer you in the right direction
• Vote in primary elections where candidates prioritize climate action, then vote for them again in general elections when the time comes; this is a good resource to stay up on current civic events
• Buy clothing/shoes used, or if you need to buy new, look for the GOTS and OEKO-TEX labels to make sure what you're buying is organic, is ethical, and doesn't pollute local environments of where your clothes/shoes are made
