Process your emotions first. Get to a place where you feel positive about facing the problem. At the end of the day, global climate change is a good problem to face, like WW2 was a good challenge, and it decomposes into smaller problems, recursively, and there are real things you can do. Government's are the only actors that really matter; so it's time to get political. Understand the legislative and executive options; if there's something in-play, help out. Politics is, in general, labor intensive so volunteer. The more local the law, the more leverage you have - so don't ignore state and local law. If you work for a carbon intensive industry, quit. Triage your environmental concerns: landfills << carbon emission. Heck, nuclear waste << carbon emission. So don't get distracted by plastic straw bans or Fukushima/Chernobyl, etc. Politically, care about stopping: fracking, offshore drilling, pipeline investment, and (this one is important): carbon money in politics. Culturally, embrace a voluntary contraction: make more things locally, at home, using local material. Replace your PS5 (dream) with a treehouse; replace Spotify with your dad's guitar.
The only actors that matter are technologists developing better sources of energy generation, energy storage, and carbon capture are really the only thing that matters.
Isn't fracking a great source of natural gas? Isn't that much better than oil?
Fracking also increases the supply and therefore reduces the price of natural gas, which leads to more gas consumption and less investment in greener alternatives. Coupled with the ecological hazards that fracking itself imposes, I don't see how we can consider it a net positive.
Get out into nature, and enjoy her company.
