I feel the same way - I’m somewhat skeptical partly because it’s good to be skeptical of most things, especially something that you can’t really see, but mostly because when I ask the climate change people what I should do in order to combat climate change, their first and only answer tends to be “vote democrat and never vote republican!” That being said, I still mostly do what (I think) the climate change people say I ought to do such as recycle, prefer energy efficient alternatives, and try to walk when I can. To the extent it doesn’t hurt us, we all might as well be “environmentally conscious” even if it turns out we didn’t actually have to be.
