For what it is worth. As I don't want to turn this into an ugly argument.
Yes. I think man contributes to obvious current climate change.
I also think climate change happens naturally as to not do so would be dim. The question is how much mans influence has on these changes.
And frankly again. I do not know. The fact you think your awesome enough to know for sure is great ...... Big ups to you.
Not pumping bad stuff out is a good thing either way, as it also has environmental upsides, but the 4-5 big players aren't going to stop doing it, and without them she is a bit of a dead end.
Oh Jeez, there is no question about the massive human influence on climate change. Read the science and learn or shut up.
