Evidence is here.

And if you're thinking that there is a massive secret conspiracy among tens of thousands of scientists worldwide, please consider which is more likely: a vast international conspiracy among scientists or a small-scale misinformation campaign among a few dozen oil companies whose tens (if not hundreds) of billions in annual profit depends on fossil fuel consumption. Much like cigarette companies in the 60's through 80's.
Please also consider the large number of energy companies, including Exxon Mobil and BP, who are committed to maintaining Paris Accord limits, and many more https://cei.org/blog/ten-major-energ...-don%E2%80%99t that support a deal that will limit warming to 2 degrees.
