Reading Snopes will give you plenty. Read the articles - and a lot of them use weasel-wording to push the result they want.

I don’t have the exact article on hand at the moment, but an example would be someone claiming that clear-cutting 1000 acres of trees would destroy [X]^3 of CO2 reduction; and then Snopes will “fact check” it by saying they aren’t cutting down 1000 acres of trees this year.
