The argument from consequences
If A is true then it implies, causes, or creates, B.
B is, either subjectively or objectively, bad, immoral, or undesirable.
Therefore, A is false.
The existence of gravity would make falling from a height onto a hard surface unpleasant, therefore gravity cannot exist.
Reducing greenhouse gas emissions would require policies we don't like, therefore anthropogenic greenhouse gasses don't have any effect on the climate.
sadly this foolish argument is too common..
