21. Yes, but that should have caused a runaway increase to 10 degrees.

According to what they think happened in the Permian.

We're obviously going to have a very different planet when the methane is released. As powerful a greenhouse gas as methane is, there is some good news about it: unlike CO2, it isn't stable. It will react and "burn." Unfortunately, when it does, it produces Co2 and water vapor. Still, that's not as bad as methane.

Therefore, the greatest effect of methane is short lived. Meaning, with a big increase, you'll probably get broiling temperatures immediately which will drop back to simply "hot" in a year or two.
