Natural gas is terrible, but arguably less terrible than coal which aside from CO2 spews out a plethora of other nasty compounds.

One small plus for coal is that it doesn't leak. With better satellite observation now, we're finding out how underreported the emissions of methane from natural gas extraction were.

Of course coal "leaks" .. it's a major issue worldwide.

Coal mines also leak methane.
