Burning coal is generally known for being really bad for air quality. The ash is somewhat radioactive, and if there's any sulphur in the coal it'll cause acid rain. The exhaust from burning the coal nowadays ends up going through treatment to clean it up (remove sulphur and particulates), which is an added expense. In comparison, natural gas tends to be rather pure, so when burned it produces just carbon dioxide and water.

Natural gas is second-worst after coal among the major energy sources, releasing about half as much CO2.

Leaving coal in the ground is both necessary as well as supremely effective to stave off the next global catastrophe.

It also drastically reduces other emissions, some of which have been implicated in the current catastrophe.

As a cherry on top, it upsets coal magnates, a self-selected group uniquely qualified to entertain us with their misery.

Coal is probably the worst possible way to generate power at scale. People complain about nuclear power being dangerous but the air pollution from a coal power station kills people every single day.

(yes)

Oh, it's probably bad news for the coal plant owners.
