Oh great. With in situ coal combustion, we can use all the coal, not just the readily mineable coal. Let's reproduce the CO2 increase from the end Permian extinction.
If they are already burning, and we can't or won't put them out, then why not? As of now, they are emitting CO2 and are also of no use.
Should we not use them out of spite of ourselves?
It's not a safe area to be around. The ground shifts, the air is death. The water is death. Really not worth it. There are some great videos on youtube about these places. They make clear why nobody lives around them.
