Well, there’s also a town here in the US where there’s been a massive coal fire burning underground for decades, resulting in the evacuation of the town, etc..
Ah, yeah, here we go: http://en.wikipedia.org/wiki/Centralia,_Pennsylvania
Fun stuff - big smoking cracks in the ground, etc.
So yeah, next time you hear someone bragging about how much they’ve reduced their carbon fotprint by only showering on alternate Thursdays or something? Tell them that there’s a giant coal fire that’s likely been running since before they were born, pumping out more CO2 than they could ever possibly hope to accomplish in their lifetime, and will continue to do so for another 250 years…
