Underground Fires

Dan Cray reports in Time Magazine that “Internationaly, thousands of underground coal fires are burning on every continent except Antartica.”
It also reports “Anupma Prakash, a university of Alaska-Fairbanks geologist who maps fires, calls them ‘a worldwide catastrophe with no geographic territory, and if we don’t take care of them they are going to take a toll on us.’
The underground fires are consuming at least 10 million tons of coal annually.
