Did you know that there are hundreds (and maybe even thousands) of underground coal fires burning out of control? These fires can occur naturally, but most of them are caused by mining activity or industrial accidents near coal seams. These coal fires can cause dangerous subsidence, air pollution, and poisoning of the water table, all while consuming a valuable natural resource.
Concern and action is needed… because of the environmental impact — especially of mega-fires burning in India, China and elsewhere in Asia. One coal fire in northern China, for instance, is burning over an area more than 3,000 miles wide and almost 450 miles long.

Underground coal fires are extremely difficult to put out once they start burning. They burn so hot that even pouring water on them will feed the flames (at extreme temperatures, water breaks down into hydrogen and oxygen gas). Coal is inherently unstable and will self ignite - that means that old abandoned mines are time bombs waiting to go off and all the tunnels act as a ventilation system!

Uncontrolled coal fires are a worldwide problem and they produce significant amounts of greenhouse gas:
Estimates vary, but some scientists believe that anywhere from 20 million to 200 million tons burn [in China] each year, producing as much carbon dioxide as about 1 percent of the total carbon dioxide from fossil fuels burned on earth… India, where large scale mining began more than a century ago, accounts for the world’s greatest concentration of them.
Underground coal fires happen in the US too - check out this video about Pennsylvania coal mining. In Centralia, PA, underground fires have been burning since the 60’s! If you can come up with a way to put these fires out, I suspect that the MacArthur Foundation will come and knock down your door!

Here’s an interesting statistic that I had not read about previously!
The editorial section of the Wall Street Journal points out that the United States reduced CO2 emissions by 1.8 percent from 2005 to 2006. And this was at the same time that the economy grew by 2.9 percent.
Here is their decidedly conservative take on the numbers, along with some interesting stats about Europe compared to the US.
It’s the first time since 1990, when the U.N. began counting these things, that the U.S. has reduced emissions without also suffering a recession.
Critics immediately pointed to the Energy Department’s acknowledgment that the reductions were in part due to higher energy prices and favorable weather. But greater use of lower-carbon energy sources, including natural gas, also played a big role. The U.S. reduction also suggests that letting markets work through higher prices will reduce carbon emissions more than the cap and trade mandates favored by environmental lobbies and most Democrats.
The EU hasn’t yet released figures for 2006. But from 2000 to 2005, the U.S. outperformed Western Europe. Carbon emissions were up 3.8% in the so-called EU-15 during those years, versus 2.5% in the U.S. Over the same period, there has been virtually no difference between the increase in all greenhouse emissions in the U.S. and EU-15.
