This Part Of The US Is Spewing Methane Into The Air At An Alarming Rate

See that small "hot spot" in the U.S. Southwest near the Four Corners region? It shows an extraordinarily dense concentration of the greenhouse gas methane. At triple the standard ground-based estimate, it's the largest concentration ever seen over the United States. So what's causing it? » 10/10/14 7:20am 10/10/14 7:20am
