Satellite data, studied by scientists at NASA and the University of Michigan, has revealed that one small “hot spot” is responsible for producing the largest concentration of greenhouse gas methane seen over the United States – more than triple the standard ground-based estimate. The hot spot, near the Four Corners intersection of Arizona, Colorado, New Mexico and Utah, covers about 2,500 square miles (6,500 square kilometers). It is about half the size of Connecticut.
