A methane “hot spot” over the Four Corners region of the U.S. Southwest is undergoing serious scrutiny as scientists work to figure out why levels of the gas in the area are so high.
The mysterious methane was firstdetected from space, via a European Space Agency satellite that can measure this potent greenhouse gas. Researchers reported the discovery in October in the journal Geophysical Research Letters, but couldn’t explain where the extra methane was coming from. The “hot spot” persisted from 2003 until at least 2009. And the amount of methane was significant, the researchers reported — equal to nearly 10 percent of all U.S. methane emissions from natural gas.
Now, a team of researchers is tackling the mystery of the extra methane.
