Theory about a warming event

Methane is a known agent for capturing the sun's heat-rays and holding that heat in the atmosphere. Recently, a very large methane cloud was discovered in the SW of the US.

This winter has seen a steady significant upward change in the temperatures in the SW of the US, and up into Utah. Could that change be attributable to the methane? Discuss

Following is a link to a DU post which links to and describes the methane bubble,

Four Corners Methane Cloud Size Of Delaware; NASA 1st Thought It Was Instrumental Error
When NASA researchers first saw data indicating a massive cloud of methane floating over the American Southwest, they found it so incredible that they dismissed it as an instrument error. But as they continued analyzing data from the European Space Agency’s Scanning Imaging Absorption Spectrometer for Atmospheric Chartography instrument from 2002 to 2012, the “atmospheric hot spot” kept appearing.

The team at NASA was finally able to take a closer look, and have now concluded that there is in fact a 2,500-square-mile cloud of methane—roughly the size of Delaware—floating over the Four Corners region, where the borders of Arizona, Colorado, New Mexico, and Utah all intersect.

A report published by the NASA researchers in the journal Geophysical Research Letters concludes that “the source is likely from established gas, coal, and coalbed methane mining and processing.” Indeed, the hot spot happens to be above New Mexico's San Juan Basin, the most productive coalbed methane basin in North America.

Methane is 20-times more potent as a greenhouse gas than CO2, and has been the focus of an increasing amount of attention, especially in regards to methane leaks from fracking for oil and natural gas. Pockets of natural gas, which is 95-98% methane, are often found along with oil and simply burned off in a very visible process called “flaring.” But scientists are starting to realize that far more methane is being released by the fracking boom than previously thought.
