Study finds GHG methane offsets its warming ~30% and precipitation increase ~60% by short-wave absorption

Green Car Congress

A new study by researchers from the University of California, Riverside and colleagues in the US and Europe has now found that methane short-wave absorption counteracts ~30% of the surface warming associated with its long-wave radiative effects. However, greenhouse gases also absorb short-wave radiation incoming from the sun.

PNNL modeling study finds climate benefit for cutting soot, methane smaller than previous estimates

Green Car Congress

Cutting the amount of short-lived, climate-warming emissions such as soot and methane won’t limit global warming as much as previous studies have suggested, according to a new study from the Joint Global Change Research Institute in College Park, Md., More realistic emission reductions would likely provide an even smaller climate benefit.

Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The results have important implications for Earth’s climate because methane is about 25 times more powerful than carbon dioxide when it comes to warming the planet over a long period. In addition to coal mining, other major sources of methane emissions globally include wetlands, agriculture, and oil and gas facilities. —Nazar Kholod.
