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 the United States in 2015, about one-third of abandoned mines were flooded. —Nazar Kholod.

PNNL-led international study finds ultrafine aerosols have outsize impact on storm clouds, precipitation

Green Car Congress

Scientists have known that aerosols may play an important role in shaping weather and climate; the new study shows that the smallest of particles have an outsize effect. Aerosol impacts are a key uncertainty in understanding the current and future climate as well as extreme weather. —Jiwen Fan.
