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. This in turn reduces the amount of water that evaporates.

UMD-led study: road salts and other human sources are threatening world’s freshwater supplies

Green Car Congress

But a new study led by Sujay Kaushal of the University of Maryland warns that introducing salt into the environment—whether it's for de-icing roads, fertilizing farmland or other purposes—releases toxic chemical cocktails that create a serious and growing global threat to our freshwater supply and human health.

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. Kholod said that when a closed mine is flooded, water stops methane from leaking almost completely within about seven years. —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. Credit: AAAS, Fan et al.

Satellite study shows drought-stricken Colorado River Basin states depleting their groundwater

Green Car Congress

A new satellite study finds more than 75% of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought. This is a lot of water to lose. Credit: U.S.
