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

Green Car Congress

The corresponding climate impacts, however, have been only indirectly evaluated and thus remain largely unquantified. Despite our findings, methane remains a potent contributor to global warming, and efforts to reduce methane emissions are vital for keeping global warming well below 2 °C above preindustrial values.

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. In addition to coal mining, other major sources of methane emissions globally include wetlands, agriculture, and oil and gas facilities.

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. Deep convective cloud (DCC) systems in the tropics produce copious precipitation and drive the global-scale circulation. Credit: AAAS, Fan et al.
