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.

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

Green Car Congress

The cloud responses, in turn, are related to the profile of atmospheric solar heating and corresponding changes in temperature and relative humidity. —Allen et al. Annual mean near-surface air temperature response to methane, decomposed into (a) longwave and shortwave effects; (b) longwave effects only; and (c) shortwave effects only.

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. Likens, G.E.,

New Molecule Could Lead to New CO2 Capture Methods

Green Car Congress

An unusual bowl-shaped molecule that pulls carbon dioxide out of the air may provide new possibilities for dealing with global warming. Tossell of the University of Maryland notes in the new study that other researchers (Brooks 2006) discovered the molecule—a macrocyclic amidourea—while doing work unrelated to global climate change.

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. —Jiwen Fan.
