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. Resources Allen, R.J., Randles, C.A.

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. The study is the first to attempt to account for methane escaping from abandoned mines. —Nazar Kholod. Mines are getting deeper every year.

UC Davis Begins $2.8M Studies on Impacts of Escaped Nitrogen

Green Car Congress

University of California, Davis researchers will receive $2.8 million in new grants to study the use and impacts of escaped nitrogen from agricultural production. Nitrogen-based fertilizers help California farmers produce more than 400 agricultural commodities—vegetables, fruits, meats and dairy products—worth $36 billion a year.

Researchers find that abiotic methane can charge deepsea Arctic gas hydrates

Green Car Congress

Researchers from the Centre for Arctic Gas Hydrate, Environment and Climate (CAGE) at the Arctic University of Norway have discovered a growing Arctic abiotic methane- and methane hydrate–charged sediment drift on oceanic crust in the deep Fram Strait of the Arctic Ocean. —co-author and CAGE director Jürgen Mienert.
