To Prevent Rapid Sea-Level Rise, Reduce Emissions Now Share This The timing of emissions reductions, even more so than the rate of reduction, will be key to avoiding catastrophic thresholds for ice-melt and sea-level rise, according to a new Cornell study
How Climate-Damaging Nitrous Oxide Forms in the Ocean To many people, nitrous oxide, or laughing gas, is only known as a party drug or from the dentist However, the nitrogenous substance also contributes significantly to global warming As a greenhouse gas, its effect in the atmosphere is almost three hundred times more powerful than that of CO2, and it also attacks the ozone layer
Climate Change May Increase the Spread of Neurotoxin in the Oceans Climate-driven oxygen loss in the Black Sea thousands of years ago triggered the expansion of microorganisms capable of producing the potent neurotoxin methylmercury That is shown in a new study published in Nature Water, led by Eric Capo at Umea University, which suggests that similar processes could occur in today’s warming oceans
Melting Ice, More Rain Drive Southern Ocean Cooling - enn. com “We found that the Southern Ocean cooling trend is actually a response to global warming, which accelerates ice sheet melting and local precipitation,” said Earle Wilson, an assistant professor of Earth system science in the Stanford Doerr School of Sustainability and senior author of the March 27 study in Geophysical Research Letters
Soil Bacteria Respire More CO2 After Eating Non-sugar Organic Matter - enn Now, a Northwestern University-led research team has, for the first time, tracked the pathways of a mixture of plant waste as it moves through bacteria’s metabolism to contribute to atmospheric CO2 The researchers discovered that microbes respire three times as much CO2 from lignin carbons (non-sugar aromatic units) compared to cellulose carbons (glucose sugar units), which both add
