Emissions from fertilizing crops underestimated: Study
2015-07-28 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
MPR: Fertilizing crops in the U.S. Corn Belt emits a potent greenhouse gas, and a new University of Minnesota study shows officials have been underestimating those emissions by as much as 40 percent. The study, published Monday in the Proceedings of the National Academy of Sciences, looked at nitrous oxide, a greenhouse gas about 300 times more potent than carbon dioxide and 12 times more potent than methane. Nitrous oxide gas is emitted from rivers and streams that receive agricultural runoff,...

Tropical peatland carbon losses from oil palm plantations may be underestimated

ScienceDaily: Draining tropical peatlands for oil palm plantations may result in nearly twice as much carbon loss as official estimates, according to a new study by researchers from the University of Minnesota Institute on the Environment and the Union of Concerned Scientists in the journal Environmental Research Letters. Peatlands -- waterlogged, organic soils -- have developed over thousands of years as carbon storage systems. In Southeast Asia, peat swamp forests cover about 250,000 square kilometers, a land...
Major midwest flood risk underestimated by as much as five feet, study finds

ScienceDaily: As floodwaters surge along major rivers in the midwestern United States, a new study from Washington University in St. Louis suggests federal agencies are underestimating historic 100-year flood levels on these rivers by as much as five feet, a miscalculation that has serious implications for future flood risks, flood insurance and business development in an expanding floodplain. "This analysis shows that average high-water marks on these river systems are rising about an inch per year -- that's...
India Heat Wave Death Toll May Be Vastly Underestimated

Agence France-Presse: A heat wave scorching India this week has already killed at least 1,000 people, according to Indian authorities, but that number may be a huge underestimate, one researcher says. It's possible that thousands more have died as a result of the blistering conditions but that their deaths might not have been attributed to the heat wave, said Dr. Gulrez Shah Azhar, a community health researcher and policy analyst at Rand Corp. in Santa Monica, California. Heat waves can be especially harsh on people...
