What impact will future climate change have on food supply? That depends in part on the extent to which variations in crop yield are attributable to variations in climate. A new report from researchers at the University of Minnesota Institute on the Environment has found that climate variability historically accounts for one-third of yield variability for maize, rice, wheat and soybeans worldwide — the equivalent of 36 million metric tons of food each year.
University of Minnesota researchers are part of a national team of scientists that has published a new paper showing for the first time that meltwater from the surface of an ice cap in northeastern Greenland can make its way beneath the ice and become trapped, refilling a subglacial lake. This meltwater provides heat to the bottom of the ice sheet.

A nationally recognized University of Minnesota fisheries professor and colleagues from other universities in the U.S. and Canada have completed an independent review of the Minnesota Department of Natural Resources’ management of Mille Lacs Lake. They confirmed that low survival of young walleye is most likely responsible for the decline in the 132,000-acre lake’s walleye population.

Every day brings new awareness of how bacteria can improve lives — from helping people digest food and fight infections to serving as workhorses in wastewater management, toxic chemical cleanup, and bioenergy production.
Driving vehicles that use electricity from renewable energy instead of gasoline could reduce the resulting deaths due to air pollution by 70 percent. This finding comes from a new life cycle analysis of conventional and alternative vehicles and their air pollution-related public health impacts, published Monday, Dec. 15, 2014, in the Proceedings of the National Academy of Sciences.

Minneapolis (December 4, 2014)—As California finally experiences the arrival of a rain-bearing Pineapple Express weather pattern this week, two climate scientists from the University of Minnesota and Woods Hole Oceanographic Institution have shown that the drought of 2012-2014 has been the worst in 1,200 years.
