Scientists have offered up a convincing explanation for the harsh winters recently experienced in the Northern Hemisphere; increasing temperatures and melting ice in the Arctic regions creating more snowfall in the autumn months at lower latitudes.

Agricultural producers and waterfowl will benefit from a project at South Dakota State University that uses an innovative plant-breeding technique to shave perhaps two years off the time needed to produce winter wheat varieties for farmers in the Prairie Pothole Region of North America.

Winter cover crops are an important component of nutrient cycling, soil cover and organic matter content. Although its benefits are well documented, cover crop use in farming systems is relatively low. Research has shown that time and money are the two primary reasons why farmers are hesitant to adopt the technique. Developing innovative and cost-effective crop cover systems could increase the use of winter cover crops.

Lake Bonney in Antarctica is perennially covered in ice. It is exposed to severe environmental stresses, including minimal nutrients, low temperatures, extreme shade, and, during the winter, 24-hour darkness. But, for the single-celled organisms that live there, the lake is home. To study them, Dr. Rachel Morgan-Kiss from the University of Miami, Ohio, and her team went to Antarctica to sample the ice-covered lake. The article describing her method will be published April 20, in the JoVE (the Journal of Visualized Experiments)

Climate change in the form of reduced snowfall in mountains is causing powerful and cascading shifts in mountainous plant and bird communities through the increased ability of elk to stay at high elevations over winter and consume plants, according to a groundbreaking study in Nature Climate Change.

The 2011 Arctic sea ice extent maximum that marks the beginning of the melt season appears to be tied for the lowest ever measured by satellites, say scientists at the University of Colorado Boulder's National Snow and Ice Data Center.

A NASA-led study has documented an unprecedented depletion of Earth's protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere.

Instinct and the annual increase of daylight hours have long been thought to be the triggers for birds to begin their spring migration. Scientists at the Smithsonian Conservation Biology Institute, however, have found that that may not be the case. Researchers have focused on how warming trends in temperate breeding areas disrupt the sensitive ecology of migratory birds. This new research shows that changes in rainfall on the tropical wintering grounds could be equally disruptive. The team's findings are published in scientific journal Proceedings of the Royal Society B, today, March 30.

Ranchers in the central Great Plains may be using some of their winter downtime in the future to rehearse the upcoming production season, all from the warmth of their homes, according to U.S. Department of Agriculture (USDA) soil scientists.

The punishment your car endures on a cold winter commute pales in comparison to the veritable torture that researchers at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) are inflicting on two electric utility research vehicles - all in the name of science.
