Melting ice, falling snow: Sea ice declines enhance snowfall over West Antarctica
As the world continues to warm, Antarctica is losing ice at an increasing pace, but the loss of sea ice may lead to more snowfall over the ice sheets, partially offsetting contributions to sea level rise, according to Penn State scientists......»»
Study shows what kind of salt we use on the roads in winter can make a difference for plants
Increased salinity in soils is a global problem caused, for example, by ions leaching into soils from ice-melting salts used on roads in winter or from seawater seepage in coastal areas......»»
