WebPolynyas, areas of open water surrounded by ice, form in areas where the wind blows the ice away or where warm water moves up from lower depths and melts the ice cover. "It's really difficult to get the models to form polynyas in the right locations, and the biology is very dependent on that," said Arrigo. When sea water freezes, it discharges ... WebForests and other vegetation in the U.S. consume about a quarter of the carbon dioxide gas the country produces each year. Over the past few decades the size of this “carbon sink” has been growing. NASA researchers now believe increased rain and snowfall are encouraging plant growth, which in turn is sequestering carbon dioxide. fa asztalok és székek

WebClimate change may strengthen vertical wind shear in jet streams, increasing aircraft turbulence. Jet streams are fast-moving belts of wind that travel around the planet in wavy, meandering paths. In this animation depicting a global view of polar and subtropical jet streams, faster winds are colored red; slower winds are colored blue.
