Rapid climatic changes are afoot in the Arctic

Science
Jan. 3 (UPI) -- Rapid climate change is happening in the Arctic, new research confirms, and scientists suggest the changes are quickly altering the geology of the land and ecosystems along the coast.During recent Arctic surveys, a team of researchers at the Woods Hole Oceanographic Institution measured surprisingly high levels of radium-228. The isotope has doubled in concentration over the last decade, which suggests significant changes on land.Scientists believe melting sea ice is creating a larger expanse of open oceans, enabling larger waves, which are stirring up sediments and carrying radium out to sea. The same shifting dynamics could be supplying larger amounts of nutrients to Arctic waters, fueling plankton blooms and altering local food chains in novel ways.Researchers shared the...
