SEATTLE, Jan. 4 (UPI) -- A hemisphere-wide weather phenomenon is causing record-breaking amounts of freshwater to accumulate in the arctic's Beaufort Sea, U.S. researchers say.
A decades-long shift in atmospheric pressure associated with a phenomenon called the Arctic Oscillation is causing frigid freshwater flowing into the Arctic Ocean from three of Russia's great rivers to be diverted hundreds of miles to a completely different part of the ocean, a study published in the journal Nature reported.
