  3. Science Says: Arctic Is Getting Darker, Absorbing More Heat

    Climate scientists have hypothesized for decades that melting sea ice at the North Pole hastens global warming by decreasing the amount of heat from the sun that’s reflected back into space. According to a new study conducted at the Scripps Institution of Oceanography in San Diego, between 1979 and 2011 the average levels of Arctic albedo—the technical term for the fraction of solar energy ...
