America’s rivers are changing colors, moving from blue to shades of green and yellow, a group of researchers says.
A team of scientists pored over hundreds of thousands of river images dating back to 1984 and published their findings in the journal Geophysical Research Letters in December. They found about a third of American rivers have changed color, according to lead author John Gardner of the University of North Carolina at Chapel Hill.
