WUHAN, Dec. 3 (Xinhua) -- Surface water in North America and Northern Europe indicates global warming may have been underestimated, according to research results published by "Nature Geoscience" magazine on Sunday.
The essay "Increased water storage in North America and Scandinavia from GRACE gravity data", co-written by scientists from China, Canada and Sweden, based their findings on observations of overland water storage through GRACE satellite (Gravity Recovery and Climate Experiment).
According to their research, overland water storage at Canada Prairie and Great Lakes has grown rapidly during the last ten years, which indicated less snow-ice melting water and rainwater flowing into the ocean.
