Misattribution of the energy source — that drives Greenland Ice Sheet melting under very warm weather conditions — means that even sophisticated climate models occasionally underestimate melt rate by 56 percent locally — and 16 percent region-wide — indications of how complex weather and climate dynamics actually are Comments Off on Misattribution of the energy source — that drives Greenland Ice Sheet melting under very warm weather conditions — means that even sophisticated climate models occasionally underestimate melt rate by 56 percent locally — and 16 percent region-wide — indications of how complex weather and climate dynamics actually are
