Discrepancies between observations and climate models of large-scale wind-driven Greenland melt influence sea-level rise projections
peer reviewed While climate models project that Greenland ice sheet (GrIS) melt will continue to accelerate with climate change, models exhibit limitations in capturing observed connections between GrIS melt and changes in high-latitude atmospheric circulation. Here we impose observed Arctic winds i...
