Greenland is losing ice at fastest rate in 350 years

Ice melt across Greenland is accelerating, and the volume of meltwater running into the ocean has reached levels that are probably unprecedented in seven or eight millennia. The findings, drawn from ice cores stretching back almost 350 years, show a sharp spike in melting over the past two decades.
Previous studies have shown record melting on parts of Greenland’s ice, but the latest analysis includes the first estimate of historical runoff across the entire ice sheet. The results, published on 5 December in Nature1, show that the runoff rate over the past two decades was 33% higher than the twentieth-century average, and 50% higher than in the pre-industrial era.
