The vast island nation locks away enough fresh water in its ice sheet to raise global sea levels by 20 feet (6 meters), according to the NSIDC. It's Earth's second-largest deposit of land-based ice after Antarctica. And research shows that in recent years its ice has melted faster than ever before. This month, as temperatures in northwestern Greenland approach all-time highs, researchers are encountering unusual, surprising levels of melting ice in the region, according to the AFP.

Mottram and colleagues found that Greenland lost 4.1 billion tons (3.7 billion metric tons) of ice on June 17 alone, and that 41 billion tons (37 billion metric tons) of ice have melted on the island since the start of the month.

The most significant concern here, according to the AFP, is how early this is all happening. Greenland experiences annual ice melt and growth cycles (though usually, unlike in recent years, they've more or less balanced each other out); but in 2019, the melting season began in early...
