Today, there’s only one glacier left on Mexico’s tallest mountain. It’s called Jamapa. And scientists say that as much as 60% of it has melted. Until recently, experts estimated that it had maybe just 40 years left. But now, they say it will disappear within the decade.
About a decade ago, several of Greenland’s biggest glaciers suddenly began melting. A decade later, two groups of scientists are trying to unlock the secrets behind a scientific mystery story with potentially big consequences for the future of the island’s rapidly-melting ice sheet.
