GREENLAND ICE SHEET
7,000 years ago, Greenland’s giant ice dome disappeared as temperatures climbed. Today, scientists say the ancient melting occurred at temperatures close to those now threatening the island’s remaining iceGreenland’s 1,600-foot ice dome vanished 7,000 years ago when temperatures were several degrees warmer than today. Now, scientists have fou...- In 2015, NASA's New Horizons flew past Pluto and captured detailed images of its frozen surface. More than a decade later, scientists revisited the images and found evidence that liquid nitrogen may have once flowed across the dwarf planetScientists found evidence of liquid nitrogen flow beneath Pluto's Sputnik Planitia. This flow may have occurred after rising through cracks...
- In 2019, an international team began monitoring Greenland's Petermann Glacier's floating ice tongue from space. 7 years later, 76.4 sq km broke away, creating a Manhattan-sized ice island, while two more could reduce the tongue by 254 sq kmGreenland's Petermann Glacier lost a large iceberg, its biggest since 2012. Scientists have monitored this glacier's floating ice tongue fo...
