At the bottom of a glacier in Greenland, climate scientists find troubling signs

Kulusuk, Greenland (CNN) — On one of the hottest days this summer, locals in the tiny village of Kulusuk, Greenland heard what sounded like an explosion. It turned out to be a soccer field's worth of ice breaking off a glacier more than five miles away.
Greenland lost 12.5 billion tons of ice to melting on August 2, the largest single-day loss in recorded history and another stark reminder of the climate crisis.
Kulusuk is also base camp for NASA's OMG (Oceans Melting Greenland) program. OMG scientists traveled to the world's biggest island this year after a heatwave scorched the United States and Europe, smashing temperature records and triggering the mass melting of its ice sheet.
NASA oceanographer Josh Willis and his team are investigating how the ice is being attacked not only by rising air temperatures but also by the warming ocean, which is eating it away from underneath.
A remodeled World War II DC-3 plane, now called Basler BT-57, takes a group of OMG researchers around the coast of Greenland. From the air the crew launch special probes through the ice floor, which then transmit data on temperature and salinity, which is used to plot possible sea level rises and what they would mean for humanity in the future.
