Ice-penetrating radar data from Greenland suggests that shallow water pockets may be common within Europa’s ice shell, increasing the potential habitability of the Jovian moon’s ice shell.

Researchers have detected groundwater beneath a glacier in Greenland for the first time using airborne radar data. If applicable to other glaciers and ice sheets, the technique could allow for more accurate predictions of future sea-level rise.

Researchers have deciphered a trove of data that shows one season of extreme melt can reduce the Greenland Ice Sheet’s capacity to store future meltwater – and increase the likelihood of future melt raising sea levels.

Stanford University scholars discuss the Biden administration’s early actions on environmental issues in the Arctic and how the U.S. government can address threats to ecosystems, people and infrastructure in the fastest-warming place on Earth.
