Seven Down in Greenland: An Air Rescue Disaster

A forced landing on Greenland’s ice cap set in motion one of the most extensive—and costly—search-and-rescue operations ever mounted. It was called the Snowball Route—officially the North Atlantic Ferry Route—from Goose Bay, Labrador, to the one-way runway at Bluie West One on Greenland; then across to Keflavik, Iceland, to refuel again; on to Prestwick, Scotland; and finally toGet price

Greenland Ice Sheet surface mass balance under stratospheric

Changes in surface temperature have dramatically affected the mass budget of the Greenland ice sheet over the last few decades, but changes in precipitation and radiation budget have also been as important in controlling the extent of the ice sheet. Geoengineering by stratospheric sulfate aerosol injection could slow ice melting by reducing summer temperature and insolation, however suchGet price
