Nicolas ‘Niko’ Dubreuil, a veteran polar explorer with over three decades of experience in the Arctic, knows first-hand the dangers of navigating the region’s icy landscapes. In 2001, while trekking on an icepack in Greenland, he suffered a severe fall, sustaining major injuries. Instead of being deterred though, the experience left him captivated
Mathieu Ardyna, Université Laval and Juliette Provencher, Université Laval Earlier this year our international team of scientists from the Refuge Arctic consortium departed Iqaluit, Nvt. on a 56-day research expedition in the far north. We were sailing aboard the icebreaker CCGS Amundsen and our main objective was to study the high latitudes of
Antarctic ice drives crucial deep-ocean currents that help regulate Earth’s climate. But the system is slowing down. Part of Earth’s deep-ocean conveyor belt is slowing, and melting ice is to blame, according to new research. When the sea freezes around Antarctica’s fringes in winter, the ice expels salt into the water below. Trillions
A pair of studies demonstrate the uncertainty over when the Arctic will become seasonally sea ice free. Every September since 1979, the U.S. government has measured the extent of sea ice in the Arctic. And the picture is not a pretty one—more than 2 million square kilometers have been lost in that time,

The world has now warmed by 1.2℃ above
An international initiative aims to collect a comprehensive airborne data set from the Antarctic Ice Sheet margin to better estimate ice discharge and sea level contributions today and in the future. Most of Earth’s land surfaces have been mapped in great detail—the courses of rivers, outlines of ocean shores, mountain heights, and valley
Earth’s ice sheets have misplaced 28 trillion tons of ice mass because the Nineteen Nineties and will proceed accelerating as hotter oceans undercut glaciers alongside coasts, The Washington Put up stories. A brand new research printed within the journal Copernicus says that between 1994 and 2017, the Arctic misplaced 7.6 trillion tons of
