Satellite images from NASA show the alarming and above-average ice loss in Greenland due to rising temperatures, with significant melting and a transformation of the snow cover observed during the 2023 melting season.
Fiona, now a post-tropical cyclone, made landfall in Canada Saturday morning. Some two-thirds of Nova Scotia and all of Prince Edward Island are without power.
The powerful remnants of Typhoon Merbok pounded Alaska’s western coast on Sept. 17, 2022, pushing homes off their foundations and tearing apart protective berms as water flooded communities. Storms aren’t unusual here, but Merbok built up over unusually warm water. Its waves reached 50 feet over the Bering Sea, and its storm surge sent water levels into communities at near record highs along with near hurricane-force winds.
Greenland's highest point is experiencing extreme weather conditions, with rainfall recorded for the first time followed by heavy snowfall from the remnants of Hurricane Larry, causing blizzard conditions and strong winds.
Hurricanes form in the tropics, feeding on very warm ocean waters. As they track northward, they may transform to an extratropical storm with an added punch, sometimes reaching southern Greenland, Alaska, and even Arctic latitudes of the North Atlantic.
