20250322_shc_z03_882 March 22, 2025 - Arctic - Winter sea ice cover in the Arctic was the lowest it's ever been at its annual peak on March 22, 2025, according to NASA and the National Snow and Ice Data Center (NSIDC). At 14.33 million square kilometers (5.53 million square miles), the maximum extent fell below the prior low of 14.41 million square kilometers (5.56 million square miles) in 2017. The map above shows the ice extent on March 22, the day of the 2025 maximum. To determine extent, scientists project satellite observations of sea ice onto a grid and then add up the total area of each cell that is at least 15 percent ice-covered. The yellow outline shows the median sea ice extent for March (1981-2010), the month when the ice generally reaches its maximum extent. A median is the middle value; that is, half of the extents were larger than the yellow line and half were smaller. (Credit Image: © NASA Earth/ZUMA Press Wire)

20250119_fap_s51_029 January 19, 2025, Kangerlussuaq, Greenland: Greenland: Airmen from the USAF at Camp Raven on the Greenland icecap, undergoing arctic survival training..Some three miles in the distance is the now-disused DYE-2 radar station. The station was part of achain of early-warming radar stations that became redundant with the advent of surveillance satellites. An autonomous territory which remains part of the Denmark, Greenland, situated in the North Atlantic between Canada and Iceland, has a huge landmass of 2.1+million square kilometers of which 81% is covered by a glacier some 2,300meters thick. Larger than Germany, the thin strip of habitable land hugging its circumfrence supports a popultion of only 56,421 (Credit Image: © Rob Schoenbaum/ZUMA Press Wire)

20250119_fap_s51_014 January 19, 2025, Kangerlussuaq, Greenland: Greenland: A New York Air National Guard ski-equipped C-130 aircraft that transported a contingent of USAF aircrew the Greenland icecap for arctic survivial training. The aircraft is operated by the 109th Airlift Wing which specializes in polar missions. Several miles in the background is the enormous DYE-2 cold-war era radar station. It became operational in 1958 as part of a chain of early warning radar stations operated by NORAD, It was shut down in the 1980s when surveillance satellites made it obsolete..

20240615_shm_z03_895 June 15, 2024 - Greenland - DETAIL: The layer of sea ice that caps the Arctic Ocean hits its maximum thickness during the long, dark polar night that accompanies winter. When sunlight and warmer temperatures return in spring, the ice pack thins and breaks up as currents and winds funnel ice floes south through narrow outlets on the eastern and western edges of Greenland. For decades, experts have tracked the state of the ice from spring to fall as the melt season unfolds, using satellite data to measure sea ice extent and concentration. They did so as usual in 2024, but a team of NASA-sponsored researchers also had a rare opportunity that year to travel to northern Greenland to study little-understood aspects of the melt season up close (Credit Image: © NASA Earth/ZUMA Press Wire)

alb3887208 This is how North America may appear with average sea level about 100 meters (330 feet) above today's. Such a dramatic rise in sea level could occur if all of the Earth's glaciers were to melt.. In this image the Gulf of Mexico and Atlantic Ocean have inundated nearly all of southeastern United States including the entire state of Florida, nearly all of Louisiana, and significant portions of the other southeastern states and the District of Columbia. Major U.S. cities submerged include New York City, Boston and Houston, and on the west coast Los Angeles, San Francisco, and much of San Diego.. To the north the Hudson Bay has grown to claim much of the Canadian provinces of Ontario, Quebec, Manitoba and Nunavut. Further north Greenland's entire ice sheet, 110,000 years old and holding about 700,000 cubic miles of fresh water, has completely melted.. A likely cause of a catastrophic melting of the Earth ice stores would be a change in climate, a sudden rise in the global temperature accelerated by a runaway greenhouse effect. While the amount of water held by the Earth's glaciers can be calculated with some accuracy, the exact mechanism that would set those glaciers to melting, and how long it would take for them to melt, is poorly understood. Some models suggest that several millennia of higher temperatures would be required to melt all the world's glaciers, while others predict much faster processes on the scale of centuries, or even decades.

913_03_PO00332 Iceland, True Colour Satellite Image. Iceland, satellite image. This is a European country surrounded by the northern Atlantic Ocean. It lies just south of the Arctic Circle. Its capital, Reykjavik (in the bay at centre left), is the northernmost in the world. Iceland has a population of around 300,000 (2006). It is situation on a plate boundary and is thus very geologically active. This allows it to derive a large amount of its energy from geothermal sources, which it supplements with hydroelectric power. Together they provide around 99% of the country's energy. Composite image using data from LANDSAT 5 & 7 satellites.
