For the third consecutive year, the amount of Antarctic sea ice has fallen below two million square kilometers — 772,204.3 square miles. According to data from the National Snow and Ice Data Center (NSIDC), before 2022, the threshold had not been crossed since satellite measurements began in 1979, reported The Guardian. “Sea ice extent in […]
According to a new study by researchers at the Netherlands’ Utrecht University and the University of California, Irvine (UCI), the rate at which Greenland’s surface ice has been melting has increased in recent decades, while surface ice melt in Antarctica has slowed. For the study, the researchers examined the role that katabatic and Foehn winds […]
Recent satellite data from the U.S. National Snow and Ice Data Center shows that Antarctic sea ice extent is far below any level ever recorded. The continent’s sea ice is an important regulator of Earth’s temperature by not only lowering the temperature of the water below, but also reflecting the sun’s rays back into the […]
Rapid global heating due to humans’ use of fossil fuels has contributed to an array of damaging environmental effects on the planet, including extreme weather, unprecedented ocean temperatures and a rapid decline in sea ice. Sea ice is the habitat of several animal species, including polar bears, Arctic fox, caribou and emperor penguins, who live […]
A gigantic iceberg nearly the size of Greater London has broken free from the 492-foot-thick Brunt Ice Shelf in Antarctica. Cracks that had been developing naturally in the ice shelf over the past few years had expanded across the entire shelf, causing the iceberg to finally calve on Sunday, according to a British Antarctic Survey […]
Now, a study published in Geophysical Research Letters in September found that warm water is making its way into a dip beneath East Antarctica’s Denman Glacier, melting 70.8 billion tons of ice each year.
Sea ice forms in the Arctic and Antarctic in winter and retreats in summer, but it doesn’t disappear completely — at least not yet. The floating frozen seawater has a surprisingly strong influence on weather patterns and ocean circulation in the polar regions and beyond. Rapidly shrinking Arctic sea ice has been one of the […]
A massive Antarctic glacier is less stable and could potentially cause more and more rapid sea level rise than previously predicted, a study published Monday in Nature Geoscience finds. The Thwaites Glacier, known as the “doomsday glacier” because it holds enough water to raise global sea levels by multiple feet, is especially susceptible to rising ocean […]
Both the North and South polar regions saw anomalous heat on Friday. Temperatures in parts of Antarctica were more than 70 degrees Fahrenheit warmer than average, while temperatures in parts of the Arctic were more than 50 degrees Fahrenheit warmer than average. This is notable because the Arctic is entering its spring, while Antarctica is […]
