An international study has found that Earth’s glaciers will lose 76% of their 2020 mass under current climate policy pledges made by nations. Those pledges would lead to a global mean temperature 4.9 degrees Fahrenheit above preindustrial levels. Consequences of the glacier mass loss include a 9-inch sea level rise, changes in biodiversity and increased […]
A powerhouse of ice flows rapidly on Greenland’s west coast, heading toward the ocean. Some of Earth’s largest icebergs are produced here, tumbling from the tip of Jakobshavn Glacier. Jakobshavn is one of Earth’s fastest-moving glaciers and one of the Greenland Ice Sheet’s largest glaciers. It produces about 10% of Greenland’s icebergs. “We don’t have a good […]
Astronomers confirm the existence of small, hot and likely rocky planets by observing the subtle gravitational wobbles of the star they orbit Researchers supported by the U.S. National Science Foundation have discovered four tiny exoplanets orbiting Barnard’s star, a red dwarf at the center of the nearest single-star system to Earth. Using a specialized […]
New research examining 11,700 years of bowhead whale persistence throughout the Arctic projects that sea ice loss due to climate change will cause their habitat to severely contract by up to 75 per cent. An international team led by researchers from the University of Adelaide and the University of Copenhagen reconstructed an 11,700-year ecological baseline […]
