DOI: 10.1029/2023JC020700 The vast Antarctic Ice Sheet holds more than half of Earth’s freshwater. In several places around the continent, the ice extends over the ocean, where […]
Research links intensifying wet and dry swings to the atmosphere’s sponge-like ability to drop and absorb water
[ad_1] Credit: Unsplash/CC0 Public Domain Los Angeles is burning, and accelerating hydroclimate whiplash is the key climate connection. After years of severe drought, dozens of atmospheric rivers deluged California with record-breaking precipitation in the winter of 2022–23, burying mountain towns in snow, flooding valleys with rain and snow melt, and setting off hundreds of landslides. […]
Scientists drill nearly 2 miles down to pull 1.2 million-year-old ice core from Antarctic

DOI: 10.1029/2024JG008298 Dust from open cast mining suffocates surrounding forests and inhibits trees’ ability to capture carbon from the atmosphere more than previously thought, according to new research by scientists in India […]
Rewriting the equation for deformation and flow of watery glacier ice
[ad_1] This polarized light image shows ice grains deformed in experiments with the ring-shear device in Neal Iverson’s Iowa State laboratory. The experiments show that grains, on average, grow about 3 times larger during experiments and develop more irregular boundaries. The different colors indicate different orientations of the grains.

Oil extraction may have triggered small earthquakes in Surrey, study suggests
[ad_1] Credit: Pixabay/CC0 Public Domain A series of more than 100 small earthquakes in Surrey in 2018 and 2019 might have been triggered by oil extraction from a nearby well, suggests a new study by UCL researchers. The earthquakes, which occurred in Newdigate and surrounding areas from April 2018 until early 2019, were recorded as […]
Ocean temperatures hit record highs in 2024, study finds
[ad_1] The ocean surrounding the Antarctic continent is experiencing one of the fastest warming rates. Credit: Chao Ban A study published in Advances in Atmospheric Sciences has found that ocean warming in 2024 has led to new record high temperatures. The ocean is the hottest it has ever been recorded by humans, not only at […]
Cumbre Vieja study suggests that magma composition drives volcanic tremor
