Climate Change Is Turning Lakes Brown
As global temperatures increase, blue lakes in North America and Europe are projected to become green-brown. According to recent research that provides the first global…
Predicting Earthquakes: Slight Shifts in Magnetic Field Preceded California Quakes
Magnetometers detected faint signals that may improve our understanding of what happens before earthquakes and offer promise for early detection. Scientists studying intermediate to large…
New Clues to Earth’s Formation From Ancient Helium Leaking From the Planet’s Core
Vast stores of helium from the Big Bang lingering in the core suggest Earth formed inside a solar nebula. Helium-3, a rare isotope of helium…
Hidden Magnitude-8.2 Earthquake Source of Mysterious Global Tsunami
Researchers uncover why a complex earthquake in the south Atlantic sent an unexpected tsunami around the world in 2021. A 47 km-deep, magnitude 7.5 earthquake…
New ICESat-2 Observations Show We’re Losing Arctic Sea Ice at a “Frightening” Rate
End-of-season Arctic multiyear sea ice is about 1.5 feet thinner in 2021 than in 2019 Arctic Ocean sea ice lost one-third of its volume in…
“Blue Blob” Near Iceland Could Slow Glacial Melting Until 2050
Chilly seawater may slow ice loss on the island until 2050, then warming and melting may accelerate. A region of cooling water in the North…
Early Disaster Warning: Tsunamis’ Magnetic Fields Are Detectable Before Sea Level Change
Magnetic field information could provide earlier disaster warning to at-risk regions, potentially saving lives. A new study finds the magnetic field generated by a tsunami…
How Long Do Black Carbon Particles Linger in the Atmosphere?
Researchers uncover how black carbon evolves from hydrophobic particles to cloud nucleation sites, eventually removing the heat-absorbing particles from the sky. There’s a stubborn, heat-absorbing…
High-Speed Impacts May Have Shaped Venus’ History – And Explain Why It Is Uninhabitable
New modeling suggests fast collisions could explain why Earth is habitable while Venus is not. New modeling suggests large, high-speed impacts during Venus’ early history…
Carbon Dioxide Cold Traps on the Moon Confirmed – Major Impact on Future Lunar Missions
The traps likely contain solid carbon dioxide that could be used to sustain robot or human presence on the Moon. After decades of uncertainty, researchers…
Icequakes Likely Rumble Along Geyser-Spitting Fractures on Saturn’s Icy Moon Enceladus
Seismic activity could give scientists a read on the thickness of the ice encasing the moon and the oceans believed to lie beneath. Tidal stresses…
1,000 Years of Glacial Ice Reveals Unexpected Evidence of “Prosperity and Peril” in Europe
Evidence preserved in glaciers provides continuous climate and vegetation records during major historical events. Europe’s past prosperity and failure, driven by climate changes, has been…
Ancient Driftwood Tracks 500 Years of Arctic Warming, Currents, and Sea Ice
Fallen trees kept afloat in sea ice reflect accelerated ice loss in the last 30 years. A new study reconstructs the path of frozen trees…
Earth Is Dimming – It’s Due to Climate Change
Warming oceans cause fewer bright clouds to reflect sunlight into space, admitting even more energy into earth’s climate system. Warming ocean waters have caused a…
New Estimate Makes Groundwater – Not Ice Sheets – Earth’s Largest Water Reservoir on Land
New research doubles volume of salty water two to 10 kilometers beneath the surface that could store waste fluids, sequester carbon, and direct our search…
Could Low-Altitude Magnetic Reconnection Power Jupiter’s Polar Aurorae?
Magnetic reconnection events less than 2 Jovian radii above the planet’s cloud tops could explain why Juno has yet to observe a source for Jupiter’s…
The Changing Climate’s Snowball Effect – Can New Technologies Help?
Shrinking snowpack, thawing permafrost, and shifting precipitation patterns have widespread consequences. Can new technologies—and public policies—help communities adapt? It begins at the height of winter…
