By modeling over 4 billion years of the Moon’s impact history, scientists estimate that the lunar poles may harbor billions of metric tons of subsurface ice.
An exceptionally strong stratospheric polar vortex coincided with a record-breaking Arctic Oscillation pattern and ozone destruction during the 2019–2020 winter season.
A new study showing the most vulnerable protected areas—the poles and the subtropics—could help prioritize their care.
Saturn’s moon Enceladus boasts fierce tiger stripes around its south pole, a mystery that has long puzzled scientists. New research explores the stripes by examining how the moon’s ice breaks.
Using topographic data, researchers have estimated the ages of water ice–containing craters near the Moon’s poles and ruled out volcanism as being a primary route for water delivery.
Basin-wide ocean gyres have been observed to be slowly migrating toward the poles and, although natural variations contribute, climate simulations suggest the shift is in response to global warming.
A new community pool of seismic instrumentation will facilitate and advance geologic and cryospheric research in Earth’s ice-covered environments.
New modeling indicates that global subsurface ocean currents distribute submerged microplastics along very different routes than those traveled by floating plastic debris.
Getting the polar stratosphere right is critical in the simulation of North Atlantic climate change, which is shaped by the interaction of Arctic Amplification and tropical upper tropospheric warming.
A new study ties layers in the polar deposits of Mars to changes in climate driven by orbital variations, constraining accumulation rates and further deciphering the climate history of the Red Planet.
