Climate Change

1. Modern Warming Is Undoing Millennia of Arctic Ice Cover

Plants and rocks at the edges of glaciers have been entombed in ice for more than 40,000 years. Modern warming, unmatched in 115,000 years, is now uncovering these landscapes.

2. The Deep Blue Sea Is Getting Bluer

Ocean color will intensify in the next century due to global warming altering phytoplankton communities.

3. House Hearing Stresses Climate Change’s Links to Ocean Health

Backed by new Democratic congressional leadership determined to focus on science, experts call for swift action to avoid or limit irreparable environmental harm.

4. Glacial Census Reveals Ice Thicknesses Around the World

Researchers modeled over 200,000 glaciers and found that mountainous regions in Asia contain significantly less glacial ice than previously estimated.

Hazards & Disasters

1. Ancient Tsunami Tied to Volcanic Flank Collapse in Italy

Stromboli’s volcanic cone may have suffered multiple flank collapses between the 14th and 16th centuries, triggering tsunamis that led to the abandonment of the island.

2. Forensic Probe of Bali’s Great Volcano

Evidence from volcanic crystals sheds light on magma storage under Mount Agung and helps explain this giant volcano’s frequent eruptions.

2. Study Suggests Prospect of Recent Underground Volcanism on Mars

Researchers argue there needs to be an underground source of heat for liquid water to exist underneath the planet’s south polar ice cap, as predicted by a previous study.

Global Change

1. An Inherently Noisy Ocean Can Disguise Regional Sea Level Trends

Sea level trends in different regions of the ocean caused by both natural and man-made changes in the atmosphere can be partially hidden by internal random processes intrinsic to the ocean.
