Eggs and other land foods won’t feed polar bears
Polar bears will not be able to survive on land by eating birds, eggs and vegetation, a new review concludes.
- Climate
Fewer cold snaps in the forecast
Rapid Arctic warming will reduce the frequency of cold snaps throughout much of the Northern Hemisphere, new research suggests.
- Climate
Antarctic ice shelves rapidly melting
Melting around Antarctica is accelerating, with several ice shelves projected to vanish entirely within 100 years.
- Climate
Rain slows whipping hurricane winds
Taking raindrop drag into account — which may slow hurricane winds by as much as 30 percent — could help improve hurricane forecasts.
- Climate
Winter storms 24 times as deadly as estimated
By ignoring car and plane crashes related to bad weather, U.S. tallies of winter storm deadliness severely underestimate hazard.
- Paleontology
Rise of East African Plateau dated by whale fossil
A whale fossil is helping to pinpoint when the East African Plateau started to rise and how the uplift played a role in human evolution, scientists say.
- Climate
Arctic warming bolsters summer heat waves
Sagging storms brought on by rapid Arctic warming worsen summertime heat waves across the Northern Hemisphere.
- Animals
Insects may undermine trees’ ability to store carbon
Insects eat more leaves on trees grown in carbon dioxide-rich environments than those grown without the extra CO2. That may undermine forests as carbon sinks in the future.

Volcanic lightning forges tiny glass balls from airborne ash
The lightning that crackles through volcanic plumes can melt ash into tiny glass beads.
- Plants
Plant growth patterns changing on much of Earth’s surface
More than half of Earth’s land surface has seen major changes in factors such as leaf-on date and how much vegetation grows in a season.
- Climate
Coastal Los Angeles losing fog to urban sprawl
Fog in parts of Southern California has become significantly less frequent due to urban warming.
- Climate
Scientists confirm amassing CO2 heats Earth’s surface
Rising levels of atmospheric carbon dioxide increase the amount of thermal radiation striking Earth’s surface.
