Beneath the ice
To predict how much climate change will raise sea level, researchers are studying ice shelves, where vast expanses of ice meet the ocean.
A sharper view of the world’s oceans
Models of the behaviour of the oceans with higher spatial resolution could lead to more accurate climate predictions.
Nature Outlook: Physical oceanography
The oceans are an integral part of our planet’s climate system. Understanding the physical processes at work in the sea is crucial therefore to making accurate predictions about the effects of climate change...
Frozen Researchers Will Greatly Improve Arctic Weather Prediction
Their data will also bolster climate models that forecast extreme weather where we all live
As Seas Rise, King Tides Increasingly Inundate the Atlantic Coast
Cities from Key West to Boston have seen notably worse nuisance flooding this fall
Global Warming Is Not Part of Natural Climate Variability
A common argument among skeptics is put to rest
Warming Will Cost Rich and Poor Countries Alike
Limiting global temperature rise will substantially reduce the economic toll of climate change
Dinosaur-Killing Meteorite Caused Acidification That Led to Mass Extinction
The lowering of ocean pH linked to the Chicxulub impact is similar to what could happen if modern carbon dioxide emissions continue
Extreme Snows in Greenland Caused Ecosystem’s “Reproductive Collapse”
Delayed plant flowering and nesting meant some Arctic animals’ offspring likely did not survive the winter
Ship Freezes Itself in Arctic Ice to Study Climate Change
Researchers trapped in the central Arctic Ocean for a year prepare to unlock secrets of the region’s changing climate
Ice Sheets Are Eroded by “Upside-down Rivers”
Warm ocean waters cut deep channels in the ice that exacerbate melting and sea level rise
How Did Water Get on Earth?
About 70 percent of our planet’s surface is covered with water, and it plays an important role in our daily lives. But how did water get on Earth in the first place?
Wildlife Trade Entangles Nearly a Fifth of the Planet’s Vertebrate Animals
In the first global estimate of its kind, researchers tally an incredible 5,600 species harvested for commercial use—and predict which ones could be next
Corals Can Inherit Symbiotic Adaptations to Warming
Adult corals can reshuffle their symbiotic algae species to adapt to warming waters—and, it appears they can pass those adaptations on. Christopher Intagliata reports.
Science News Briefs from around the World
A few brief reports about international science and technology from Hungary to Japan, including one about a wine grape in France that DNA testing shows has been cultivated for almost a millennium...
Kicking Climate Change: Wins for Health, the Economy and Security
Former EPA administrator Gina McCarthy talks with Scientific American’s Andrea Thompson about the widespread benefits of taking action against climate change.
Ancient, Pancake-Shaped Marine Animals Were on the Move
The large, disk-shaped Dickinsonia roamed in search of food 550 million years ago
The World’s Oceans Are Losing Power to Stall Climate Change
A new U.N. report predicts more powerful storms, increased risk of flooding and dwindling fisheries if greenhouse-gas output doesn’t fall
