Earth Is Warmer Today Than During 70 to 80 Percent of the Past 11,300 Years
With data from 73 ice and sediment core monitoring sites around the world, scientists have reconstructed Earth's temperature history back to the end of the last Ice Age.
In Greenland and Antarctic Tests, Yeti Helps Conquer Some 'Abominable' Polar Hazards
A century after Western explorers first crossed the dangerous landscapes of the Arctic and Antarctic, researchers funded by the National Science Foundation (NSF) have successfully deployed a self-guided robot that uses ground-penetrating radar to map deadly crevasses hidden in ice-covered terrains.
First Evidence That Magnetism Helps Salmon Find Home
When migrating, sockeye salmon typically swim up to 4,000 miles into the ocean and then, years later, navigate back to the upstream reaches of the rivers in which they were born to spawn their young.
Analysis of Greenland Ice Cores Adds to Historical Record and May Provide Glimpse into Climate's Future
The International North Greenland Eemian Ice Drilling (NEEM) project results indicate that melting of Antarctic ice sheet may have contributed more to sea level rise than melting of the Greeland ice sheet some 100,000 years ago
Magma in Earth's Mantle Forms Deeper Than Once Thought
Study simulating pressures in mantle beneath the ocean floor shows that rocks can melt at depths up to 155 miles.
New ATM Takes Old Phones and Gives Back Green
Using sophisticated artificial intelligence, kiosks evaluate unwanted tech for resale and recycling
Ancient Alteration of Seawater Chemistry Linked With Past Climate Change
Scientists have discovered a potential cause of Earth's "icehouse climate" cooling trend of the past 45 million years. It has everything to do with the chemistry of the world's oceans.
Remote Siberian Lake Holds Clues to Arctic–and Antarctic–Climate Change
Intense warm climate intervals–warmer than scientists thought possible–have occurred in the Arctic over the past 2.8 million years.
Today's Climate More Sensitive to Carbon Dioxide Than in Past 12 Million Years
Geologic record shows evolution in Earth's climate system
