A new study of fossils on an island in the Arctic Ocean show a major episode of extinction that qualifies as a new "great dying."
Tambora brought the world a taste of apocalypse 200 years ago. Today we have better tools to monitor volcanoes like it, but the next eruption of its size will still challenge civilization.
Tsunamis are a worldwide menace with specific local threats. It pays to learn your local situation and keep the knowledge fresh in your community.
Large earthquakes are in our future. When one strikes, there are ways you can help scientists study the event using your phone.
New data from the ancient ice of a tropical glacier shows that lead in gasoline tainted the Earth with the toxic metal far more than any other source, past or present, human or natural.
Geologists are familiar with something most of us have never seen—spherules, or microscopic balls of natural glass that hide in sediments all over the world. A new study reports a previously unknown kind of spherule that’s forged during volcanic eruptions as lightning lashes roiling clouds of hot ash.
A long record of atmospheric observations has put an "official" stamp on the foundation of climate-change science: the greenhouse effect really works the way we've always said it does.
Scientists must play catch-up to industry as we figure out ways to use the deep underground without triggering earthquakes.
Our best climate models, combined with our best climate records, foresee at least a century of profound drought in the Midwest and Southwest.
In the Internet age, many scientists are questioning the traditional publishing model. As we flounder through the digital revolution, it's intriguing to look back at the print revolution of the early Renaissance, which created comparable social and scientific upheaval.
The large asteroid Vesta has added flows of material rich in water to its bag of tricks. It's just one more way this small world acts like a proper planet.
For geologists, even with the advent of modern technology, there are instances when older methods are more effective; picks and shovels are sometimes the best complementary tools available for trenching studies.
A reassessment of historical data suggests that compared to previous estimates, the world's sea level rose more slowly during the 20th centuryand is rising faster now.
A new way of measuring soil erosion in the geologically recent past, before modern civilization, may help put sustainable agriculture on a firmer footing.
