Three extreme weather events that occurred in 2016 would not have been possible in Earth’s pre-industrial climate, according to the sixth annual report on the attribution of extreme weather events issued Dec. 13 by NOAA and the American Meteorological Society (AMS). Show More Summary
A drive around Quebec’s Gaspé Peninsula — bordered by the St. Lawrence River to the north and Chaleur Bay to the south — reveals a rugged coastline dotted with quaint fishing villages, ancient rock formations and an abundance of Devonian-aged fossils that draw amateur and professional geologists alike.
The United States has more than 90,000 dams, with an average age of 50 years. Recent failures highlight the potential for catastrophe and the need for infrastructure maintenance.
Field geologists usually love camping, hiking and all things outdoors. Today, Jess Phoenix is no different, but she wasn’t always that way. As a child growing up in Colorado, she bucked traditional backpack-wearing pursuits. “I would take the horses on trail rides and that was probably the most outdoorsy thing that I did,” Phoenix says.

In a comprehensive global analysis, including data from more than 43,000 rainfall stations and 5,300 river monitoring stations in 160 countries, researchers report that global rainfall is increasing, likely due to warming air temperatures that allow more moisture into the atmosphere, causing more intense rainfall.

With two rovers patrolling the surface of Mars, six spacecraft orbiting above it, and scientists here on Earth studying the Red Planet from afar, new findings are announced often. Here are a few of the latest updates.
There’s never a shortage of geeky pop-culture merchandise and gift ideas available, but sometimes it’s hard to find clever items that are less “Guardians of the Galaxy” and more about the actual galaxy. If you have science lovers onShow More Summary
In 2015, a new dinosaur was discovered in southern Chile, but its odd set of characteristics left paleontologists scratching their heads: Was it a carnivore or an herbivore? A closer look at the bones of the dinosaur, named Chilesaurus, is helping scientists determine how it fit into the Late Jurassic landscape.
On Friday, Dec., 5, 1952, a blanket of thick, yellow smog settled over London, cloaking the city for five days straight. Smog wasn’t uncommon — Londoners called these days “pea-soupers,” based on the yellow-black color — and there were notable smog episodes from the Industrial Revolution (late 1700s) through the 1950s.

Over the last few decades, the Arctic has warmed more than the rest of the planet, but is this Arctic amplification influencing weather patterns in the middle latitudes?
As sea levels creep up around the world, scientists have observed hot spots where regional rates of sea-level rise greatly outpace the global average. But what drives the formation of these hot spots, and how long they last, have been mysteries. Show More Summary
Frogs make up almost 90 percent of amphibians, and with 6,775 described species, frogs are considered one of the most diverse groups of vertebrates on the planet. In a new study in Proceedings of the National Academy of Sciences, researchers...Show More Summary
Most of the world’s lithium is mined in South America and Australia. New research suggests that the United States may have its own untapped lithium supplies in lake deposits in the calderas left behind by large volcanic eruptions. In...Show More Summary
Body mass is a fundamental factor in determining how much food an animal requires, how it moves and grows, and what role it plays in its ecosystem. Measuring modern animals is often a straightforward matter of putting them on a scale,...Show More Summary
Earth is home to more than 1,500 potentially eruptive volcanoes on land, each with a unique character and history. Predicting when and how a particular volcano may erupt is notoriously difficult, in large part because each eruption is unique. Show More Summary
The ancient Romans may have had advanced water distribution systems, but the water pipes they used were highly toxic. Many Roman-era water pipes were lined with lead, leading some archaeologists to suspect a public health crisis among Romans that may have contributed to the empire’s eventual fall. Show More Summary
Since World War II, fiberglass and plastic — which are stronger, lighter and require less maintenance than wood — have become the materials of choice for coastal infrastructure like docks. An unforeseen consequence of this transition,...Show More Summary
Home to more than 30 active volcanoes, Iceland is one of the most vigorous volcanic settings on Earth. A new look at the core-mantle boundary thousands of kilometers below the island is offering one of the most complete pictures yet of how Iceland’s volcanoes are fueled.
In 2011, a large swath of coastal Japan was devastated and more than 15,000 people were killed when the magnitude-9.1 Tohoku earthquake unleashed massive tsunami waves that inundated land with run-up heights of 30 meters in places. In...Show More Summary
On the evening of Monday, Nov. 18, 1929, a magnitude-7.2 earthquake ruptured off the coast of Newfoundland, Canada. Those living on the Burin Peninsula, a foot of land that reaches into the Atlantic Ocean, reportedly felt five minutes of shaking — a confusing sensation, since no one in the area had experienced an earthquake before.
