As the atmosphere warms, the potential for hail as large as a grapefruit is growing

The Cerne Abbas Giant lies on a hillside.

The Cerne Abbas Giant, a 180-foot-tall geoglyph in southern England, is getting a new layer of chalk

A view of the landslide and tsunami aftermath a few days after the catastrophic events

A Sudden Landslide Triggered Alaska’s 2025 ‘Mega-Tsunami.’ Now, Scientists Have Identified Warning Signs to Predict Similar Events

Natural disasters like the one at Tracy Arm fjord, about 45 miles south of Juneau, could become more common as climate change alters frigid landscapes, according to researchers

Researchers found evidence of degenerative joint disease, trauma and other health problems.

Whalers Didn’t Just Sing Sea Shanties and Seek Adventure. Proof of Laborers’ Grueling Work Is in Their Skeletons, Buried in the Arctic

Remains buried on Svalbard show the brutal toll whaling took on men in the 17th and 18th centuries. Climate change threatens these kinds of archaeological sites across the Arctic

This arrow with a pressure-flaked arrowhead made from gray quartzite dates to the Late Stone Age or Bronze Age and was found on Norway’s ice. The pitch and the animal sinew used to fasten the arrowhead are still preserved, which is exceptionally rare.

Melting Mountain Ice Is Bringing Ancient Secrets to the Surface. Archaeologists Are Racing to Find the Artifacts Before They’re Lost to Time

In Norway’s highest mountains, experts are scouring perilous terrain for pieces of the past, long stored in mint condition in ice patches. As temperatures rise across the world, glacial archaeologists must find the emerging artifacts before they degrade forever

Gentoo penguins have been considered a rare beneficiary of climate change due to their population growth on the Antarctic Peninsula. Splitting the birds into four species brings to light regional threats and declines.

Gentoo Penguins Are Actually Four Different Species, Scientists Say, Revealing They’re Not Quite ‘Winners’ of Climate Change After All

A new study indicates that the adaptable birds evolved into distinct lineages as isolated populations shifted to match their environmental conditions over time. The work has implications for how conservationists assess threats to gentoos

The Bering Strait is a narrow waterway between Russia and Alaska that connects the Pacific and Arctic oceans.

Could Building a Dam Across the Bering Strait Save the Planet From Some Effects of Climate Change?

A preliminary study suggests that blocking off the waterway between Russia and Alaska could help the survival of a key system of ocean currents. But there could be potential unforeseen consequences, particularly to marine ecosystems

Microplastics are particles smaller than five millimeters in length, or narrower than a pencil-tip eraser. 

Microplastics Are Swirling Around in the Atmosphere, Where They Might Be Contributing to Climate Change

Airborne plastic particles, particularly colorful ones, absorb more sunlight than they reflect, which can heat the surrounding air, according to a new study

Two Alpine ibexes butt heads, slamming their horns together in a powerful battle that can be heard from far away. They wandered up the slope together afterward.

See 15 Stunning Images That Won the German Society for Nature Photography’s Annual Contest

From a lunging frog to the majestic movements of penguins, the honored photographs capture the wonder of wildlife and beauty of natural landscapes

The golden artifact, a sword scabbard fitting perhaps belonging to an elite warrior leader 

Cool Finds

A Hiker in Norway Found an Elite Warrior’s Golden Sword Ornament. It Was Likely a Sacrifice to the Gods Made During a Time of Turmoil

Volcanic eruptions, climate change, crop failures, famine and plague all may have swept through Norway in the sixth century C.E., putting pressure on leaders and their communities

Hammarby Sjöstad was originally engineered to have a carbon footprint 50 percent lower than the rest of Stockholm.

This Stockholm Neighborhood Was Built on Ambitious Sustainability Goals. When It Came Up Short, It Doubled Down and Became a Blueprint for Others

The original plan for Hammarby Sjöstad was for an eco-village aimed at attracting the Olympics. They never came, but the locals moved in and, with upgrades, hope to be carbon neutral by 2030

Cattle are a major driver of methane emissions.

Why Do Cows Burp Up So Much Planet-Warming Methane? A Newly Discovered Structure in Their Gut Microbes Could Be a Culprit

The “hydrogenobody” is an organelle inside certain microorganisms that live in a special stomach chamber in cattle, sheep and goats, according to a new study

What if, rather than coral reef rehabilitation remaining a tedious and difficult manual process, conservationists could harness robotics, artificial intelligence and autonomous vehicles to transform it into an industrial-scale endeavor?

Could Underwater Autonomous Robots Save Coral Reefs?

Reef restoration is a slow process, with divers planting coral fragments one at a time by hand. But roboticists are now developing automated planters that could change the game

Sea ice forms off the edge of the Brunt Ice Shelf in Antarctica’s Weddell Sea.

Warm Waters Are Usually Trapped Deep Within the Southern Ocean. Now, They’re Encroaching on Antarctica, Threatening Its Ice

Two new studies that relied on data from a fleet of diving robots show how climate change is altering ocean movements in ways that jeopardize the stability of the polar ice cap

Western monarch butterflies bask in the sun on a eucalyptus branch at Lighthouse Field State Beach. In December 2025, researchers placed ultralight radio tags on some monarchs at this site, hoping to track their movements and identify areas to prioritize for the species’ conservation.

Butterflies Are in Dramatic Decline Across North America. A Close Look at the Western Monarch Shows Why

Pesticides, habitat loss and climate change have taken their toll on the beloved insects. But the experts working with them still find hope for their future

The researchers studied a wetland shaped by Eurasian beavers in Switzerland.

Beavers Are Ecosystem Engineers—and They Might Be Helpful Allies in the Fight Against Human-Caused Climate Change

New research suggests that wetlands created by the industrious rodents are carbon sinks, meaning they store a lot of heat-trapping carbon dioxide—the human-produced gas largely responsible for today’s global warming

Neanderthals survived from roughly 400,000 to 40,000 years ago, when they mysteriously disappeared.

What Killed the Neanderthals? New Research Suggests a Lack of Genetic Diversity May Be Partially to Blame

When the climate cooled, the population of Neanderthals shrank. Most that lived between 60,000 and 40,000 years ago were descended from the same lineage and had very similar DNA

Yasuyuki Aono kept track of bloom dates for Yamazakura cherry trees in Kyoto.

In Japan, a New Steward for 1,200 Years of Cherry Blossom Data Has Been Found, Sustaining a Climate Change Research Project

Climate scientist Yasuyuki Aono, who died last summer, learned to read ancient Japanese script to compile records on peak bloom dating back to the ninth century C.E.

Amud 7 was discovered in a cave in Israel in 1992.

Neanderthal Kids Grew Up So Fast—at Least Compared With Their Human Peers—Thanks to Genetic Adaptations to Their Environment

Scientists think Neanderthal children may have had faster growth rates because larger bodies tend to retain heat more effectively than smaller ones

Students at Anne Wien Elementary School in Fairbanks pilot test the Fresh Eyes on Ice data collection protocol with project team member Allen Bondurant in 2019.

‘Fresh Eyes on Ice’ Teaches Kids to Collect Vital Ice Data in Remote Alaskan Communities

Students measure ice thickness and monitor spring break-up to help save lives in areas where frozen rivers are used as roadways
