How Has Roman Concrete Lasted for Millennia? A 1,900-Year-Old Latrine Offers New Clues About the Material’s Impressive Durability

A chemical process called carbonation, which helps seal cracks, could help explain why many ancient Roman structures are still standing today. Researchers hope that the insights will lead to better modern-day building materials

Earth is currently experiencing an occurrence of the El Niño climate pattern.

Could We Mitigate Super El Niños by Artificially Changing the Climate? A New Study Indicates Yes

Researchers used computer models to see what would have happened had scientists caused marine cloud brightening in the face of strong past El Niños

Scientists analyzed about 25 years' worth of data from the Fram Strait, a passageway where the Arctic and Atlantic oceans meet.

The Arctic Ocean May Have Passed a Crucial Tipping Point That Could Harm Food Webs and Worsen Climate Change

Sea ice loss seems to have triggered a decline in the nutrient nitrate, affecting the tiny organisms that form the foundations of marine food chains and absorb atmospheric carbon dioxide, according to a new study

Tall Trees Were Thought to Be More Vulnerable to Drought. But These Towering Plants in Southeast Asia Have Adapted to Move Water Efficiently

A new study found that enormous dipterocarp trees have special adaptations to transport water up to their highest limbs, challenging the assumption that they would more easily succumb to dry conditions

To turn shrimp shells into a feedstock for hydrogen gas production, the process begins with mashing the shells into a rust-colored shrimp slurry.

How Shrimp Shells Are Being Turned Into ‘Carbon Negative’ Fuel, Food and Construction Materials

Engineers in Singapore have developed a new, multistep chemical process that transforms organic waste into useful, sustainable products

Researchers came up with the new count by studying insect biodiversity in a conservation area in Costa Rica.

Earth Might Be Home to 20 Million Insect Species—More Than Three Times as Many as Previously Thought, a Study Suggests

Recent estimates have come to the consensus that our planet hosts roughly six million species. But new research reveals that those counts may be drastically underestimated

The "cold blob," shown in blue near the top, is also called the Atlantic "warming hole."

As the Ocean Warms, a ‘Cold Blob’ in the Atlantic Has Puzzled Scientists. It Might Be a Warning Sign About a Key Current System

A patch of water south of Greenland and Iceland has cooled by nearly 1.8 degrees Fahrenheit since 1900. A new study suggests that it shows a crucial system of ocean currents is weakening, which could alter Earth’s climate

People cool off in the fountains of the Trocadero gardens, with the Eiffel Tower in the background.

Too Hot for Art? Some Paris Museums and Landmarks Close or Reduce Hours Amid a Record Heat Wave in Europe

Meanwhile, other institutions offer their air-conditioned spaces as a way for residents and tourists to beat the heat

A coral reef in the southern Andaman Sea, in Southeast Asia

Scientists Identify Swaths of Coral Reefs That Might Be Able to Withstand Climate Change, Offering New Avenues for Conservation

New research has mapped more than 64,000 square miles where the crucial habitat seems to be somewhat protected from the impacts of the warming ocean

Located in Sherwood Forest, the Major Oak failed to produce leaves this spring and is now presumed dead.

Major Oak, the 1,200-Year-Old Tree with Ties to the Robin Hood Legend, Is Presumed Dead After Failing to Produce Leaves

The legendary bandit who stole from the rich and gave to the poor is said to have used the massive tree as a hideout while running from the sheriff of Nottingham

Animation showing the surface water temperature changing in the Pacific Ocean from January 1 through June 8.

The ‘Super’ El Niño Has Arrived. Here’s How It Might Affect the World’s Weather and Economy

The naturally occurring climate pattern, characterized by warm surface water in the Pacific Ocean, that has just started could be one of the strongest ever recorded, according to experts

This satellite image from January 16, 2022, reveals formaldehyde in blue. The volcanic plume from the Hunga Tonga-Hunga Ha’apai volcano traveled over the South Pacific.

Tonga’s Enormous Volcanic Eruption Cleaned Up Part of Its Own Methane Emissions in 2022, Hinting at a Way to Fight Climate Change

Researchers analyzed satellite imagery of the volcanic plume and found evidence that the potent greenhouse gas had broken down. The work could inform artificial interventions aiming to mitigate global warming, scientists say

A large hailstone made up of an aggregate of smaller ice particles

Giant, Destructive Hail Is Becoming More Common With Climate Change, Study Says

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

The Cerne Abbas Giant lies on a hillside.

England’s Most Famous Naked Giant Will Glow White Again, Thanks to Help From Hundreds of People Performing a Ritual of Restoration

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.
