Global Warming

The researchers have collected thousands of coral samples since 2006.

Corals Reveal El Niño Events Have Become Stronger in Recent Decades, Probably Because Humans Have Been Heating Up the Planet

Researchers used elements trapped within Galápagos corals to understand natural swings in the climate over the past millennium. They hint that variability has gone up over the past 40 years compared to preindustrial times

Streets affected by the catastrophic floods are now covered in mud.

What Triggered the Devastating Floods in Nepal and Tibet, and Are We Due for More in the Future? Here’s What Scientists Know So Far

Natural hazards researchers suspect that a landslide involving a glacier triggered the event, and they say more could happen because of human-caused climate change

Scientists reconstructed the ancient forest canopy using fragments of fossilized leaves.

Forests Didn’t Fare Well During an Ancient Global Warming Event, Offering a ‘Cautionary’ Tale About Today’s Climate Change

An intense global warming event 56 million years ago caused a forest in modern-day Wyoming to lose around 60 percent of its canopy cover, and it took more than 100,000 years to bounce back, a study suggests

This Deadly Shellfish Poisoning Has No Antidote. A Protein Found in American Bullfrogs Could Change That

A study in mice found that a protein called saxiphilin acts like a sponge against a deadly toxin produced by algal blooms. The harmful agent, which accumulates in certain seafood, can cause a life-threatening illness called paralytic shellfish poisoning

The Solomon Siren by Jason deCaires Taylor honors Kale Island, which was submerged a decade ago due to rising sea levels.

“The Solomon Siren” remembers Kale Island, submerged a decade ago in the Solomon Islands

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

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 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

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

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.

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

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

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

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

More than 95 percent of the world’s bergamot oil production is concentrated in Southern Italy’s Calabria region. But harsh conditions driven by climate change threaten that supply.

Earth’s Smells Are Disappearing Because of Climate Change, and It’s a Vast Cultural Loss

A triple threat of pollution, extinction and warming temperatures is altering the way the planet smells. Scientists are only beginning to understand the stakes for humans

Even common backyard birds like house finches are disappearing.

North American Bird Losses Are Accelerating. New Research Suggests Fertilizers and Pesticides May Be to Blame

Scientists found the severest changes in decline rates in places that include hallmarks of high-intensity agriculture

Most Insect Species Call the Tropics Home. But Climate Change Is Pushing Many of the Critters There to Their Heat Limits

Insects in the lowlands will have an especially hard time with rising temperatures, a new study suggests

The annual "catastrophic" molt of the emperor penguin makes the birds especially vulnerable to climate change.

Emperor Penguins’ Annual Molt Might Put Them in Peril. The Sea Ice They Rely on During This Vulnerable Period Is Disappearing

The birds’ already risky molting strategy—in which they shed and regrow all their feathers at once—is becoming even more hazardous due to climate change
