Global Warming

Photographs of the Rhône glacier and the attempts to save it

Art Meets Science

Art Exhibition Immortalizes Switzerland’s Rhône Glacier, Predicted to Disappear by 2050

Ohan Breiding’s “Belly of a Glacier” combines experimental film and photography to reflect on a moment of loss—and to fight against it

A NASA image of Florida in 1992. Coastal communities are most the vulnerable to the effects of sea level rise.

Sea Levels Rose More Than Expected in 2024, According to a NASA Analysis

Ocean warming and thus thermal expansion played a major role in last year’s increase

Greenhouse gas emissions will decrease the amount of satellites that can safely orbit Earth, according to a new study.

Climate Change Might Increase Satellite Collisions, Limiting How Many Can Safely Orbit Earth, Study Finds

Greenhouse gas emissions could reduce drag in the upper atmosphere, leaving more space debris in orbit and making satellites more vulnerable to damage, according to new research

Researchers studied the impact of extreme heat on older adults' "epigenetic clocks," which measure aging-related changes to DNA.

Extreme Heat Could Make Older Adults Age Faster by Altering Their DNA, Study Finds

Researchers compared genetic markers of aging to daily temperature records in areas across the United States and found that elderly people exposed to more hot days showed more rapid biological aging

The Palos Verdes Peninsula in Los Angeles experiences slow-moving landslides that accelerated last fall, according to recent research.

Parts of California Are Sinking, and It Could Worsen the Effects of Sea-Level Rise, NASA Study Finds

The ground in many parts of the state—including Los Angeles, San Francisco and the Central Valley—is subsiding due to groundwater withdrawal, landslides and compacting of sediment

An illustration of the Antarctic Circumpolar Current, with branches connecting to other ocean currents

Earth’s Strongest Ocean Current Could Slow 20 Percent by 2050 Because of Climate Change, Study Finds

The Antarctic Circumpolar Current is involved in everything from storing carbon to guarding Antarctica from invasive marine species, and a slower current could have far-reaching consequences

A crocodile wears a satellite tracker in Queensland, Australia. Scientists monitored the reptiles for 15 years and recorded their body temperatures.

Crocodiles in Australia Are Shifting Their Behavior Because of Climate Change, and It Might Harm Their Ability to Hunt

A new study finds that as temperatures rise, the animals are getting hotter, spending less time diving and putting more effort into cooling off

President Donald Trump holds up an executive order. He signed dozens of executive orders on his first day in office, undoing many of his predecessor’s policies.

President Trump Orders the U.S. to Exit the World Health Organization and Paris Climate Agreement on His First Day in Office

The actions will take effect in a year, reinstating withdrawals he had set in motion during his first term

The Mauna Loa Observatory in Hawaii recorded the highest annual jump in atmospheric carbon dioxide levels since its records began in 1958.

Hawaiian Observatory Clocks Highest Annual Jump in Atmospheric Carbon Dioxide Since Its Records Began 67 Years Ago

The change measured by the Mauna Loa Observatory was likely driven by wildfires and continued burning of fossil fuels, scientists say

A view of the Palisades fire on January 9. The strong Santa Ana winds that fueled much of the L.A. wildfires’ destruction are expected to relax for a few days.

L.A. Fire-Fueling Winds Slow Down, Offering a Short Reprieve. What Are the Santa Ana Winds, and Why Do They Fan the Flames?

The seasonal gusts have exacerbated the deadly fires, and they’re expected to pick back up next week

The two Just Stop Oil activists spray-painted "1.5 is dead" on the gravestone of Charles Darwin.

Climate Activists Spray-Paint Warning on Charles Darwin’s Grave

The two protesters hoped to draw attention to reports that global temperatures in 2024 exceeded 1.5 degrees Celsius above pre-industrial levels for the first time

Researchers found that in 2023, a decrease in low-altitude clouds, specifically over the Atlantic Ocean, drove an increase in the planet's temperature.

Scientists Find Another Reason Why 2023 Was So Hot: a Decline in Low-Lying Clouds

According to new research, Earth might have reflected less solar radiation last year than in any other year since 1940, a trend that adds to the planet’s warming

The sun sets over Death Valley, California, on July 7, 2024, a day when its temperature reached 129 degrees Fahrenheit.

Climate Scientists Project 2024 Will Be the Hottest Year on Record—and the First to Pass 1.5 Degrees Celsius of Warming

After November 2024 was the second warmest November in the books, experts say the year is “effectively certain” to break the heat record set by 2023

New England Aquarium staff treat a cold-stunned sea turtle.

Hundreds of Sea Turtles With Hypothermia Are Washing Up in Cape Cod, Cold-Stunned as Temperatures Drop

New England Aquarium staff and volunteers are treating the reptiles, which have gotten trapped after venturing north earlier in the year. Experts say climate change is leading more turtles to get stranded in the bay

Grazing cows produce more methane than feedlot cows because of the fiber content of the grass they consume.

Eating Seaweed Could Make Cows Less Gassy, Slashing Methane Emissions From Grazing by Nearly 40 Percent

A new study finds that feeding seaweed pellets to grazing beef cattle dramatically reduces their greenhouse gas emissions

A NASA scientist's picture out the window of a plane over Greenland, combined with the new radar map of Camp Century, at the bottom.

NASA Radar Detects Abandoned Site of Secret Cold War Project in Greenland—a ‘City Under the Ice’

Camp Century was built in 1959 and advertised as a U.S. research site—but it also hosted a clandestine missile facility

The yellow powder is a type of compound known as a “covalent organic framework,” or COF.

This New, Yellow Powder Quickly Pulls Carbon Dioxide From the Air, and Researchers Say ‘There’s Nothing Like It’

Scientists say just 200 grams of the material could capture 44 pounds of the greenhouse gas per year—the same as a large tree

A view of a snow-covered Mount Fuji from Fujiyoshida in Japan.

Japan’s Mount Fuji Has Now Remained Snowless for the Longest Time in Its 130-Year Record

After a summer that tied for the country’s hottest, meteorologists say an unusually warm autumn is delaying snowfall

Polar bears are spending more time on land as sea ice shrinks.

Polar Bears Are Exposed to More Parasites, Viruses and Bacteria as the Arctic Heats Up

Pathogens are more common in polar bears living in the Chukchi Sea now than they were three decades ago, a new study suggests—but it’s not yet clear what that means for the mammals’ health

Could a private citizen get hold of a genome and use it to bring an extinct animal back to life? 

Could Anyone Bring an Extinct Animal Back to Life? And More Questions From Our Readers

You’ve got questions. We’ve got experts
