These visualizations show how the Antarctic ozone hole grew from August 1, 2026 to September 12, 2026. 

September’s Ozone Hole Was the Biggest It Has Been in 25 Years

The size of the hole in the stratosphere’s ozone layer fluctuates every year, but last month’s, measuring 10.6 million square miles, was especially large

Could 2026 Be a Year With No Atlantic Hurricanes? We’ve Surprisingly Passed Their Peak Month Without Any, Thanks to El Niño

Atlantic hurricane season runs from June through November, and the last time one passed by without an intense cyclone was more than 100 years ago. While the ongoing “super” El Niño seems to be suppressing storms in the Atlantic, the Pacific Ocean is being overactive

Parts of New Jersey experienced severe flooding over the weekend during the nor'easter.

A Shark Was Spotted Swimming Through the Flooded Streets of New Jersey During the Nor’easter

The creature has been identified as a smooth dogfish, a harmless species found throughout the western Atlantic Ocean. It wasn’t the only animal caught in the chaos brought by the storm system

The wreckage could belong to the “Warren Sawyer,” a three-masted cargo schooner that foundered more than 140 years ago

The "super" El Niño event in the Pacific Ocean has been brewing since June and will extend through February.

Scientists Say Scorching Temperatures Brought on by the ‘Super’ El Niño Could Kill Nearly Half a Million People by February

The predicted number, which includes deaths since June, likely represents an underestimate of total deaths. The heat could linger beyond February, and the climate swing could bring about other life-threatening conditions, including flooding, wildfire and infectious diseases

Smoke from massive wildfires in Canada engulfed the New York City skyline, reducing visibility and casting an orange haze over city on July 16, 2026.

From 22,000 Miles Up, This Satellite Tracks Airborne Health Threats Almost in Real Time

The new instrument, called TEMPO, captures hourly snapshots of the pollutants swirling in the daytime atmosphere over North America—“chemical weather” reports that are helpful to public health researchers and government officials

Western Europe experienced back-to-back heatwaves this summer.

Did You Suffer a Sweltering August? You Weren’t Alone. It Tied for the Month With the Hottest Global Temperatures on Record

Last month, the air temperature averaged 62.53 degrees Fahrenheit, tying with July 2023 as the toastiest month ever documented by the European Union’s climate service

Observations by amateur astronomers and imagery from the Hubble Space Telescope have revealed a ten-sided shape around Saturn’s south pole.

A Mysterious Decagon Unexpectedly Appeared Around Saturn’s South Pole. The Ten-Sided Shape Seems to Be a Wave in the Atmosphere

Decades ago, scientists found a hexagon around Saturn’s north pole. Now, recent images reveal a decagon in the planet’s southern hemisphere—and it seems to have recently formed

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

‘Hunger Stones’ Resurface in Europe, Bringing Centuries-Old Warnings Back Into View as Rivers Hit Historic Lows

As drought exposes stretches of riverbed in central Europe, markers carved by past generations to record low water levels are emerging once again

Claude Monet lived in Giverny, a small village about 50 miles northwest of Paris, for more than four decades.

In France, Brutal Summer Heat Waves Are Taking a Toll on the Flowers That Inspired Claude Monet’s Most Beloved Paintings

The colorful nasturtiums at the artist’s house and gardens have been hit particularly hard this summer as France grapples with a record 52 heatwave days

A series of floods devastated medieval Europe.

Centuries Ago, Europeans Were Plagued by Constant Flooding, With 16 Major Events That Killed Thousands Over the Course of Just Three Years

When researchers went looking for information about the legendary Magdalena Flood, they were surprised to discover that it was just one of many extreme weather events that ravaged the region in the early 1340s

When an American Airplane Crashed Into a School in 1944, an English Village Lost Almost All of Its Youngest Children. Why Has WWII’s Worst Civilian Aviation Accident Been Forgotten?

On August 23, 1944, a test flight over the village of Freckleton, located in northwest England, ended in disaster, claiming the lives of 61 people, including 38 students between the ages of 4 and 6

The crew of the Artemis 2 mission captured this image of a total solar eclipse just after rounding the far side of the moon on April 6.

‘Like a Hole in the Universe’: Artemis 2 Astronaut Victor Glover Reflects on Seeing a Total Solar Eclipse While Flying by the Moon

The four astronauts who rounded Earth’s natural satellite in April got an extremely rare view of the dark lunar disk blocking out the sun. Researchers say the observations provide unique scientific value for understanding our star’s mysteries

The quake rocked Kumamoto on the Japanese island of Kyushu.

This 400-Year-Old Impenetrable Japanese Castle That Survived a Samurai Siege Just Crumbled in an Earthquake

In 1877, a force rebelling against Emperor Meiji attacked Kumamoto Castle on Japan’s southern Kyushu island
