Scientists see stronger evidence of slowing Atlantic Ocean circulation, an ‘Achilles’ heel’ of the climate

The Atlantic meridional overturning circulation, a system of currents, has long been considered capable of a sudden shutdown, which could have dramatic climate effects.

How rivers in the sky melted Antarctic ice

New research is causing scientists to rethink how polynyas—massive holes in the sea ice—are formed.

What a 1900s wildlife survey reveals about climate change

A century ago, a biologist counted California's desert animals. Now researchers are retracing his steps—and the results are surprising.

A new 3D model bolsters the case that climate change is causing mysterious Siberia craters

A 3D model of a massive 30-meter-deep crater on the Siberian tundra supports scientists previous suspicion that climate change is behind the explosions that form such craters.


Climate change: West Antarctica's Getz glaciers flowing faster

Satellites record the speed-up of glaciers along a 1,000km stretch of Antarctic coastline.

Border disputes threaten climate science in the Himalayas

Cross-border teams of scientists collaborate on climate models, even as their countries' militaries clash.

Deadly floods in India point to a looming climate emergency in the Himalayas

A massive surge of rock, debris, and icy water killed more than 50 people in Uttarakhand this month. Nearly 150 others are still missing.

Cost of Canadian science ship jumps from $108 million to nearly $1 billion

The offshore oceanographic science vessel (OOSV) will be outfitted with equipment for marine and scientific research on ocean currents and the seabed.


Swamp sentinels

Buried in mud for millennia, some of New Zealand's ancient kauri trees are revealing surprising clues about Earth's climate—past, present, and future.

Same force behind Texas deep freeze could drive prolonged heat waves

Long-lasting heat waves can be deadly. A new study suggests a warming Arctic could drive more of them in the future.

Sea level rising more rapidly: ‘Report Cards’

The recently released U.S. Sea-Level Report Cards from William & Mary's Virginia Institute of Marine Sciences show that not only are seas rising faster, the acceleration rate is increasing.


Scientists find unexpected animal life far beneath Antarctica’s floating ice shelves

Scientists discover types of sea-sponges living in the pitch-black seawater beneath half a mile beneath the Filchner-Ronne ice shelf.

Fractured: The stress of being surrounded

Jane Worthington moved her grandkids to protect them from oil and gas wells—but it didn't work. In US fracking communities, the industry's pervasiveness causes social strain and mental health problems.

Fractured: Distrustful of frackers, abandoned by regulators

"I was a total cheerleader for this industry at the beginning. Now I just want to make sure no one else makes the same mistake I did. It has ruined my life."

Fractured: Buffered from fracking but still battling pollution

A statewide network of fracking and conventional wells, pipelines, and petrochemical plants closes in on communities.

Fractured: Harmful chemicals and unknowns haunt Pennsylvanians surrounded by fracking

We tested families in fracking country for harmful chemicals and revealed unexplained exposures, sick children, and a family's "dream life" upended.

Fractured: The body burden of living near fracking

EHN.org scientific investigation finds western Pennsylvania families near fracking are exposed to harmful chemicals, and regulations fail to protect communities' mental, physical, and social health.

LISTEN: Kristina Marusic discusses the "Fractured" investigation

"Once they had the results of our study [families] felt like they had proof that these chemicals are in their air, their water, and making their way into their bodies."
