As a hub for research and education, the Institution is poised to help the world find solutions to the global challenge

American bumblebees are a vital pollinator for wildflowers and crops, and their decline could have severe consequences for the environment.  

The American Bumblebee Has Nearly Vanished From Eight States

In two decades, the insect's population has declined by nearly 90 percent due to a combination of threats, including habitat loss, pesticides and diseases

Plastic debris covers much of the sand on Henderson Island.

Plastics Make Beaches Hotter During the Day and Colder at Night

A study of remote islands shows that debris alters sand temperatures

Fishers gather rope and nets on a fishing boat in Gaza in May 2021. 

With Ropes and Nets, Fishing Fleets Contribute Significantly to Microplastic Pollution

Synthetic ropes release 'substantial amount' of plastic particles into the sea during each use, according to new research

A cluster of western monarch butterflies clings to a branch as it overwinters in California.

The Best Place to Watch Monarch Butterflies Migrate Might Be This Little California Beach Town

Thousands of western monarchs migrate to Pismo Beach each fall to escape winter cold, but climate change threatens the species' survival

Enticed by a sweet treat, a cow learns to use the "MooLoo," a latrine for cattle, where excrement can be collected. The only question is: can this technique work on a larger scale?

Researchers Potty Trained Young Cows, a Promising Measure to Reduce Greenhouse Gases

One cow pees up to eight gallons a day; training them is easy, and capturing and treating the waste could make a difference

Environmental scientist Alexandra Ordoñez Alvarez from the University of Queensland collects data in Far Northern Great Barrier Reef on Ashmore Bank.

Scientists Complete the First Map of the World's Coral Reefs

Nearly 100,000 square miles of the organism have been charted in high detail to create a tool for conservationists to help save them

Grizzly bears in coastal British Columbia are more closely linked to Indigenous groups than previously realized.

Grizzly Bear Territories in Canada Match Maps of Indigenous Language Families

DNA analysis shows a distinct relationship between three distinct groups of grizzlies and Indigenous populations with different languages

The creation of clouds over forested areas shows that reforestation would likely be more effective at cooling Earth’s atmosphere than previously thought, a Princeton study says.

Planting Trees Encourages Cloud Formation—and Efficiently Cools the Planet

New study examines cooling effect of clouds produced by deciduous forests under pressures of climate change

'Blue' Hydrogen May Not Be a Very 'Green' Energy Source After All

Climate scientists conclude this so-called clean alternative has a 20 percent larger carbon footprint than natural gas and coal when used for heat

This map shows how land and ocean temperatures have changed from June 2021 relative to the 1951-1980 base period. High values (darker red colors) indicate temperatures that are higher than those in the base period. The number in the top right is an estimate of the global mean temperature increase. All temperatures are in Celsius.

Study Measuring Earth's Vital Signs Warns of Climate Tipping Points

The authors say tropical coral reefs, the Amazon rainforest, and the West Antarctic and Greenland ice sheets may have passed dangerous tipping points

Feral hogs wreak havoc on the ecosystems they invade, and new research suggests they're also contributing to climate change by releasing 1.1 million cars-worth of carbon dioxide every year.

Feral Pigs Release 1.1 Million Cars-Worth of Planet-Warming Carbon Dioxide Every Year

The study's results add exacerbating climate change to the list of environmental impacts ascribed to this invasive species

Members of the public take part in a blessing of the Lummi Nation totem pole in San Leandro, California, on June 3. The House of Tears Carvers toured the pole around the West Coast before embarking on a two-week journey to Washington, D.C.
