Earth Headed for Nearly Three-Degree Temperature Hike—Well Above Paris Agreement Level

A new U.N. report finds current pledges put the planet on track to warm 2.5 to 2.9 degrees Celsius above pre-industrial levels this century

Green sea turtles are struggling because of climate change, habitat destruction, erosion and other threats.

Metal Pollution May Be Making More Green Sea Turtles Female

In addition to warming temperatures, new research finds contaminants might contribute to the endangered reptiles' skewed sex ratios

By 2030, coal production is projected to rise to 460 percent above what’s consistent with limiting warming to 1.5 degrees Celsius.

World governments are planning to produce 110 percent more coal, oil and gas in 2030 than is allowed under the Paris Agreement, U.N. says

Wildfires have smashed records this year in Canada, scorching more than 40 million acres in the country.

Earth Is Entering 'Uncharted Territory' Because of Climate Change, New Report Warns

Researchers found that 20 of 35 "planetary vital signs" are at record extremes, and they call for rapid action

Atlantic salmon spend most of their lives in the cool waters of the ocean. When they venture upstream in freshwater rivers to spawn, however, they encounter challenging warmer waters.

Engineers Create 'Air Conditioning' for Salmon With Chilled Patches of River Water

Wild Atlantic salmon can struggle with heat as they swim upstream to spawn—but artificial "thermal refuges" may help them cool off

Hurricane Otis caused major damage in Acapulco, Mexico.

Hurricane Otis Slams Mexico in 'Nightmare Scenario' That Shocked Meteorologists

The storm rapidly intensified in just 24 hours before it hit Acapulco as a category 5, killing at least 27 people and destroying infrastructure

A chum salmon in Alaska's Katmai National Park and Preserve. Salmon numbers are declining in some places due in part to climate change.

Climate Change Is Pushing Salmon North in Alaska, Scientists Say

Researchers recently found about 100 chum salmon spawning in the Arctic, suggesting the species is shifting to new habitats

Ice shelves are important because they help keep ice on land from flowing into the ocean as quickly.

Rapid Melting of West Antarctic Ice Shelves Is 'Unavoidable,' Study Finds

Even under a best-case climate scenario, global sea levels will likely rise because of this accelerated melting, scientists say

Hops give beer its bitter taste and aroma.

Hoppy Beer Could Be Climate Change's Next Victim

Warming temperatures and drier conditions in Europe could continue to lead to declines in hop yields and hop quality, a new study finds

Sheets of ice on top of the ocean in the Antarctic, photographed in February 2000. Sea ice reflects most of the sun's radiation that hits it, keeping the polar regions cool.

Antarctic Winter Sea Ice Hits a Record Low 'by a Wide Margin'

On September 10, the ice reached its lowest annual maximum in the books amid a record-smashing year that's ringing "alarm bells" for polar ice

Warming spurred by Earth's next supercontinent could lead to widespread desert conditions, a new modeling study suggests. Pictured is the Tengger Desert in Inner Mongolia, an autonomous region of China.
