Ocean Sponge Skeletons Suggest a More Significant History of Global Warming Than Originally Thought

Analysis of the sea creatures’ skeletal chemistry suggests the world’s temperatures have increased by 1.7 degrees Celsius since pre-industrial times

An entire neighborhood in Tacloban, Leyte, Philippines, destroyed by Typhoon Haiyan in 2013. More than 6,500 people died during the storm, which had maximum sustained winds of 195 miles per hour. Winds of those speeds would be above the threshold for a hypothetical Category 6 for tropical cyclones proposed by researchers.

Do We Need a Category 6 Designation for Hurricanes?

Global warming is leading to more intense storms well above the threshold for Category 5 hurricanes, scientists write in a new paper

For the second year in a row, the clock is the nearest it has ever been to signaling our total annihilation

Kelp cultivated in underwater forests could help curb climate change, both because of the carbon these forests capture and because products made from kelp can reduce carbon emissions.

Could Sinking Tons of Seaweed to the Ocean Floor Help Combat Climate Change?

Submerged seaweed can store carbon at the bottom of the sea, but how effective the strategy will be remains unclear

Bottom trawling is a polarizing fishing practice that involves dragging heavy nets and equipment across the seafloor.

Seabed Trawling May Be Spewing Huge Amounts of CO2 Into the Atmosphere

New research suggests the controversial fishing method is also contributing to increased ocean acidification, which can harm marine wildlife

Researchers studied roughly 50 numbats over the course of a year.

As the Planet Warms, Australia's Numbats Are at Risk of Overheating

The endangered, squirrel-sized marsupials forage for termites during the day—but they can become too hot after just ten minutes in direct sunlight, according to new research

Researchers measure California snowpack levels at Phillips Station in the Sierra Nevada on January 2.

Climate Change Is Melting Snowpack, Pushing Some Regions Past a 'Snow-Loss Cliff'

Some of the Northern Hemisphere's most populous areas are at risk of warming past a critical threshold, after which snowpack melts rapidly with even small rises in temperature, study finds

In the extreme heat of summer 2023, saguaro cactuses died in Arizona.

2023 Broke Temperature Records. Will 2024 Be Even More Extreme?

Climate scientists have confirmed that last year's heat was unprecedented, surpassing records by a wide margin—but it could be one of the coolest years to come
