In a new analysis, researchers estimated direct, indirect and future greenhouse gas emissions that were created in the first two weeks of the Iran war, between Feb. 28 and March 14.

Antarctica could warm much faster than its surroundings over the next few decades due to a phenomenon known as polar amplification that is well established in the Arctic.

Researchers have captured extraordinary footage of sperm whales randomly headbutting each other, confirming anecdotal reports from mariners and whalers in the 18th and 19th centuries.

In a recent opinion article, marine scientists and electrochemists listed a number of reasons why it's unlikely that metallic nodules on the deep seafloor could produce oxygen in total darkness.

A landmass that once connected Britain to mainland Europe had temperate forests that could have sustained Stone Age people for millennia before the landmass was flooded, a new study suggests.

Carbon that has been buried in the Congo Basin's peatlands for millennia is seeping into lakes and rivers. Why this is happening remains unclear, but researchers warn that tropical peatlands could be nearing a tipping point.

Shifts in the Gulf Stream could help researchers predict the human-driven failure of a huge system of ocean currents known as the Atlantic Meridional Overturning Circulation.

The pygmy long-fingered possum and the ring-tailed glider, two marsupials believed to have died out thousands of years ago, are still alive in Papuan Indonesia.

An analysis of peatland soil samples and satellite images has found that wildfires on Alaska's North Slope are more frequent and severe now than they were at any point over the past 3,000 years.

Huge-scale ecological engineering around the edges of one of the world's largest and driest deserts has turned it into a carbon sink that absorbs more CO2 than it emits, research suggests.

Earth's core contains nine to 45 times more hydrogen than the planet's oceans do, according to a new study that could settle a debate about when and how hydrogen was delivered to Earth.

Advanced modeling has revealed an Australia-shaped magnetic anomaly beneath the country's Northern Territory that holds valuable information about Australia's geological history.

Here are the 24 images shortlisted for the Wildlife Photographer of the Year Nuveen People's Choice Award 2026.

An image of polar bears napping along the Hudson Bay coast in Canada has been shortlisted for the Wildlife Photographer of the Year Nuveen People's Choice Award 2026.

Millions of years ago, the Green River carved a path through the Uinta Mountains instead of flowing around the formation. Now, researchers have discovered how this could have happened.

Dams in the U.S. are showing signs of damage that are worsening with age and climate change. Could satellites help prioritize repairs amid budget and inspection constraints?

In 1963, researchers unearthed two Stone Age skeletons that were buried in an embraced position in a cave in Italy. Now, DNA testing has revealed that one of them had a rare genetic condition.

A new analysis of mineral grains has refuted the "glacial transport theory" that suggests Stonehenge's bluestones and Altar Stone were delivered to Salisbury Plain by glaciers.

An expedition off the coast of Massachusetts has confirmed the existence of a freshwater reservoir beneath the seafloor. Now, scientists are starting to understand when and how it formed.

Worldwide, millions of people live in river deltas that are sinking faster than sea levels are rising, research suggests. This exacerbates the risk of catastrophic coastal flooding and land loss.

Scientists recently discovered a new species of green anaconda in the Amazon rainforest. A new Nat Geo series shows the moment they encountered this snake in the wild.
