Scientists have planted American trees in China, Korea and elsewhere to attract hungry insects. Their hope is to identify the most damaging bugs before they cross the ocean.

In northern Norway, Sami people fear a copper mine will disrupt their traditional lifestyles.

Melanie Malone led a research project to identify and study contamination sites in Washington State. Then the E.P.A. canceled her grant.

Large fires, fueled by a record breaking drought, have been destroying homes and timber plantations in Southeastern states.

Researchers examined the combined effects of tree loss and global warming in an effort to better understand how and when an ecosystem collapse could unfold.

In 2025, the world razed less forest than any other year in the last decade. The bad news: global warming is making wildfires more frequent and intense.

The new federal office will undo a change made after the 2010 Deepwater Horizon oil disaster. Critics say it could reduce environmental oversight.

The new deep-sea atlas underscores Beijing’s interest in ocean mining, its military ambitions and its claims to disputed waters.

Scientists long believed it would take more than a century for animals to return to deforested land. New research shows that’s not always the case.

The animals might be entering the Bay in search of food as climate change disrupts traditional sources. They face huge risks from ships in the area.

A record-mild winter and blistering spring heat will mean higher risks of water shortages and wildfires in the months ahead.

A new satellite could transform how water is studied worldwide. But to help unlock its capabilities, scientists first needed to take critical measurements on a mountaintop.

A record-breaking snow drought has residents worried about much more than slushy slopes.

An unusual outbreak of wildfires in city parks gave scientists a chance to study these rare events. Now they’re coming to different conclusions.

Researchers found that a majority of studies on coastal sea levels underestimated how high water levels are, and hundreds of millions of people are closer to peril than previously thought.

Leticia Carvalho heads a global authority that’s been struggling to set rules for a decade. President Trump’s aggressive push on ocean mining makes her task more urgent.

Elon Musk wants to launch a million satellites, but researchers say global warming is changing the upper atmosphere in ways that makes space junk linger.
