Global coral die-offs signal Earth’s first climate tipping point
The corals offer a dire warning, scientists say, and suggests that more such catastrophic points of no return could occur soon — some within a decade.

Scientists Say: Space junk
High-velocity space junk threatens space missions today. And the problem is growing.

During heat waves, trees spew chemicals that worsen air pollution
New data point to how heat waves and other climate change will make it harder to curb ozone and other types of toxic air pollution — even outside of cities.

Save the sharks to save the ocean
Humans have driven sharks and their cousins to the brink of extinction, but it’s not too late to turn the tide. At stake is the health of the entire ocean.

See how aerosols fly through Earth’s skies
These small airborne particles may offset one-third of human-caused climate warming. But the cooling influence of aerosols is fading.

Scientists Say: Heat dome
Typically, weather enters an area, storms through, then leaves. Here's what happens when steamy summer air gets stalled.

Freshwater fish are in trouble: Here’s how we can help them
Human activities threaten the survival of many freshwater fish species. Research is now pointing to how we can best overcome those threats.

More and more, microplastics are collecting in our brains
Over eight years, the mass of microplastics in human brains increased by some 50 percent. There are growing hints that internal microplastics may harm us.
