The new UN climate change report shows there’s no time for denial or delay
Human-caused climate change is unequivocally behind extreme weather events from heat waves to floods to droughts, a massive new assessment concludes.

50 years ago, scientists developed self-destructing plastic
In the 1970s, scientists developed plastic that could quickly break down when exposed to light. But that didn’t solve the world’s pollution problems.

A new book reveals stories of ancient life written in North America’s rocks
In ‘How the Mountains Grew,’ John Dvorak probes the interlinked geology and biology buried within the rocks of North America.

Greece’s Santorini volcano erupts more often when sea level drops
During past periods of lower sea levels, when more of Earth’s water was locked up in glaciers during ice ages, the Santorini volcano erupted more.

Dinosaur-killing asteroid may have made Earth’s largest ripple marks
A tsunami created by the Chicxulub impact could have formed giant ripples found in rock under Louisiana, a new study finds.

A stunning visualization of Alaska’s Yukon Delta shows a land in transition
Water and ice helped form the Yukon River’s delta. Now, climate change is reshaping it.

3.42-billion-year-old fossil threads may be the oldest known archaea microbes
The structure and chemistry of these ancient cell-like fossils may hint where Earth’s early inhabitants evolved and how they got their energy.

How intricate Venus’s-flower-baskets manipulate the flow of seawater
Simulations show that a deep-sea glass sponge’s intricate skeleton creates particle-trapping vortices and reduces the stress of rushing water.

Missing Antarctic microbes raise thorny questions about the search for aliens
Scientists couldn’t find microbial life in soils from Antarctica, hinting at a limit for habitability on Earth and other worlds.

Climate change may be leading to overcounts of endangered bonobos
A changing climate in Congo is affecting how scientists count bonobos’ nests, possibly skewing estimates of the great ape population, a study suggests.

Mixing trees and crops can help both farmers and the climate
Agriculture is a major driver of climate change and biodiversity loss. But integrating trees into farming practices can boost food production, store carbon and save species.

Hurricanes may not be becoming more frequent, but they’re still more dangerous
A new study suggests that there aren’t more hurricanes now than there were roughly 150 years ago.
