Scientists Say: Anthropocene
Humans are changing the world in profound ways. Some scientists think those changes have launched a new epoch in Earth’s history: the Anthropocene.

Synthetic trees could tap underground water in arid areas
They also could also help coastal residents mine fresh water from salty sources.

Tiny animals survive 24,000 years in suspended animation
Tiny bdelloid rotifers awake from a 24,000-year slumber when freed from the Arctic permafrost.

Wildfire smoke seeds the air with potentially dangerous microbes
Studies now show that most wildfires don’t kill microbes. That’s fueling worries about what risks these smoke hitchhikers might pose to people.

Greece’s Santorini volcano erupts more when the sea level drops
Data showing this association go back at least 360,000 years.
- Climate
Warming cities may see more rain — and frequent flooding
Scientists are seeking to understand why and how to mop up excess precipitation.

Explainer: Urban heat islands and how to cool them
Cities transform landscapes covered in plants to ones covered in heat-absorbing asphalt and concrete. But ways exist to cool these urban heat islands.

‘Zombie’ wildfires can reemerge after wintering underground
Climate change may make these not-quite-dead blazes more common. Scientists are learning to predict where a zombie might emerge.
- Animals
Sudden shark die-off 19 million years ago eliminated most species
New fossil evidence shows 90 percent of sharks died in the mysterious event.

Let’s learn about dinosaurs’ fearsome neighbors
Dinosaurs may get much of our attention, but there were plenty of other interesting critters during the Age of Reptiles, including our mammal ancestors.

‘Tree farts’ make up about a fifth of greenhouse gases from ghost forests
Heat-trapping gases from dead trees play an important role in the environmental impact of “ghost” forests.
