Tropical cyclones are getting more sluggish

Hurricanes and other storms are traveling more slowly than they used to. That might mean even more rainfall for communities they batter.

Hurricane Maria’s Puerto Rican death toll skyrockets 72-fold

The death toll had been just 64 — and then scientists launched household surveys. Those showed the “official” toll was off by more than 4,500.

Ocean heat waves are on the rise — and killing coral

Ocean heat waves are becoming hotter and more frequent. And one can be blamed for the 2016 coral deaths on the Great Barrier Reef.

Analyze This: Climate change could make food less healthy

Levels of important nutrients are lower in crops exposed to high levels of carbon dioxide, a greenhouse gas. How high? Try levels expected to be typical 30 years from now.

Explainer: What is thundersnow?

Wacky weather produced lots of thundersnow during New England’s recent winter storms. Some scientists now suspect Mother Nature got some human help.

Climate

Super-tiny pollutants may help fire up fierce storms

Tiny pollutant particles floating in air may help create clouds and wind, strengthening storms.

Animals

Rising carbon dioxide could leave tiny lake dwellers defenseless

Rising carbon dioxide in freshwater lakes may change how predators and prey interact.

Explainer: Winds and where they come from

Temperature and pressure are critical factors affecting why the wind blows where it does. Understanding the nature of wind can teach us a lot about weather.

Scientists at last link some extreme weather to human activities

Scientists say that research shows several of 2016’s extreme weather events would never have happened without the help of human-caused climate change.
