Smoke drifts. Fish eggs float downstream. Where such drifting things end up may seem a mystery. But research can predict where they’ll end up.
El Niño and La Niña are part of a climate cycle that results in major weather changes every few years.
Scientists are seeking to understand why and how to mop up excess precipitation.
Cities transform landscapes covered in plants to ones covered in heat-absorbing asphalt and concrete. But ways exist to cool these urban heat islands.
Around 100 times a second, every hour of every day, lightning strikes somewhere on Earth. It’s beautiful — and deadly.
Airplane observations show that storm clouds can generate huge quantities of air-cleansing chemicals known as oxidants.
Simple route changes could drastically cut fuel use and greenhouse-gas emissions, a new study finds.
We may not see them, but tiny particles and droplets cloud the air, affecting its properties. Some may be pollutants, others all-natural products.
Severe wildfires are becoming more common. Science is showing that the tiny particles they release into the air can alter Earth’s temperature — sometimes cooling it.
