Particles in air help fatten clouds’ water droplets
Making their own clouds has shown scientists how the fattest water droplets form. Understanding this could lead to better forecasts of climate change.

Enormous natural-gas leak polluted L.A. air
A massive methane release from a single leaky underground well spewed as much of the greenhouse gas into the air as a mid-sized European country does in an entire year.

Cool Jobs: The power of wind
Science and engineering careers explore all aspects of wind, from terrible tornadoes to aeronautics and clean energy.

Sea level rising fastest in 2,800 years
The oceans rose faster during the 20th century than any time in the past 2,800 years. More than half of the rise came from global warming.

Cool Jobs: Careers on ice
From Greenland to Utah to Jupiter, scientists unlock mysteries frozen in ice.

A shock to the food system
Droughts and other weather extremes caused by climate change are dramatically increasing the risk of short-term interruptions in the supplies of food.

2015 was really hot
Spurred by global warming and a “super” strong El Niño, 2015 went into the books as the warmest year since record-keeping began — and that was 1880.

Arctic ice travels fast, carrying pollution
Climate change is melting old sea ice in the Arctic. Now, younger, thinner ice is migrating far and fast, taking pollutants with it.

Paris meeting yields climate agreement
It provides outlines and incentives for nations to curb fossil-fuel use. The goal is to limit global warming to no more than 2° Celsius (3.4 °Fahrenheit) above temperatures typical in the 1750s or earlier.

Carbon dioxide has an unexpected effect in Antarctica
Antarctica’s frigid surface combined with excess carbon dioxide to create cooling above the remote continent, a new study finds.

Concerns about Earth’s fever
Burning fossil fuels is causing the planet to heat up, causing weather patterns to change, sea levels to rise and diseases to spread.

Explainer: How scientists know Earth is warming
Scientists can calculate global temperatures, both present and past. Their findings show that the planet is rapidly heating up.
