Climate

Physics

Scientists Say: Equilibrium

This steady state may look like a total standstill, but it’s actually an equal opposition of forces.

Climate

Microbes that dwell in tree bark devour major climate gases

Hidden in plain sight, this huge community of tree-bark microbes dines on gases — such as methane — that warm Earth’s atmosphere.

Environment

Antarctica faces a green and weedy future

Warming is allowing alien species to invade a land that had been isolated for 30 million years. They now threaten local ecosystems unique to Antarctica.

Climate

As winters warm, athletes must cope with harder snow and tricky ice

Ice arenas and artificial snow now dominate the winter Olympics. Athletes there — and everywhere — may need to adjust how they train and perform.

Earth

Experiment: Weather and climate in your neighborhood

In this experiment, use historical weather data to investigate how weather and climate conditions have changed in your area over time.

Animals

Polar bears leave thousands of tons of food scraps for other species

The new finding quantifies how much of polar bears' food goes uneaten. As these bears decline, Arctic scavengers risk losing a critical food source.

Climate

Global coral die-offs signal Earth’s first climate tipping point

The corals offer a dire warning, scientists say, and suggests that more such catastrophic points of no return could occur soon — some within a decade.

Earth

Cities across the world are sinking. Here’s how they might rebound

Affected coastal cities tend to flood more often — a growing threat in this era of continuing sea level rise.

Environment

During heat waves, trees spew chemicals that worsen air pollution

New data point to how heat waves and other climate change will make it harder to curb ozone and other types of toxic air pollution — even outside of cities.

Environment

See how aerosols fly through Earth’s skies

These small airborne particles may offset one-third of human-caused climate warming. But the cooling influence of aerosols is fading.

Earth

Scientists Say: Heat dome

Typically, weather enters an area, storms through, then leaves. Here's what happens when steamy summer air gets stalled.

Agriculture

A secret climate superhero lies beneath our farms

Agriculture contributes to climate change. But changes to how farms manage soil might help remove carbon and other greenhouse gases from the air.
