Use a computational representation to illustrate the relationships among Earth systems and how those relationships are being modified due to human activity.
- Environment
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.
- Environment
Let’s learn about plastic pollution
The world is cluttered with plastic waste. All that junk kills animals far and wide.
- Climate
New UN climate report finds no time for denial or delay
It links extreme weather around the globe to Earth’s changing climate.
- Earth
Let’s learn about Antarctica
This continent is dry, windy and very cold — and home to penguins, ice and a lot of scientific research.
- Environment
‘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.
- Climate
U.S. records reveal the last 30 years were the hottest on record
New ‘climate normals’ show that average temperatures increased notably just since 1990.
- Earth
‘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.
- Earth
Only 3 percent of Earth’s land is unchanged by people
A sweeping survey of land-based ecosystems finds that very few still support all the animals they used to. Reintroducing lost species could help.
- Environment
Local glacier could be gone in a decade, young scientist finds
A teen calculated the volume of a glacier by drilling into it with jets of steam — then used that to estimate how long before all its ice will be gone.
- Earth
Here’s how lightning may help clean the air
Airplane observations show that storm clouds can generate huge quantities of air-cleansing chemicals known as oxidants.
- Brain
Patterns in brain activity can identify who will struggle to read
Certain patterns of brain activity predict whether teens are strong readers or will struggle. Those diagnostic patterns show up even when doing math.
