Let’s learn about snow
Snow is more than just frozen water vapor. Scientists are studying everything from its shape to other planets where snowflakes fall.

Surprising long-haul dust and tar are melting high glaciers
Dust and tar blown onto high mountains, like the Himalayas, boost the melting of snow and ice far more than scientists had realized. Here’s why.

Soggy coastal soils? Here’s why ecologists love them
Coastal wetlands can protect our shores from erosion, flooding and rising sea levels.
- Environment
Here’s one way to harvest water right out of the air
Need water but you have no access to rain, lakes or groundwater? Materials known as metal-organic frameworks could be used to slurp that water from the air, new data show.

Explainer: How is water cleaned up for drinking
Unless you’re drinking well water, city folks typically get drinking water that has been treated in a water-treatment plant. Here’s what that means.

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.

Antarctic ice shelf sheds Delaware-sized iceberg
Larsen C is a major ice shelf in Antarctica. An iceberg the size of Delaware has just splintered off of it in one of the largest calving events ever recorded.

Teen’s invention can warn of deadly rip currents
A teen lifeguard from Australia has invented a buoy that can alert swimmers to the strong, swift and deadly rip currents that can sweep them dangerously far offshore.

Arctic Sea could be ice-free by 2050
Everyone contributes to the melting of Arctic sea ice, and all are in danger of making summer ice disappear there completely by 2050, a new study finds.
