Ancient Arctic ‘gas’ melt triggered enormous seafloor explosions
Methane explosions 12,000 years ago left huge craters in bedrock on the Arctic seafloor. Scientists worry more could be on the way today as Earth’s ice sheets melt.

To study a geyser, these teens built their own
Fascinated by geysers but unable to see one? These teens decided to build their own. It allowed them to study how temperature and pressure make the water spew into a founta.

Massive ice shelf is poised to break off of Antarctica
A fast-growing crack in Antarctica’s Larsen C ice shelf could soon release a truly huge hunk of ice into the ocean.

Cool Jobs: Wet and wild weather
How’s the weather? Forecasts rely on scientists and engineers who collect and interpret data gathered on the ground, in the sky and way up in space.

Scientists Say: Hoodoo
When softer rocks are covered with a harder rock layer, weathering can wear away the softer stone. This will leave behind tall thin towers — hoodoos.

Dust creates deserts in the sky
Vast rivers of dust flow through the sky. This invisible force shapes our world in profound ways. And scientists are finally homing in on a major source.

Quake risk in some central states rivals California’s
Risks of tremors in some central U.S. states are as high as those in quake-prone California. The reason: waste fluids from oil and gas drilling.
