Bits of airborne salt may help raindrops form, removing water from clouds before it can freeze as part of the process that makes lightning.
Inland melting of the Northeast Greenland Ice Stream is accelerating — and may contribute far more to sea level rise than earlier estimates suggested.
It appears the Pine Island and “Doomsday” Thwaites glaciers are losing ice — and shrinking faster — than at any time in the past 5,500 years.
The device not only produces electricity but also harvests water for drinking or crops. It could be especially useful in remote and dry parts of the world.
Groundwater provides drinking water to billions of people and is used to water crops worldwide.
The ice shelf that had kept it in place could fail within five years. That would speed the glacier’s slip into the ocean, boosting a rise in sea levels.
Smoke drifts. Fish eggs float downstream. Where such drifting things end up may seem a mystery. But research can predict where they’ll end up.
