Ground is collapsing and massive lakes are draining in a matter of days. Thawing permafrost is having profound effects on the region and its infrastructure.
Several states are experimenting with weather modification to try to generate snow as water supplies shrink. An atmospheric scientist explains the history behind it – and the challenges.
Across the solar system, asteroids and comets crash into moons and planets every day. The rocket collision will provide researchers with important data on how these collisions work.
It may look like athletes in bobsled, luge and skeleton simply grab a sled and hang on until the bottom, but high-speed physics and tiny motions mean the difference between gold and a crash.
Salty water seeps into our soils and groundwater through surface runoff and storm-water pipes. The long-term storage of salt in the environment impacts aquatic life, infrastructure and drinking water.
Lakes in the northern hemisphere are rapidly losing their ice cover due to rising greenhouse gas emissions. The only way to preserve lake ice is to limit GHG emissions and slow down climate change.
Researchers say educators told them that immigrant students are sometimes made to believe they will be deported. Why? One reason is educators didn’t want them to drag down their school’s test scores.
From the high Yukon to the mountains of Central Asia, melting ice exposes fragile ancient artifacts that tell the story of the past – and provide hints about how to respond to a changing climate.
