Scientists in Antarctica discover a vast, salty groundwater system under the ice sheet – with implications for sea level rise

Liquid water below the ice determines how fast an ice stream flows. As the ice sheet gets thinner, more of that salty groundwater could rise.

Thawing permafrost is roiling the Arctic landscape, driven by a hidden world of changes beneath the surface as the climate warms

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.
Winter road salting is a common de-icing technique used to ensure public safety during icy winters. However, it is crucial to find sustainable and environment-friendly alternatives to road salt. (Shutterstock)

Winter road salting has year-round consequences

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.
The decreasing ice cover in northern lakes will severely impact the lake ecology as well as winter recreation activities in the northern region. (Shutterstock)

Our lakes are losing their ice cover faster than ever — here’s what that means for us

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.

Deportation threats for some students come from within schools

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.

Is chewing on ice cubes bad for your teeth?

A dentist explains why this is a habit worth breaking – no matter the cause or the strength of your cravings to keep doing it.

Melting Mongolian ice reveals fragile artifacts that provide clues about how past people lived

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.
