Glass microspheres aren't the answer for saving Arctic sea ice

A proposal to cover Arctic sea ice with layers of tiny hollow glass spheres about the thickness of one human hair would actually accelerate sea-ice loss and warm the climate rather than creating thick ice and lowering the ...

Listening to the song of melting glaciers

This is it, we have reached the bottom of the glacier. It is 327m under our feet. After drilling into the ice for six hours, our hot-water jet blasts into the sediment. The hose that connects it to the surface stops rolling ...

Are we missing a crucial component of sea-level rise?

Recent efforts using computational modeling to understand how melting ice in Antarctica will impact the planet's oceans have focused on ice-sheet geometry, fracture, and surface melting—processes that could potentially ...

Why don't rivers straighten out over time?

Seen from above, the world's greatest rivers can be recognized by their serpentine curves. But how do these shapes form, do they alter over time and does this matter? We turned to our river system expert, Carmelo Juez.
