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.
Global governance of artificial intelligence is necessary to regulate AI industries.

De-icing salts help us get around in winter, but they corrode cars, crack roads and contaminate rivers and lakes. Scientists are working to develop better options by imitating natural antifreezes.
Ice with a slice of history.

The history of ice in drinks goes back to antiquity. But it only really got going when a Bostonian started exporting ice to the British in colonial India.
The Perito Moreno glacier in Patagonia. The sheer number of seracs gives the impression that the glacier’s surface is covered in dragon scales.

The parable of the dragons underlines the need to apprehend glacier disappearance in a transdisciplinary way, to create a dialogue between the physical, ecological and philosophical sciences.
Fossil remains indicate these birds had a wingspan of over 20 feet.

Paleontologists have discovered fossil remains belonging to an enormous ‘toothed’ bird that lived for a period of about 60 million years after dinosaurs.
As Greenland’s glaciers retreat, they are losing ice at a faster and faster rate.
Michalea King
Greenland’s glaciers have retreated so far that they can no longer support the ice sheet that feeds them. The ice sheet system has reached a new normal of consistent annual ice loss.
The Zimovs want to restore the prehistoric ‘mammoth steppe’ ecosystem and see if it slows down – or even reverses – melting permafrost.
This Arctic heat wave has been unusually long-lived. The darkest reds on this map of the Arctic are areas that were more than 14 degrees Fahrenheit warmer in the spring of 2020 compared to the recent 15-year average.

Love it or hate it, winter means snow and ice for much of the US. In many places, though, snow is becoming a scarce resource.
Kimora Adetunji, 33, is seen with her son King, 2, outside Federal Court in Toronto in May 2017, where indefinite immigration detention was subject of a court hearing. Her husband was detained for almost a year before being released.

Migration governance without immigration detention is desirable and achievable. Eliminating all detention will universally benefit citizens, migrants and everyone in between.
Fixing cracks and potholes in concrete roads like this one may be easier with help from bacteria.
Yaghoob Farnam
Patching concrete sidewalks, roads and bridges after every season of snow and ice is expensive. A team of engineers is now testing a new approach harnessing bacteria to patch the potholes and cracks.
Spraying salt onto roads is a safety measure.

An atmospheric scientist explains why water can do some strange-looking things at very cold temperatures, and what’s different about snowfalls on Mars.
Sea ice responds to changes in winds and ocean currents, sometimes with origins thousands of kilometres away.

Antarctic sea ice cover fell to an all-time low recently and hasn’t yet recovered. Why? The initial answers could lie in an unlikely place – the tropics.
