An artificial neural network joins the fight against receding glaciers

What makes a neuron? In the 1940s, at the dawn of the computer age, researchers gave the word a second meaning. In the case of neural networks, the artificial neurons comprising them are more simple than one might expect: ...

Glacier avalanches more common than thought

One tends to think of mountain glaciers as slow moving, their gradual passage down a mountainside visible only through a long series of satellite imagery or years of time-lapse photography. However, new research shows that ...

What a glacial river reveals about the Greenland Ice Sheet

With data from a 2016 expedition, scientists supported by NASA are shedding more light into the complex processes under the Greenland Ice Sheet that control how fast its glaciers slide toward the ocean and contribute to sea ...

Evidence of Antarctic glacier's tipping point confirmed for first time

Researchers have confirmed for the first time that Pine Island Glacier in West Antarctica could cross tipping points, leading to a rapid and irreversible retreat which would have significant consequences for global sea level.

Lakes on Greenland Ice Sheet can drain huge amounts of water, even in winter

Using satellite data to 'see in the dark', researchers have shown for the first time that lakes on the Greenland Ice Sheet drain during winter, a finding with implications for the speed at which the world's second-largest ...

Model for predicting mountain snowpack provides clearer picture of spring runoff, impacts of climate change

After decades of research, a new model was developed by University of Saskatchewan (USask) researchers that for the first time successfully predicted mountain snowpack with a high degree of accuracy and detail—information ...

Air pollution fell sharply during lockdown

The far-reaching mobility restrictions at the beginning of the COVID pandemic in March 2020 created a unique situation for atmospheric sciences: "During the 2020 lockdown, we were able to directly investigate the actual effects ...
