An Artificial Neural Network Joins the Fight Against Receding Glaciers

A new artificial neural network named CALFIN catalogues the rates at which glaciers are melting, demonstrating what the future of glaciology could look like.

Retreating Glaciers Threaten Herbs Used to Make Iconic Alpine Liqueurs

As glaciers recede in the Italian Alps, a shift toward grasslands is threatening native herbs like Artemisia genipi, a key ingredient in the region’s traditional liqueurs.

Study Tracks an Abrupt Climate Shift as Ice Age Glaciers Began to Retreat

That change would have affected the monsoons, today relied on to feed over half the world’s population, and could have helped tip the climate system over the threshold for deglaciation.

What Geology Has to Say About Global Warming

The most important lessons drawn from geology are that the earth’s climate can change radically, and rapidly. We can’t say precisely at what CO2 level we’re in danger of melting Antarctica, but that threshold could be reached in 150-300 years, if CO2 levels keep rising at the current rate.
