At the 2023 EGU General Assembly, our cryosphere division members all voted “YES!” to have a division policy point of contact! If you’re wondering how to engage in science policy at our division level, what a division policy officer does, who was named and what happened next… This blog post should answer a lot of …[Read More]
Ice sheet models are awesome tools that help us learn and predict the fate of ice sheets under human-induced climate change. However, all models have errors. What types of uncertainties exist in an ice sheet model and how can we quantify some of them efficiently? Check out our recipe to quantify one type of uncertainty …[Read More]
In this week’s blog, Levan Tielidze tells us about the first inventory of rock glaciers from the Greater Caucasus as an important basis for further research of geomorphology and palaeoglaciology in this region. What are Rock Glaciers? Rock glaciers are distinctive geomorphological landforms of frozen debris that are supersaturated with ice. The low ice velocity …[Read More]
Darkness. Freezing cold. Thin layers of ice cover the wide Arctic Ocean. It is the time of the last dusk. You can almost see Fenris wolf chasing the sun to devour it, almost hear his howling as darkness falls. Fimbulwinter has arrived. But what is this? A flower? Out here on the Arctic Ocean? This …[Read More]
Each year, the Arctic sea ice goes through a cycle of melting and freezing. From March to September, sea ice gradually melts and becomes thinner, and from October to March, the water freezes again. In our warming climate, we see that more and more ice melts each year. One would expect that the ice would …[Read More]
Does measuring the surface of the ice sheets provide more than superficial knowledge of their current status? Read further to find out why the answer is definitely yes! Measuring surface elevation changes actually tells us where Greenland and Antarctica are thinning or thickening and how much they contribute to sea level rise. Scientists have been …[Read More]
We are getting used to perceiving glaciers more and more distant and disconnected from our mountains. With each passing year, it is more difficult to observe them, reach them or climb them. They are becoming an exotic element of the Alpine imagination. When our gaze rests on a mountain glacier, with its crevasses and large …[Read More]
In high-school, I learned in a textbook that glaciers are melting. My teacher said that what was written in that textbook was right, and that was it. There was no proof, no explanation, no scientist’s testimony. All of that, I discovered much later during my studies in the geosciences. Yet as the global temperatures keep …[Read More]
Hidden beneath the surface of ice sheets lies an intricate structure carrying a unique fingerprint of past ice flow and climate conditions. Disentangling the drivers of an ice sheet’s enigmatic stratigraphy could theoretically unravel the ice sheet’s past evolution and provide a much clearer picture of things to come in the future. One way to …[Read More]
Around the summer solstice of 2022, a small group of twenty young researchers met in Svalbard, a small island lost between Norway and the North Pole. The Norwegian Scientific Academy for Polar Research wanted to bring us together around the theme of “The Global Arctic“. The scope of this summer school was to “produce a …[Read More]
