Today is International Women’s Day. As three early career glaciologists, we set out to investigate the state of gender diversity in the cryospheric sciences. Is there a better day for this than the day of recognition of the fight for women’s rights across the globe? “The extreme nature of high alpine and polar environments made the rhetoric of mountaineering and glaciology heroic and masculine, wh ...[Read More]
Image of the Week – Why is ice so slippery?
Having spent most of my life in places where the temperature hardly ever falls below zero, my first winter in Sweden was painful. Especially for my bum, who met the ice quite unexpectedly. Reading the news this week, from reports of emergency services overwhelmed after so many people had slipped to a scientific study on how no shoes have a good enough grip, via advice on how to walk like a penguin ...[Read More]
Ice-hot news: The cryosphere and the 1.5°C target
Every year again, the Conference of Parties takes place, an event where politicians and activists from all over the world meet for two weeks to discuss further actions concerning climate change. In the context the COP24, which started this Monday in Katowice (Poland), let’s revisit an important decision made three years ago, during the COP21 in Paris, and its consequences for the state of the cryo ...[Read More]
Image of the Week – Climbing Everest and highlighting science in the mountains

Dr Melanie Windridge, a physicist and mountaineer, successfully summited Mount Everest earlier this year and has been working on an outreach programme to encourage young people’s interest in science and technology. Read about her summit climb, extreme temperatures, and the science supporting high-altitude mountaineering in our Image of the Week. It’s bigger than it looks! Experiencing the majesty ...[Read More]
Image of the Week – Inspiring Girls!

What, you may ask, are this group of 22 women doing standing around a fire-pit and what does this have to do with the EGU Cryosphere blog? This group of scientists, artists, teachers, and coaches gathered 2 weeks ago in Switzerland to learn how to become instructors on an Inspiring Girls Expedition. But what, you may ask again, is an Inspiring Girls Expedition? Well read on to find out more… ...[Read More]

Early career scientists studying polar climate are one lucky group! The 29 young scientists who took part in the 10 day Polar Prediction School this year were no exception. They travelled to Arctic Sweden to learn and discuss the challenges of polar prediction and to gain a better understanding of the physical aspects of polar research. The Year of Polar Prediction The Year of Polar Prediction (YO ...[Read More]
Image of the Week — Biscuits in the Permafrost
In Svalbard, the snow melts to reveal a mysterious honeycomb network of irregular shapes (fig. 1). These shapes may look as though they have been created by a rogue baker with an unusual set of biscuit cutters, but they are in fact distinctive permafrost landforms known as ice-wedge polygons, and they play an important role in the global climate. Ice-wedge polygons: Nature’s biscuit-cutter In wint ...[Read More]
Image of the week — Making pancakes
It’s pitch black and twenty degrees below zero; so cold that the hairs in your nose freeze. The Arctic Ocean in autumn and winter is inhospitable for both humans and most scientific equipment. This means there are very few close-up observations of sea ice made during these times. Recently, rapidly declining coverage of sea ice in the Arctic Ocean due to warming climate and the impending likelihood ...[Read More]
Image of the Week – Super-cool colours of icebergs

It is Easter weekend! And as we do not want you to forget about our beloved cryosphere, we provide you with a picture nearly as colourful as the Easter eggs: very blue icebergs! What makes them so special? This is what this Image of the Week is about… What are icebergs made of? Icebergs are chunks of ice which break off from land ice, such as glaciers or ice sheets (as you’ll know if you rem ...[Read More]
Image of the Week – The colors of sea ice
Thin sections of sea ice photographed under polarized light. Individual ice crystals are shown by different colors. The color is random – it does not tell us anything specific about the crystals. Examples of granular ice, with smaller crystals in the top parts of the ice samples, are shown in the top rows. Columnar ice, with long layered ice crystals, can be seen in the bottom rows. Several pictures with columnar ice have air bubbles, for example all pictures in the left column and the center right picture [Credit: Polona Itkin and Anja Rösel, Norwegian Polar Institute].
The Oscars 2018 might be over, but we have something for you that is just as cool or even cooler (often cooler than -20°C)! Our Image of the Week shows thin sections of sea ice photographed under polarized light, highlighting individual ice crystals in different colors, and is taken from a short video that we made. Read more about what this picture shows and watch the movie about how we got these ...[Read More]
