As a reader of the Cryosphere blog, you may have spent a lot of time looking at the Greenland Ice Sheet, but do you really know what Greenland looks like? This “It Ain’t Easy Being Greenland” map is something I made for fun during the #30DayMapChallenge (an international project to complete one map a day during the month of November) and highlights how different the island country appears dependin ...[Read More]

CryoNews – The WMO is making the cryosphere a global priority

To us, the cryosphere has always been a priority. It is our field of interest, research, maybe passion, it is the stuff that gets us excited. Now, the cryosphere also became a priority to the World Meteorological Organisation (WMO). In today’s post we cover a recent news item introducing this very decision made during WMO’s recent congress. Read along to find out  why they emphasize the importance ...[Read More]

Do you think that it is sometimes challenging to understand science (as a reader or listener) or to explain it (as a scientist)? Then, art may be a good solution to the problem. Between April and June 2023, Zacharie Bodson (artist) and I (climate scientist) are participating in the Seas and Oceans exhibition to explain the links between changes in Arctic sea ice and over-consumption. Read here abo ...[Read More]

As scientists, we often encounter errors in our own work and in the work of others. As modelers, we call these errors “bugs”. Of course, they are not actual insects, but they definitely keep us awake from time to time. Even though everyone is aware of their existence, we rarely discuss them in a scientific context. In today’s post, I bring to you the work and journey of a snow scientist, Dr. Cécil ...[Read More]

Did you know about Antarctic snow megadunes?

Maps showing areas on East Antarctica that have megadunes made of snow and ice.

When we think of dunes our thoughts automatically go to deserts and sand. But on Earth, as well as on other celestial bodies of the solar system, dunes exist also in a completely different environment. I am talking about gigantic dunes consisting of snow. On Earth they are called megadunes and you can find them only in East Antarctica, where they extend for thousands of km. If you want to know mor ...[Read More]

Fostering connections with frozen landscapes

Fostering connections with frozen landscapes

Whether they are natural occurrences or experimentally induced, permafrost and Arctic ecosystems are responding fundamentally to recent climate extremes. Good writing and statistics material for us scientists, but bad news on pretty much every other level. Are we effectively communicating how fundamental these changes are? And can we use our personal experiences, stories and artwork to support us ...[Read More]

The Himalayas are Big. But how Big is the fieldwork experience? What is behind all the mountain field data and beautiful mountain pictures? 40 preparation emails, 110 km of hiking, 170 kg of gear and 25 people in the team. We try to put some numbers on the experience we had during the Langtang, Nepal Himalaya expedition in November 2022. Behind the scenes Remote mountain fieldwork can be quite an ...[Read More]

After two years of great work, our current cryosphere division ECS representative TJ Young is passing on the task of representing the needs and wishes of the cryosphere division early career scientists (ECS). As they make up a majority of the EGU members, their representatives make sure to see their needs and voices heard. You might know that the EGU ECS community is represented by two union-level ...[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 is strange, so let us take a closer look at the mystery of the ice-cold rose. Where the Wild Roses Gr ...[Read More]

What not to miss at this year’s EGU General Assembly

We are already half way through April and that means that this year’s EGU General Assembly (GA) is just around the corner. Whether this will be your first, second or seventh EGU GA, you are probably still overwhelmed by the jungle of opportunities there are – courses, medal lectures, talks, discussions, poster sessions – no? We certainly still are and that’s why we always collect our f ...[Read More]
