How over-consumption leads to reduced sea ice: Visualization through artwork

How over-consumption leads to reduced sea ice: Visualization through artwork

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.

Highlighted Paper – Human Errors in Snow Models

Highlighted Paper – Human Errors in Snow Models

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]

Quantifying the experience: Himalayan fieldwork in numbers

Quantifying the experience: Himalayan fieldwork in numbers

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]

The more the merrier – Interview with the two new Cryo ECS representatives

A women on the left in front of a glacier face and a women on the right on front of a city landscape.

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]

Did you know the mystery of the ice-cold rose?

Did you know the mystery of the ice-cold rose?

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

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]

Did you know that cracks play a large role in the Arctic sea ice production?

Did you know that cracks play a large role in the Arctic sea ice production?

What do you need to form sea ice? Well, you can start with some sea water, an ocean will do, and cold air above it. Once a layer of ice starts forming, break it to make some cracks. You would have not thought of that? Yet, our recent study suggests cracks in the ice contribute significantly to Arctic winter sea ice production. A relationship between sea ice formation and breakup? We have known for ...[Read More]

Highlighted Paper – The ice factories of the Arctic Ocean

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 also freeze less, but we have observed that the ice growth – or ice production – has increased ...[Read More]
