The Global Arctic, a personal perspective on interdisciplinary research

The Global Arctic, a personal perspective on interdisciplinary research

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 better understanding of the significance of the concept of Gl ...[Read More]

Did you know the differences between Arctic and Antarctic sea ice?

Did you know the differences between Arctic and Antarctic sea ice?

If you look at the maps in Figure 1, you will quickly see that sea ice is present in both polar regions (Arctic at the top, Antarctic at the bottom). Despite this apparent similarity, some differences exist between Arctic (in the Northern Hemisphere) and Antarctic (in the Southern Hemisphere) sea ice. We provide a brief explanation of two key differences in this post. Geography The first main diff ...[Read More]

Winds and Antarctic sea-ice cover: what is the role of human activities?

Winds and Antarctic sea-ice cover: what is the role of human activities?

We may not often think about it, but climate in Antarctica can be very different depending on where we are exactly (do not expect palm trees though!). Winds play a big role in shaping these differences, which are reflected – among other things! – on sea ice. But how are these winds related to the large-scale atmospheric circulation, and are we having an impact on them? Dear readers, pl ...[Read More]

Why the 2022 Italian snow drought matters to you

Why the 2022 Italian snow drought matters to you

June 2022: I was discussing the ongoing drought with my family over lunch, when my dad pointed to me and summarized things as follows: “You know, less snow in winter means less water in summer!” I almost choked … what? Not only was it the first time I realized my family had been listening to my scientific anecdotes for years, but I also had concrete evidence now that snow was entering public ...[Read More]

Summer 2022: A perfect storm for Alpine glaciers

Summer 2022: A perfect storm for Alpine glaciers

The summer of 2022 is shaping up to be a perfect storm for Alpine glaciers. By a strange coincidence, all the factors that could adversely affect glacial dynamics seem to have come into agreement. Let’s find out why. What controls the behavior of Alpine glaciers? Snow, temperature, weather conditions and the properties of snow and ice. These are the most important factors governing the life ...[Read More]

Ice-hot news: A cryo-summary of the new IPCC assessment report!

Ice-hot news: A cryo-summary of the new IPCC assessment report!

We have waited eight years for it, and it is finally out: the 6th Assessment Report of the Intergovernmental Panel on Climate Change (a.k.a. « IPCC AR6 »)! And it is more than 10,000 pages long across Working Groups! Fortunately, a synthesis report integrating the findings of all three working groups should be released in Autumn 2022. However, we, at the EGU Cryosphere Blog, thought it might be us ...[Read More]

Current challenges: high-altitude Chilean glacier monitoring in an extended drought

Current challenges: high-altitude Chilean glacier monitoring in an extended drought

Central Chile has been facing a long dry period since 2010, marked by a high mean precipitation deficit, a so-called Mega Drought (MD) (Garreaud et al., 2019). This, besides long-term temperature increase (Burger et al., 2018; Falvey & Garreaud, 2009), has affected negatively the glaciers’ mass balance in the region mainly due to low snow accumulation throughout a hydrological year (which is f ...[Read More]

More pancakes in the future!

More pancakes in the future!

More pancakes in the future – that sounds like a very good New Year’s Eve resolution for Sunday brunches, but it could also be a development of the most tasty looking sea ice shape in the Arctic. Let’s find out more! Arctic Sea Ice The growth and melt of Arctic sea ice follows a seasonal cycle. In the springtime, under the midnight sun, the sea ice begins to melt until it reaches its m ...[Read More]

You left us too early: a eulogy to permafrost

You left us too early: a eulogy to permafrost

Most problems faced in research are complex and require creativity and critical thinking. Thus, we need to be creative in science! Or maybe, science itself is creative and there is no such thing as non-creative science. Anyhow, in today’s world, where TED-talks, science slams and elevator pitches, not to mention tweets, are ubiquitous, it is important that scientific expression takes on a form tha ...[Read More]

Time & space of glaciers

Time & space of glaciers

People usually perceive space and time, comparing them to their own life Words such as “forever” and “until the end” appear in fiction But how can we imagine the space and time of the mountain glaciers whose existence goes beyond our usual perception? And why is it so important for us now? With this post, researcher Alexandra Rogozhina shares her thoughts on these suggestive topics. Mostly, ...[Read More]
