You thought it was over? Here’s more on the 2023 Antarctic sea-ice extent record low

David Docquier and Bianca Mezzina April 26, 2024

A figure showing several lines for several years of sea ice extent. They look like a wave with the minimum around february each year and the maximum around october.

In November last year (see this post), we promised to provide you an update of what happened with Antarctic sea ice during the year 2023 – a year of an exceptionally low extent. In this post, we try our best to discuss the conditions that lead to (part of) the recent loss in Antarctic sea ice, including atmospheric and ocean processes. How sea ice usually works… One of the ways scientists h ...[Read More]

EGU24: The return of GeoCinema!

Hazel Gibson and Jane Roussak April 5, 2024

After a six year hiatus, GeoCinema is back for EGU24! As many of you know, doing science is very rarely just about the research, but also involves sharing that research in several forms and formats. For many talented researchers this means using films. Either working with a film-maker or creating something themselves, several of our EGU24 attendees submitted wonderful films this year, from science ...[Read More]

Equilibrium Crustal Thickness and Dynamics of Earth’s Lithosphere: The Answer is 42.

Ajay Kumar and edited by Lorenzo Mantiloni March 13, 2024

“The Hitchhiker’s Guide to the Galaxy” had the answer; we think we have the right question. This week, Ajay Kumar from IISER Pune, India, will take us on a journey to the depths of the Earth’s lithosphere – a world as mysterious as the farthest reaches of the Universe. We will see what the thickness of the Earth’s crust can tell us about the balance between the ...[Read More]

An end to the ‘manel’? 3 things you can do to help reduce the existence of all-male-panels.

Hazel Gibson March 8, 2024

I am pretty sure that everyone has had this experience at one time or another. You attend a meeting or conference and, despite the diversity of people in the audience, the people on the podium invited to speak are uniformly men. If you come from the same part of the world as I do (Western Europe) this experience can also probably be extended to the panel only being white, often native English spea ...[Read More]

Geotandem: The Red Planet, often recognized as a dead planet, is not quite dead after all, at least geodynamically speaking

Scott King, Joshua Murphy and edited by Constanza Rodriguez Piceda February 21, 2024

Welcome to the first of its kind, the Geotandem 01! A collaborative series between EGU divisions. Interdisciplinarity is intrinsic to Geosciences, so we want to showcase how researchers approach the same topics from different but also complementing perspectives. In each edition, we will bring you a high-interest topic for the community seen from the eyes of diverse disciplines. Today, the Tectonic ...[Read More]

Did you know that a lack of Arctic shipping regulation has detrimental environmental effects?

A. Stella Ebbersmeyer February 20, 2024

Increased maritime transport in the Arctic, facilitated by the reduction in sea ice cover, is causing tremendous harm to an already vulnerable part of the world. Insufficient regulation of Arctic shipping has detrimental environmental effects on a global scale. These effects include, e.g. underwater noise pollution, oil spill risk and threats to the global climate. But did you know what role regul ...[Read More]

Environmental (non-)migration: Whose security is at stake?

Soheil Mohammadi January 15, 2024

Migration is commonly perceived as a strategic response to address the repercussions of environmental threats and climate change. The International Organization for Migration defines ‘environmental migrants’ as those individuals who alter their place of residence due to a sudden or progressive change in the environment that adversely affects their lives or living conditions. Conversely, those who ...[Read More]
