Each day, several tens of tiny earthquakes happen beneath Rutford Ice Stream in Antarctica. These events are so small that no human would be able to feel them – yet, scientists can use recordings of these so-called “icequakes” to obtain valuable information on the way ice flows in Antarctica. Read on to find out how… …[Read More]
Climate models help us understand processes occurring in and between atmosphere, oceans, land and ice-covered regions of our planet. One important process impacting all of us is sea level rise, and the ice sheets of Antarctica and Greenland (currently losing more and more ice) play a crucial role in future sea level rise projections. Even …[Read More]
When most people hear the phrase “radiocarbon dating”, they think of measuring carbon to date organic material. But did you know that carbon is also produced within rocks, and that we can use it to learn about the past behaviour of a glacier? About 20,000 years ago it was colder and large parts of the …[Read More]
Beneath the frozen surface of the Southern Ocean, live some of the most spectacular creatures on earth. These creatures are spectacular not only in appearance, but also in their ability to survive in such an extreme environment as Antarctica. Here, temperatures deviate only slightly from 0°C, and food is scarce during the winter months. How …[Read More]
7 meters of sea-level rise – what you would get if the whole Greenland Ice Sheet melted. But the tricky question is: how much of this ice will be melted in the next decades, and how fast will it occur? This piece of information is critical in order to plan for present and future populations …[Read More]
![For Dummies – How do wildfires impact permafrost? [OR.. a story of ice and fire]](https://blogs.egu.eu/divisions/cr/wp-content/uploads/sites/17/2019/10/DJI01011-1024x768.webp)
Wildfire – like the ones observed in the Northwest Territories, Canada in 2014 (Fig. 1) – is a natural part of permafrost landscapes, but fires are expected to get more frequent and severe as the climate warms. This could accelerate the degradation of permafrost, with negative consequences on the local and global scale! We have …[Read More]
You have probably heard the name “Intergovernmental Panel on Climate Change (IPCC)” mentioned frequently over the last few years. The IPCC is the United Nations body for assessing science related to climate change and it publishes global assessment reports on this topic every 5 to 10 years. Due to the current urgency of the global climate …[Read More]
In this week’s blogpost, author, editor, artist, and outreach expert Marlo Garnsworthy gives some insights into her recent trip to Iceberg Alley, gives you some tips on how to communicate icy science, and shows us her inspirational artwork. If you’re reading this, ice may be on your mind. Ice is surely on mine. During my …[Read More]
How do you get there? Where will you sleep? What work will you do there?These are just a few of the many questions I got from family and friends when I told them that I would join the EastGRIP ice core project this summer. As a paleo climate and ice sheet modeller, I could only …[Read More]
The GROCE project, funded by the German Ministry for Education and Research (BMBF), takes an Earth-System approach to understand what processes are at play for the 79°N glacier (also known as Nioghalvfjerdsfjorden), in northeast Greenland. 79°N is a marine-terminating glacier, meaning it has a floating ice tongue (like an ice shelf) and feeds into the …[Read More]
