How climate change can possibly increase the intensity of tornadoes in Europe

How climate change can possibly increase the intensity of tornadoes in Europe

On October 23 2022, a tornado outbreak occurred in France, causing extensive damages. Tornadoes in France are a relatively rare phenomenon, even more so in the second half of October. This weather phenomenon is linked to intense thunderstorms, and it is difficult to predict because it is very localized. Will global warming make this weather more frequent or intense? A thundercloud that grows visib ...[Read More]

The sedaDNA scientific society, a collaborative network of international researchers working with sedimentary ancient DNA

October 26, 2022
A group of people working together on laptops around a table in a room.

Emergence of the field of molecular paleoecology Sequencing DNA of organisms that died a long time ago sounds like the synopsis of the movie Jurassic Park (1993). Let’s make it clear right now, dinosaur DNA has never been collected by humans. To date, the oldest DNA recovered is more than one million years old and comes from mammoths. In addition to the DNA recovered from fossils, aquatic and terr ...[Read More]

Unravelling the geological past of the Sierra del Nevado, in South Andes, Argentina

Have you ever wondered to learn more about the geological setting of the Nevado volcano in Central-West Argentina? In this week’s blog, we have Georgina Rubiano Lorenzoni, a Ph.D. Geologist student from the Universidad Nacional de La Pampa in Argentina, who will guide us through her thesis aims, which are the identification and investigation of the petrogenesis and geochronology of the mountain ra ...[Read More]

Let’s begin the recovery before the disaster

Let’s begin the recovery before the disaster

Every natural event that causes damage to the built environment must be followed by recovery; however, this phase of disaster risk management has received less attention from academics than the others [1]. In all its aspects, disaster recovery has remained a contentious topic, with experts debating its definition, approaches, objectives, activities, and even when it should begin and finish [2–4]. ...[Read More]

International Continental Scientific Drilling Program Workshops – How they work and why they provide fascinating experiences and perspectives, especially for early career scientists

Thanks to the novelty and potential of my research focus (a paleothermometer for lacustrine environments based on the application of the carbonate clumped isotope technique on small crustacea shells (ostracods)) that provides insights into atmospheric temperatures of the past, I was selected by the committees of three International Continental Scientific Drilling Program (ICDP) workshops. The aim ...[Read More]

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]

Fagradalsfjall 2021 versus 2022: similarity and differences

The Icelandic eruptions of 2021 and 2022 originated in the Reykjanes peninsula, characterized by the Krýsuvík-Trölladyngja system, one of the five volcanic systems present along the peninsula. This peninsula is a leaky transform fault, characterized by episodic rifts and associated volcanism. The last two years have brought about some of the most momentous volcanic eruptions in recent history. The ...[Read More]

Earth Science Beyond Academia

Although a career in academic research is a great choice for some, the majority of PhD students will pursue careers outside of universities and research institutes. This week, we learn about the experiences of PhD and Masters students who are embarking on successful careers beyond academia.   Name: Deborah Wehner Degree: PhD in Earth Sciences New field: Tech Current Role: Software Developer E ...[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]

The Sassy Scientist – Unbelievable Lunacies

Being the reasonable, far-sighted and moderate entity that it is, humanity is irreversibly destroying the habitability of the planet it was given. I hope (man, I *hope*) I don’t have to convince anybody about this *fact*. Most of us are not concerned about this. Some of us are a tad concerned about the fact that the  IPCC has declared that keeping the excess temperature below 1.5 degrees has ...[Read More]
