Imaggeo on Mondays: The warming

Imaggeo on Mondays: The warming

Events of meteorological significance, such as thunderstorms, hurricanes, cyclones, jet streams and global-scale circulations can be described by a general term: atmospheric dynamics. When it comes to it, atmospheric dynamics deals with nothing more than air, which, in truth, is very difficult to directly observe, (with the exception of clouds and precipitation). This makes the study of atmospheri ...[Read More]

Imaggeo on Mondays: Mountains, rivers and agriculture

This week’s Imaggeo on Mondays image blends a range of geoscience disciplines. The post, by Irene Marzolff, a researcher at Johann Wolfgang Goethe-Universitaet, explores how the mountains, rivers and soils of the High Atlas in Morocco are intrinsically linked to the agriculture of the region. The image was taken in the southern slopes of the Western High Atlas, north of the city of Taroudann ...[Read More]

GeoTalk: Deciphering the mysteries of the Mediterranean Sea with Katrin Schroeder

GeoTalk: Deciphering the mysteries of the Mediterranean Sea with Katrin Schroeder

Geotalk is a regular feature highlighting early career researchers and their work. Following the EGU General Assembly, we spoke to Katrin Schroeder, the winner of a 2015 Arne Richter Award for Outstanding Young Scientists. First, could you introduce yourself and tell us a little more about your career path so far I am a physical oceanographer with a background in environmental science. I did my st ...[Read More]

Geosciences Column: When water is scarce, understanding how we can save it is important

Geosciences Column: When water is scarce, understanding how we can save it is important

Supplies of water on Earth are running dry. The rate at which an ever growing population consumes this precious resource is not matched by our Planet’s ability to replenish it. Water scarcity is proving a problem globally, with regions such as California and Brazil facing some of the most severe water shortages on record. Used for drinking, agriculture and industrial processes, water forms an fund ...[Read More]

Imaggeo on Mondays: Late Holocene Fever

Imaggeo on Mondays: Late Holocene Fever

A huge ice fall off the Perito Moreno glacier in the Los Glaciares National Park, southwest Santa Cruz Province, Argentina, was voted one of the three best pictures entered into the EGU’s annual photo contest, by the conference participants at the 2015 General Assembly. Perito Moreno glacier is one of 48 glaciers feeding into the Southern Patagonia ice field, which combined with the Northern Patag ...[Read More]

Film review: Revolution

Film review: Revolution

It’s not every day you are asked to review a film, and since it’s a documentary that encompasses a few of EGU’s sciences (such as climate sciences, biogeosciences, and energy, resources and the environment), I couldn’t say no. I’ll start by giving it a rating, 3.5/5 stars, though I would probably give it more if I were part of the film’s main target audience. Revolution, by biologist-photographer ...[Read More]

Imaggeo on Mondays: Just Passing

Imaggeo on Mondays: Just Passing

If lucky enough to visit Ilulissat Icefjord, you’d find yourself in a truly ancient landscape. From the up to 3.9 billion year old Precambrian rocks, to ice dating back to the Quaternary Ice Age (2.6 thousand years old) and archaeological remains which evidence the past settlement of this remote Greenlandic outpost, it’s no surprise this stunning location has been declared a UNESCO world heritage ...[Read More]

Geosciences Column: Recent and future changes in the Greenland Ice Sheet

Geosciences Column: Recent and future changes in the Greenland Ice Sheet

Over the past few decades, the Arctic region has warmed more than any other on Earth. The Greenland Ice Sheet is losing mass faster than ever before, and is expected to keep melting with consequences for global sea-level rise and ocean circulation. At a media briefing, during the EGU’s General Assembly in April (stream it here), researchers presented new results on the factors that influence the G ...[Read More]

Imaggeo on Mondays: Foehn clouds

This week’s post is brought to you by Stefan Winkler, a Senior Lecturer in Quaternary Geology & Palaeoclimatology, who explains how the mountain tops of the Southern Alps become decorated by beautiful blanket-like cloud formations. The Sothern Alps of New Zealand are a geoscientifically dynamic environment in all aspects. They are arguably one of the youngest high mountain ranges in the ...[Read More]

Floods and droughts set to increase due to climate change

Floods and droughts set to increase due to climate change

The planet is set to encounter a record-level amount of floods and droughts by 2050 – researchers recently announced at the European Geosciences Union’s General Assembly in Vienna. Nikita Marwaha shares their predictions on the impact that climate change will have on these extreme weather conditions. In a study by the Joint Research Centre (JRS) – the European Commission’s in-house science service ...[Read More]
