What is the difference between ‘water withdrawal’ and ‘water consumption’, and why do we need to know?

Post by Inge de Graaf, University of Freiburg, Environmental Hydrological Systems group ________________________________________________________________________________________________________________ Last week I had to teach my first class in global hydrology. When I showed the global trend on increasing demands and withdrawals (see Figure) I needed to explain the different terms as sometimes the ...[Read More]

Image of the Week – Heat waves during Polar Night!

June 23, 2017

  The winter 2016-2017 has been one of the hottest on record in the Arctic. In our Image of the Week, you can see that air temperatures were positive in the middle of the winter! Let’s talk about the reasons and implications of this warm Arctic winter. But first, let’s take a tour in Svalbard, the gateway to the Arctic… A breach in the one of the world’s largest seed vaults The Global S ...[Read More]

GeoTalk: The life and death of an ocean – is the Atlantic Ocean on its way to closing?

Geotalk is a regular feature highlighting early career researchers and their work. Following the EGU General Assembly, we spoke to João Duarte, the winner of a 2017 Arne Richter Award for Outstanding Early Career Scientists.  João is a pioneer in his field. He has innovatively combined tectonic, marine geology and analogue modelling techniques to further our understanding of subduction initiation ...[Read More]

Light years from home – a geologist’s tale

In a departure from the usual posts we feature on the blog, today Conor Purcell (a freelance science writer) brings you a thought provoking science fiction piece. Grab a drink and dive into this geology inspired adventure! “It’s typical geology for a rocky planet” K reported. “Captured beneath the ocean at its northern pole, the core is a mix of metamorphic and sedimentary rock, with sand an ...[Read More]

Features from the field: Folding

Folding is one of the most common geologic phenomena in the world. I should start with defining the term ‘deformation’ in order to understand the folding process better. In geology, deformation is an alteration of the size or shape of rocks. Deformation is caused by stress, the scientific term for force applied to a certain area. Stresses on rocks can stem from various sources, such as ...[Read More]

How prehistoric water pit stops may have driven human evolution

Post by Matthew Robert Bennett, Bournemouth University and Mark O Cuthbert, Cardiff University Our ancient ancestors seem to have survived some pretty harsh arid spells in East Africa’s Rift Valley over five million years. Quite how they kept going has long been a mystery, given the lack of water to drink. Now, new research shows that they may have been able to survive on a small networks of sprin ...[Read More]

Image of the Week – When the dirty cryosphere destabilizes!

Ice is usually something you see covering large ocean areas, mountain tops and passes or as huge sheets in polar regions. This type of ice is clearly visible from space or with the naked eye. There is, however, a large volume of ice that is less visible. This ice is distributed over the polar and high alpine permafrost regions; and is the ice hidden below ground. It might be hidden, but that doesn ...[Read More]

The art of turning climate change science to a crochet blanket

We welcome a new guest post from Prof. Ellie Highwood on why she made a global warming blanket and how you could the same! What do you get when you cross crochet and climate science? A lot of attention on Twitter. At the weekend I like to crochet. Last weekend I finished my latest project and posted the picture on Twitter. And then had to turn the notifications off because it all went a bit noisy. ...[Read More]

Enmeshed in the gears of publishing – lessons from working as a young editor

Editors of scientific journals play an important role in the process research publication. They act as the midpoint between authors and reviewers, and set the direction of a given journal. However, for an early career scientist like me (I only defended my PhD in early December 2016) the intricacies of editorial work remained somewhat mysterious. Many academic journals tend to appoint established, ...[Read More]
