Did you know… about the fluctuating past of north-east Greenland?

Did you know… about the fluctuating past of north-east Greenland?

Recent geological data shows that during a very cold phase of our Earth’s climate (between 40,000 and 26,000 years ago), there was a huge expansion of polar ice sheets, yet the north-eastern part of the Greenland ice sheet was less extensive than today. How could this have occurred? In this post we shed light on the potential causes of this ice sheet behaviour. What do we know about present- ...[Read More]

Science as Type II Fun

Science as Type II Fun

Autumn had finally arrived – the weather had cooled down enough to start rock climbing outside again in southern Arizona. I was working on scaling a mountain’s cliff face tall enough to be a skyscraper with nearly 15 fellow scientists climbing routes around me. My palms were sweaty with nerves and my muscles were starting to get tired. I questioned what possessed me to climb this huge rock. ...[Read More]

Is the scientific community ready for open access publishing?

Is the scientific community ready for open access publishing?

How much we pay, as both scientists and the public, for publishing and accessing papers is a hot topic right across the academic community – and rightly so. Publishing houses, and their fees, are big, big business. To which journal we should submit our work is a regular decision we face. But what are the Green, Golden or Hybrid roads? How do pre- and post-prints fit into the journey? In this ...[Read More]

For Dummies – How do wildfires impact permafrost? [OR.. a story of ice and fire]

For Dummies – How do wildfires impact permafrost? [OR.. a story of ice and fire]

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 a pretty good understanding of how permafrost responds to fire t ...[Read More]

Ice-hot news: The IPCC Special Report on the Oceans and the Cryosphere under Climate Change

Ice-hot news: The IPCC Special Report on the Oceans and the Cryosphere under Climate Change

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 crisis and the need for more information by decision makers ...[Read More]

The conundrum posed by data and models

The conundrum posed by data and models

A privilege of being an academic is the freedom to muse, staying faithful to the title of a PhD which is, after all, a doctor of philosophy. In his latest reflection on a topic of importance to all scientific disciplines, Dan Bower (CSH and Ambizione Fellow at the University of Bern) discusses the ambiguity that comes with the separation of data and models.   What are data? What are models? You ar ...[Read More]

The bad, the good and the unpredictable: living with volcanoes / part 1

The bad, the good and the unpredictable: living with volcanoes     / part 1

Introduction Humans have existed and lived alongside volcanoes for as long as we have been on the planet. For some, this has been beneficial and often, in fact, we can see how indigenous knowledge finds a sustainable approach living with them. However, in some cases, societies cannot cope and are overwhelmed with volcanic eruptions.  There are many examples from archaeological studies dealing with ...[Read More]

Can limestone digestion by volcanoes contribute to higher atmospheric carbon dioxide levels?

Can limestone digestion by volcanoes contribute to higher atmospheric carbon dioxide levels?

By Frances Deegan and Ralf Halama Carbon – the element on everyone’s lips. Carbon is unquestionably one of the most important elements on Earth – terrestrial life is carbon-based and so are many of our energy sources. From the perspective of a human time-scale, biological and anthropogenic (caused by human activity) carbon fluxes are very important (e.g. through industrial activity and burni ...[Read More]
