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]

Cryo-adventures – Behind the scenes of cryo-fieldwork

As the Arctic is warming faster than the global average, Arctic glaciers are rapidly melting. My research is about the fate of glacial organic carbon when the ice containing it melts. To investigate these processes, I travelled to several glaciers, an activity full of challenges… and rewards! My research Glacier ice covers about 11% of Earth’s land surface, and contains within it a globally ...[Read More]

Geothermal Energy and Structural Geology?

Geothermal Energy and Structural Geology?

Fieldwork is a necessity to expand the brain, to kick-start 3D thinking. Field studies with a specific application in mind have – until now – usually been geared towards hydrocarbon reservoirs. However, with the increasing use of the subsurface, for example for CO2 storage and geothermal energy, alternative field studies gain importance. Here, we will focus on geothermal energy, which is in ...[Read More]

Geosciences Column: Taking a Breath of the Wild – are geoscientists more effective than non-geoscientists in determining whether video game world landscapes are realistic?

Geosciences Column: Taking a Breath of the Wild – are geoscientists more effective than non-geoscientists in determining whether video game world landscapes are realistic?

For years, geoscientists have been both fascinated and perplexed by the beautiful (yet often inaccurate) landscapes present in several video games. But are people with a geoscientific education better at telling ‘fake’ natural features from real ones? Rolf Hut, an assistant professor at Delft University of Technology in the Netherlands, and his colleagues sought to answer this question in a new st ...[Read More]

Featured catchment series: Disentangling the ecohydrology of a tropical hotspot!

Zhurucay Ecohydrological Observatory: Critical zone observations at the top of the Andes! A natural laboratory of tropical alpine ecohydrology Tropical alpine ecosystems, known as the Páramo, extend to high elevations (3,000-5,000 m a.s.l.) mainly through the northern Andes of South America from Venezuela to northern Peru. Given their geographical location and elevation, Páramo areas are exposed t ...[Read More]
