For the Accretionary Wedge blog festival with the theme of ‘Momentous Discoveries in Geology’, Marion Ferrat discusses how a pioneering lady discovered what lies deepest inside our planet. We know a lot about our planet today: its position in the solar system, its age, its composition and its internal workings and structure. Many laborious experiments, …[Read More]

Momentous Discoveries in Geology – The World of Nano!
I first came across the intriguing world of nanoparticles when I saw an awe-inspiring talk by nano-extraordinaire Professor Michael Hochella from Virginia Tech at the Geological Society. He wove a fascinating tale about the world at nanoscale, the special properties, the infinite uses and the potential environmental impacts as well as outlining the need for caution, …[Read More]
Climate change: it’s just a matter of time!
Natural or man-made: what factors are responsible for the climate changes we are seeing today? Ahead of the release of the latest IPCC report next week, Marion Ferrat discusses the different factors affecting climate change and shows that who takes the blame all depends on timing… Over the past century, our planet’s climate system has …[Read More]
What’s all the Phos about?
Phosphate use for fertilisers, essential in modern agriculture, is hitting an all time high while resources are being heavily depleted. Flo discusses the background, numbers, geopolitics and potential solutions behind the issue of ‘the end of phosphorus’. The Issue The dilemma over diminishing natural resources is a topic of our times with the daily bulletins …[Read More]
What’s Geology got to do with it? 1 – The Maya civilisation
Geology is not just about looking at rocks. From finding oil and gas and tackling climate change to manufacturing, archaeology or geopolitics, geoscientists appear in most spheres of today’s world and economy, albeit often behind the scenes. In a new series of posts we will be looking at how geology relates to interdisciplinary or seemingly …[Read More]
Melting, microbes and methane: Are we about to face a carbon apocalypse?
Marion Ferrat takes a look under the frozen layers of Arctic permafrost and discusses how these soils may come back to haunt us. The vast plains of Siberian or Canadian permafrost are a sight to behold. Hundreds, sometimes thousands of miles of frozen soils cover these lands, a cold and barren environment. In places, however, …[Read More]
Murky waters – what counts as good water quality?
Flo Bullough discusses the meaning of good and bad water quality, what’s in our tap water and what policies control the content of drinking water. Pressure on water supply and quality has been high on the public and media agenda over the last 18 months. The widely publicised drought in early 2012, recent reports that …[Read More]
Four degrees: Discussions on climate change, policy, environmental geochemistry and sustainability
As we enter the 400ppm world for the first time in a good chunk of geological history, issues of environment, sustainability and climate change are, more than ever, a source of discussion – and often heated dispute – in the media. As these issues are debated by governments and policy-makers, hardly one day goes by without a series of …[Read More]
