For some years now, Mary Schweitzer and her team have been researching the idea that organic molecules can be preserved for millions of years, specifically within dinosaurs. They have used a plethora of chemical and biotechnological techniques to demonstrate that, within animals like Tyrannosaurus rex, it is possible to find the residue of structures such …[Read More]

Fires in South East Asia
Smoke from a number of agricultural fires is currently blanketing Thailand and Cambodia. This is shown below in the satellite image from the MODIS instrument on the TERRA satellite. The red dots are classed as ‘thermal anomalies’ by the satellite instrument and are usually indicative of fires burning in these locations. The majority of the …[Read More]
Small volcanic eruptions and the global warming ‘pause’
A new paper in Nature Geoscience by Santer and colleagues revisits the volcanic scenarios used in modern climate model simulations. The authors consider the effects of including a ‘more realistic’ model for the influence of small volcanic eruptions on the climate system over the past two decades. Of course, more realistic means more difficult.. and one …[Read More]
Where did all the mammoths go?
Let’s go meta. Recently, ecologist extraordinaire Dr. Jacquelyn Gill (or is it Professor cos of that weird American system?) wrote a wonderful review article on the extinctions that affected many large mammal species during the last 50-10,000 years. This period is known as the Quaternary, and was a time when ice ages were running rife …[Read More]
Towards better quantifying human impacts: Looking back on the PAGES Workshop in Leuven
Firstly, I’d like to express my sincere thanks to Dr Jennifer Clear (Czech University of Life Sciences, Prague) for her input to this blog article. The first week of February saw dozens of scientists arrive at the Katholieke Universiteit Leuven for the PAGES Focus 4 Workshop. This event brought together geomorphologists, soil scientists, palaeoecologists, archaeologists …[Read More]
Imaggeo on Mondays: Friends in the field
Out in the field you encounter all sorts of wildlife and while mosquitos are the most frequent (and most unwelcome), they generally don’t interfere with your equipment or your data. The same can’t be said for all animals though, and many scientists have to strap their equipment out of reach, barricade it with barbed fences …[Read More]
Guest Blog: The Influence of Himalayan Geology
Amber Madden-Nadeau is studying Geology at Imperial College London. Amber recently wrote a report on the geology of the Himalayas, with a focus on the Ladakh region, as part of our hazards education project. Here, Amber summarises the important aspects of Himalayan geology and the influence they have on people’s lives. The Himalaya mountain …[Read More]
The Young Earth Scientists Network
Are you looking to join a global network of earth scientists? The Young Earth Scientists Network (YES Network) is an association of earth-scientists who are primarily under the age of 35 years that represent geological organisations and companies from across the world. The network has been established quite recently, in 2007, and has been running …[Read More]
Monday paper: Variability of above-ground litter inputs alters soil physicochemical and biological processes: a meta-analysis of litterfall-manipulation experiments
Xu, S., Liu, L. L., Sayer, E. J. 2013. Variability of above-ground litter inputs alters soil physicochemical and biological processes: a meta-analysis of litterfall-manipulation experiments. Biogeosciences 10, 7423-7433. DOI: 10.5194/bg-10-7423-2013 Abstract Global change has been shown to alter the amount of above-ground litter inputs to soil greatly, which could cause substantial cascading effects on below-ground biogeochemical cycling. Despite extensive study, …[Read More]
Counterintuitive solutions improve public transportation and urban design in Seattle
The Emerging Leaders in Environmental and Energy Policy (ELEEP) Network brings together young professionals from Europe and North America with the aim of fostering transatlantic relations. Former EGU Science Communications Fellow and ELEEP member Edvard Glücksman reports back from a study tour of the US Pacific Northwest. After describing urban planning strategies in Oregon in …[Read More]
