New study of natural CO2 reservoirs: Carbon dioxide emissions can be safely buried underground for climate change mitigation

New study of natural CO2 reservoirs: Carbon dioxide emissions can be safely buried underground for climate change mitigation

New research shows that natural accumulations of carbon dioxide (CO2) that have been trapped underground for around 100,000 years have not significantly corroded the rocks above, suggesting that storing CO2 in reservoirs deep underground is much safer and more predictable over long periods of time than previously thought, explains Suzanne Hangx a postdoctoral researcher at the University of Utrech ...[Read More]

Fieldwork at 5,000 meters in altitude

Imja Lake is one of the largest glacial lakes in the Nepal Himalaya and has received a great deal of attention in the last couple decades due to the potential for a glacial lake outburst flood. In response to these concerns, the UNDP has funded a project that is currently lowering the level of the lake by 3 m to reduce the flood hazard. The aim of our research efforts is to understand how quickly ...[Read More]

Imaggeo on Mondays: Rock glaciers

Imaggeo on Mondays: Rock glaciers

Picture a glacier and you probably imagine a vast, dense mass of slow moving ice; the likes of which you’d expect to see atop the planet’s high peaks and at high latitudes. Now, what if not all glaciers look like that? Take some ice, mix in some rock, snow and maybe a little mud and the result is a rock glacier. Unlike ice glaciers (the ones we are most familiar with), rock glaciers have very litt ...[Read More]

Monday paper: The challenge and future of rocky desertification control in karst areas in southwest China

Zhang, J. Y., Dai, M. H., Wang, L. C., Zeng, C. F., and Su, W. C. 2016. The challenge and future of rocky desertification control in karst areas in southwest China. Solid Earth, 7:83-91, DOI:10.5194/se-7-83-2016, 2016.   Karst ecosystems in China are one of the main objectives of desertification control, since its conservation is important for economic and social development, especially of th ...[Read More]

The smallest volcanic island in the world?

The smallest volcanic island in the world?

One of the delights of talking to children of primary school age is their disarming ability to ask really simple questions that demand straightforward answers, but leave you struggling to throw your academic caution to the wind. Even with the questions of the biggest, the smallest, the oldest and the youngest there are still different ways of (over)interpreting the question, that can leave you flo ...[Read More]
