In a recent paper, Temme (2015) has used descriptions of rockfall risk in Alpine climbing guides to examine the effects of climate change on the degradation of permafrost and the resulting increased occurrence of

From the ever eloquent Today In Science History: Wright (Dec. 21, 1889 – March 3, 1988) was an American geneticist who was one of the founders of modern theoretical population genetics. He researched the effects of inbreeding and crossbreeding with guinea pigs, and later on the effects of gene action on inherited characteristics. He adopted statistical techniques to develop evolutionary

Imaggeo on Mondays: Science in action – how will climate change affect Central Europe?

 DE,CN,
The effects of a warming climate are expected to be far reaching. Sea-level rise, and how it will affect costal settlements make regular headlines, and not without reason. However, climate change may have other less obvious but equally dangerous impacts; for example, take a look at this recent piece highlighting the increased risk of storms and droughts in mainland Europe. The area of Saxony-Anhalt, in northern Germany, has a rich cultural, historical and natural heritage, which is coming under [...]

Today's new ELI is 'Question you can ask at any rock face 2: erosion'. Erosion is ‘The removal of solid material, by gravity, water, wind or ice’ and so is the beginning of transportation. Take your pupils to an area of loose rock beneath a rock face, preferably with water-formed gullies leading away – and ask the questions listed in the activity. The effects of erosion by gravity are

We are currently mapping our last survey line on Tamu Massif, and we will soon be ready to head out. The planetary Kp index, used to characterize the magnitude of geomagnetic storms, says the magnetic field is a little unsettled. Although we cannot do much about this and we will not know the effects of this magnetic storm on our data, we will acquire the Kakioka (Japanese) magnetic observatory records after the cruise to determine a baseline of what we should have been collecting. The exiting [...]

The Athabasca Glacier is located in Jasper National Park, in the Canadian Rockies. It is the largest of seven named distributary glaciers carrying ice away from the Columbia Icefield, the largest icefield in the Rocky Mountains. This picture shows a summer meltwater stream running on the surface of the ice disappear in a moulin – a vertical shaft forming part of the glacier’s internal plumbing system. After entering the moulin, the meltwater may flow through englacial streams before [...]

M4.0, recorded as an M4.6 in the directivity zone. You can see it's a shallow strike-slip with a bit of thrust to get that high intensity.  Lo and behold, that's what it is. This is right at the end of the big shear zone, so I'm guessing that the thrust aspect is mainly due to end effects. There's not much activity elsewhere, so there is a chance that all the hard points have

Iceland has a complicated relationship with climate change. As in much of the far north, global warming is already exerting many effects here–arguably both good and bad. Yet the country contributes relatively little to the warming, since most of its energy comes from geothermal and hydro plants, which produce little carbon dioxide. Now, it is

 CN,IE,GB,
During ice ages landscapes are sculpted by the power of advancing glaciers. From rock scratches, to changing mountains and the formation of corries, cirques and aretes, through to the formation of valleys and fjords, the effects of past glaciations are evident across the northern hemisphere landscape. Perhaps not so familiar, drumlin fields are also vestiges of the erosive power of ancient ice sheets. Glacial deposits tend to be angular and poorly sorted, meaning they come in lots of different [...]

The bottom of Death Valley is the driest place in North America, and the hottest place in the world. It might stand to reason that it is a place that withstands the effects of California's horrific four-year drought, which is true, but it's not necessary this year. Death Valley is one of the few parts of the state that is running close to normal in the precipitation department. Source:
