Ocean thermal expansion, that is, the increase in water volume due to temperature alone, is relatively well understood – as is the retreat of both mountain glaciers and ice caps. While most models simulate these effectively, there is little understanding of how both the Greenland and Antarctic ice sheets will respond to climate change. This is because the full extent of ice-ocean interactions is n ...[Read More]
Geosciences Column: The contribution of climate change to water scarcity in the MENA region
In this month’s Geoscience’s column, Alex Stubbings discusses the water scarcity problems in the Middle East and North Africa region and the recent developments in modelling water resources here. The Middle East and North Africa (MENA) region is considered the most water-scarce region in the world. As such, the region faces a multitude of challenges in the 21st century including population growt ...[Read More]
Imaggeo on Mondays: Storm in Mount Waddington
This week’s Imaggeo on Mondays is brought to you by the photographer herself, Marion Bisiaux (now at Stendhal University, Grenoble, France), who tells us about her exciting field trip to the British Columbia’s Coast Range. This picture was taken during the Waddington Range Ice Core Project in which I participated during my PhD at the University of Nevada, Reno, US and at the Desert Research Instit ...[Read More]
Imaggeo on Mondays: Melting ice
The speed and extent of Greenland’s ice sheet melt dominated the media over the summer, and for good reason. Dramatic satellite images showed that, in just a few days, 97% of the island’s ice sheet surface thawed, melting over a larger area than at any time in more than 30 years of satellite observations. Usually, during the summer only around half of the surface of Greenland’s ice sheet melts and ...[Read More]
