By Brigid Fitzgerald / Earth Policy Institute first published May 12, 2011. As the world continues to add close to 80 million people each year, high population growth is running up against the limits of our finite planet, threatening global economic and political stability. To stay within the bounds of the earth’s natural resources, the…

NASA: The average temperature across the continental U.S. could be 8 degrees Fahrenheit warmer by the end of the 21st century under a climate scenario in which concentrations of the greenhouse gas carbon dioxide rise to 800 parts per million. Current concentrations stand at 400 parts per million, and are rising faster than at any…

Andrew Bliss, Regine Hock, J. Graham Cogley | Source Abstract Although the glaciers in the Antarctic periphery make up a large fraction of all mountain glaciers and ice caps on Earth, a detailed glacier inventory of the region is lacking. We compile such an inventory, recording areas, area–altitude distributions, terminus characteristics and volume estimates.Glaciers on…

By Bethan Davies / AntarcticGlaciers.org Introduction | Radio echo sounding | Satellite altimetry: elevation changes | Effects of active lakes on ice dynamics | Drilling projects | References Introduction The Antarctic continent is underlain by subglacial lakes. Despite the fact that they are overlain by several kilometres of ice, these lakes are interconnected and water…

By Bethan Davies / AntarcticGlaciers.org Introduction | Supraglacial hydrology | Englacial hydrology | Subglacial hydrology | Proglacial drainage | References Introduction Glacier hydrology is the study of the flow of water through glaciers. It is a mysterious world, where water running on the surface of the glacier disappears through cracks and holes in the glaciers,…

Published on YouTube Jul 25, 2013: World changing technology developed by experts at The University of Nottingham enables crops to take nitrogen from the air reducing the use of expensive and environmentally damaging fertilisers.
A collection of science around subglacial glacier’s, cavities and about water pressure/water flow. Though someone pointed out that most of the items are focused on land based glaciers, rather than on the WAIS which is a marine ice sheet. However, i welcome all contribution in the comment section which helps to better understand marine ice…

Via Robertscribbler: In a July 18 testimony to Congress, Dr. Jennifer Francis, an atmospheric scientist from Rutgers and key innovator to understanding how climate change has brought about dangerous alterations to the Northern Hemisphere Jet Stream, provides five compelling reasons why we should all be quite concerned about human caused global warming. They include: 1.…
