Climate change stokes violent reaction

By Tim Radford / Climate News Network An exhaustive study of a wide range of conflicts over thousands of years has found that rising temperatures are inevitably linked to an increase in violence. LONDON, 1 August – Stand by for more violence. As planetary temperatures rise, so does the likelihood of murder, rape and domestic…

Glaciers and Global Warming

Published on YouTube Nov 21, 2012: Ice shelves that have lived for more than 10,000 years are disintegrating rapidly — in 6 weeks or less. U-M professor Jeremy Bassis is exploring how global warming is effecting glacial calving, and what impact these events will have on the rise of sea level. Related Greenland And Antarctica…

Greenland Ice Sheet: “Starting to Slip”

Published on YouTube Jul 29, 2013: Research scientists provide insights on recent ‘unprecedented’ melting of Greenland’s interior ice sheet. Latest video for The Yale Forum on Climate Change & the Media, the first since returning from Greenland – includes interviews with Ice expert Alun Hubbard, who I met in Kangerlussuaq, as well as a snip from…

Population: Education Leads to Lower Fertility and Increased Prosperity

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: Projected U.S. Temperature Changes by 2100

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…

A new inventory of mountain glaciers and ice caps for the Antarctic periphery

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…

Subglacial Lakes

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…

Glacier hydrology an introduction

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,…

A closer look at subglacial glacier cavities and water pressure

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…

Why Global Warming Should Keep You Awake at Night: Dr. Jennifer Francis Gives Chilling Testimony to Congress

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.…

Under the Ice: A closer look at recent Antarctica and Greenland Ice Melt
