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…

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…

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…

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

Source: Polar science news in brief “Environ Earth Sci (2013) 68:1813–1821 DOI 10.1007/s12665-012-2185-y by David Carlson Summary Antarctica Satellite radar altimetry since 2002 shows accelerated thinning (Amundsen Sea, Pine Island and Thwaites glacial ice streams) Laser altimetry shows thinning on 20 of 54 Antarctic ice shelves Ice shelves buttress their tributary glaciers, melt-induced thinning of…

Stable Antarctic Permafrost Melting Faster than Expected

University of Texas: July 24, 2013 AUSTIN, Texas — For the first time, scientists have documented an acceleration in the melt rate of permafrost, or ground ice, in a section of Antarctica where the ice had been considered stable. The melt rates are comparable with the Arctic, where accelerated melting of permafrost has become a…

Does Sea Ice loss create the condition for an emerging permanent El Nino state?

Recently Doug asked: “…my question is, how far could this phenomenon go? What is the “end” state? Is it possible for example that we could find the jet stream staying in place for months at a time, years, decades? How wavy could this waviness become?” A main theme of Sea ice loss seems to be…

Melting Sea Ice in the Arctic

Five Myths About Arctic Sea Ice http://sites.agu.org/sharingscience/f… Changes in Arctic sea ice coverage are happening at unprecedented rates, with 2012 setting a new record low for sea ice extent. Our ability to predict changes of sea ice loss and understand the impacts on society, from commercial shipping to resource availability, will be driven by further…
