Extensive ice in Antarctica

Released by National Snow and Ice Data Center | Access date January 4, 2013. While it is early winter in the Arctic, it is early summer in the Antarctic. Continuing patterns seen in recent years, Antarctic sea ice extent remains unusually high, near or above previous daily maximum values for each day in November. Sea ice…

Why is Antarctic sea ice growing?

Published on Nov 8, 2012: Suggestions that modest increases in sea ice around Antarctica offset significant losses in Arctic sea ice are based on a bogus “apples and oranges” comparison. Through interviews with a range of respected experts, Peter Sinclair’s newest Yale Forum video explains why such suggestions do not stand up to scientific scrutiny. Related…

Chris Hayes & Michael E Mann: There’s Global Warming – And It’s Snowing

Chris Hayes from MSNBC talks to Michael E Mann about global warming deniers and the season we call “winter.” Release with full segment URL Chris Mooney in MotherJones: 1. Statements about climate trends must be based on, er, trends. Not individual events or occurrences. Weather is not climate, and anecdotes are not statistics. 2. Global warming is actually…

Abrupt Climate Change In The Arctic (And Beyond) An Update

AGU Fall Meeting 2013: Our understanding of future Arctic change is informed by the history of past changes, which often have been both large and abrupt. The well-known ice-age events such as the Younger Dryas show how sea-ice changes can amplify forcing to produce very large responses, with wintertime sea ice especially important. These changes…

Rebound an Earth Story


Glacial isostatic adjustment, why we have glacial and interglacial periods, how we can reconstruct climate history, and how the Earth is responding to the retreat of the continental glaciers.

Singapore sized iceberg breaks off in Antarctica

Pine Island Glacier 2013, Nov. 10: This MODIS image taken by NASA’s Aqua satellite on Nov. 10, 2013, shows an iceberg that was part of the Pine Island Glacier and is now separating from the Antarctica continent. What appears to be a connection point on the top left portion of the iceberg is actually ice…

Sea level rise: New iceberg theory points to areas at risk of rapid disintegration

Video published on YouTube Nov 21, 2012 | Article published on July 22, 2013 by Nicole Casal Moore / University of Michigan ANN ARBOR—In events that could exacerbate sea level rise over the coming decades, stretches of ice on the coasts of Antarctica and Greenland are at risk of rapidly cracking apart and falling into…

Remote Antarctic Trek Reveals A Glacier Melting From Below

September 15, 2013 by Richard Harris from NPR – Scientists watching Antarctica’s Pine Island Glacier from space have noticed with some alarm that it has been surging toward the sea. If it were to melt entirely, global sea levels would rise by several feet. Source NPR (with transcript) Related New Antarctic ice core reveals secrets…

Life found in the sediments of an Antarctic subglacial lake for the first time

Video: What Lies Beneath: NASA Antarctic Sub Goes Subglacial NASA / JPL February 28, 2013: When researcher Alberto Behar from NASA’s Jet Propulsion Laboratory in Pasadena, Calif., joined an international Antarctic expedition last month on a trek to investigate a subglacial lake, he brought with him a unique instrument designed and funded by NASA to help…

NASA Operation IceBridge: Stunning Aircraft Travel – Documenting Antarctic and Greenland Change

Published on YouTube Aug 16, 2013: The views from the cockpit of NASA’s P-3B aircraft on an Operation IceBridge campaign are truly stunning. The mission doesn’t travel to both ends of the Earth for the scenery of course — the airborne mission is there to collect radar, laser altimetry, and other data on the changing…

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…

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…
