Bavaria glaciers could disappear in 30 years with warming rate double the global average

3 July 2012 (Spiegel) – The high-altitude landscape of the Bavarian Alps is prized by mountain sports lovers around the world, but it could change significantly in the coming years. Temperatures in the region are rising at an above-average rate, which will likely melt most of the glaciers there within the next 20 to 30 […]

Graph of the Day: Greenland Reflectivity Anomaly, June 2012

Satellite data of Greenland reflectivity 1-22 June 2012 versus the same periods in previous Junes back to 2000. The blue colors indicate a decrease in reflectivity compared to previous Junes. In a new study, Box and a team of researchers describe the decline in ice sheet reflectivity and the reasons behind it, noting that if […]

Greenland ice sheet melt nears critical tipping point ‘into a state of inevitable decline’

By Andrew Freedman29 June 2012 The Greenland ice sheet is poised for another record melt this year, and is approaching a “tipping point” into a new and more dangerous melt regime in which the summer melt area covers the entire land mass, according to new findings from polar researchers. The ice sheet is the focus […]

U.S. National Research Council predicts higher rates of sea level rise

22 June 2012 (AFP) – Global sea levels could rise two to three times higher over the next century than previous UN estimates, according to a study released Friday by the US National Research Council. A committee of experts evaluated the latest UN data and updated those projections with new data on polar ice-cap melting […]

Past periodic warmth in Arctic may be related to melting Antarctic ice sheets

Contact: Janet Lathrop, 413-545-044421 June 2012 AMHERST, Massachusetts – First analyses of the longest sediment core ever collected on land in the terrestrial Arctic, published this week in Science, provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million years. (“2.8 Million Years of Arctic Climate Change […]

The Economist: The melting north

By James Astill16 June 2012 STANDING ON THE Greenland ice cap, it is obvious why restless modern man so reveres wild places. Everywhere you look, ice draws the eye, squeezed and chiselled by a unique coincidence of forces. Gormenghastian ice ridges, silver and lapis blue, ice mounds and other frozen contortions are minutely observable in […]

Peru needs glacier loss monitoring: UN warning

By Roberto Cortijo 4 June 2012 Peru needs a permanent monitoring system to gauge Andean mountain glacier shrinkage caused by global warming and its effect on people who depend on the ice for water, UN experts warned. “We have spoken with Peruvian government institutions, and there is no sufficient monitoring system to tell us the […]

Fresh water demand driving sea-level rise faster than glacier melt

[But see What makes sea-level rise?] By Damian Carrington, www.guardian.co.uk 20 May 2012 Humanity’s unquenchable thirst for fresh water is driving up sea levels even faster than melting glaciers, according to new research. The massive impact of the global population’s growing need for water on rising sea levels is revealed in a comprehensive assessment of […]

Arctic melt releasing ancient methane – ‘The warming will feed the warming’

By Richard Black, Environment correspondent, BBC News20 May 2012 Scientists have identified thousands of sites in the Arctic where methane that has been stored for many millennia is bubbling into the atmosphere. The methane has been trapped by ice, but is able to escape as the ice melts. Writing in the journal Nature Geoscience, the […]

Another Antarctic ice shelf threatened by warming

By Chris Wickham; Editing by Janet Lawrence9 May 2012 LONDON (Reuters) – Scientists are predicting the disappearance of another vast ice shelf in Antarctica by the end of the century that will accelerate rising sea levels. The Filchner-Ronne Ice Shelf fringing the Weddell Sea on the eastern side of Antarctica has so far not seen […]
