Greenland ice sheet collapse, triggered ancient sea level rise 400,000 years ago

New evidence suggest that the longest interglacial (the time in between ice ages) – a warming period, called Marine Isotope Stage 11, more than 400,000 years ago, created nearly complete deglaciation of southern Greenland, thus contributed 4-6 meters to global sea level rise at that period. Overall se alevel rose about 6-13 meters above present…

Permafrost and the mysterious Crater/Sinkhole (Jamal, Siberia)

Evidence indicates that the Jamal sink hole (Siberia) has been caused by permafrost thaw, still under investigation. New footage (July, 18 2014) shows the crater in more detail, and Dan Miller explains the interconnections of climate change and permafrost. Anna Kurchatova: Siberia’s frozen soil — known as permafrost — contains millions of tons of methane…

Super Typhoon Rammasun makes landfall in China (Update)

Video, David McKenzie (CNN) describes China’s preparations to deal with the enormous Typhoon Rammasun, and considered the strongest typhoon in 40 years, to target China. Jeff Masters: Deadly Typhoon Rammasun is located about 440NM NW of Manila heading towards the South China Island of Hainan (population of 9 million). Latest satellite imagery estimates indicate the…

Record floods, submerged Fenghuang ancient town, Hunan province – July 2014

Severer storms caused record floods in the ancient Chinese town of Fenghuang (Hunan province),  Guizhou province and Jiangxi province. Today (Saturday 18th, July 2014) Rammasun, a super typhoon is approaching the China coast, considered the strongest storm to target China in 40 years. The Telegraph: According to China’s official Xinhua news agency, the Tuojiang river in…

Methane explosion investigated as cause for mysterious Siberian sink hole (Update)

Salon: According to Anna Kurchatova, with the Sub-Arctic Scientific Research Centre, the hole could have to do with the thawing of Siberia’s permafrost, a consequence of global warming. The rapid release of gas previously trapped in the ice, she said, could have combined with sand beneath the surface to form an underground explosion. The Siberian…

Ice cores what they reveal and how deniers distort the data

First posted in 2011, still popular on denialist blogs. Peter Sinclair explains:  A widely circulated piece of climate denial nonsense purports to use legitimate evidence from Greenland ice cores to debunk the record of global warming. Displaying temperature records out of context, and making the claim of legitimacy by citing the data, and it’s primary author,…

Why is Antarctic sea ice expanding?

By Laura Naranjo (NSIDC), first published January 31, 2014. In the following  an edited version, reposted here with permission. Antarctic sea ice is ruled by very different systems than Arctic sea ice. The reasons behind this increase are complex, and several recent studies show that scientists are still trying to understand them. Ice and wind Atmospheric…

New mechanism uncovered, causing potentially rapid Antarctic Glacier melt

An Australian-led research team found that sea levels may rise much faster than previously predicted by models, because changes by disruptive westerly winds, weren’t taken into account. Conservative estimates so far, projected irreversible melting in the course of a few centuries, depending on the temperature increase. Related Each degree of global warming might ultimately raise…

The Runaway Glaciers in West Antarctica

NASA/JPL press release, May 12, 2014: A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea. The study presents…
