Sudden ice loss acceleration at the Southern Antarctic Peninsula detected

ESA posted an update on Antarctic ice loss on 22 May 2015. Above animation shows how warm ocean water penetrates the glacier grounding line through basalt melt, threatening speed up of glaciers, discharged into the ocean. A recent acceleration in ice loss in a previously stable region of Antarctica has been detected by ESA’s ice mission. The…

This image explains what is wrong with climate change coverage in the USA

Yesterday Obama delivered a historic speech about national security and climate change, at a US coast guard academy. Additionally the White House released a report, which summed up the conclusions from security experts on climate change. Today, if you go to Google News and type in “climate change”, you get something like below picture, 593 media articles on…

The impacts of sea level rise on nuclear power plants

United States During the 1970s and 1980s, when many nuclear reactors were first built, most operators estimated that seas would rise at a slow, constant rate.  During Superstorm Sandy waves came close to reaching the Salem 1 nuclear reactor at Lower Alloways Creek, New Jersey. While it’s not clear how many current plants will still…

Jeremy Jackson: Sea Level Rise is Dangerous

By Daniel L. Kuester, U.S. Naval War College Public Affairs Feb. 4, 2015 NEWPORT, R.I. – Author, researcher and marine biologist Jeremy Jackson gave a presentation titled “Sea Level Rise is Dangerous” at U.S. Naval War College (NWC), Feb. 3, addressing environmental changes and the implications of those events on people. “The threats to the…

Sea Level Rise Projections until 2100, a nonlinear response?

Past sea level rise is not captured by models yet, in particular the response from ice sheets in Antarctica due to global warming. Projections therefore can often be regarded to potentially underestimate future sea level rise. For example, Overpeck et al. (2006), and Hansen (2007) suggest possibilities which could eventually lead to a nonlinear response…

Climate denial and climate communication #Denial101

ClimateProgress  What’s the best way to show a climate change denier the error of their ways? A new online course answers this question for the masses. Hint: it’s not lobbing an endless stream of scientific evidence that proves human-driven climate change. While this approach may be cathartic, telling those who refuse to accept climate science…

Climate Change with George Monbiot and George Marshall | Guardian Live

Despite the overwhelming evidence, the majority of us have become increasingly adept at ignoring or side-lining climate change. Most of us recognise the danger is real and yet we do nothing to stop it. As the Guardian sets out on its own climate change journey, George Marshall, one of the most eminent thinkers in the…

A journey from 5°C to 2°C – Glen Peters, CICERO

5C is the temperature increase above pre-industrial levels we are heading for if we follow our path of limited or no climate policy. 2C is the temperature increase above pre-industrial levels that most countries around the world have agreed would prevent dangerous climate change. This journey will describe how the energy system must change if…

NASA: Vast Antarctic ice shelf a few years from disintegration

NASA has found that the last section of Antarctica’s Larsen B Ice Shelf is likely to disintegrate before the end of the decade. Transcript: We know that this ice shelf existed for at least 11 to 12 thousand years. In 2002, two-thirds of it collapsed in less than six weeks. In the intervening period between…

Ocean May Be Melting Totten Glacier Says Study

Ocean access to a cavity beneath Totten Glacier in East Antarctica http://www.nature.com/ngeo/journal/v8/n4/full/ngeo2388.html Totten Glacier, the primary outlet of the Aurora Subglacial Basin, has the largest thinning rate in East Antarctica1, 2. Thinning may be driven by enhanced basal melting due to ocean processes3, modulated by polynya activity4, 5. Warm modified Circumpolar Deep Water, which has…
