You’ve probably heard by now how this new story circulating this week claims “record warmth” and that we are in the peak time of melting. Meanwhile, “back at the ranch”, sea ice extent continues a steady upward climb as shown above.
Scientists Counter Latest Arctic ‘Record’ Warmth Claims as ‘Pseudoscience’ – Comprehensive Arctic Data Round Up – October 17, 2008
Claim: Newspaper article claims Arctic Temps Peak in November – Claims Arctic offers ‘early warning signs’ – McClatchy Newspapers – October 16, 2008
Excerpt: Temperatures in the Arctic last fall hit an all-time high – more than 9 degrees Fahrenheit (5 degrees Centigrade) above normal – and remain almost as high this year, an international team of scientists reported Thursday. “The year 2007 was the warmest year on record in the Arctic,” said Jackie Richter-Menge, a climate expert at the Cold Regions Research and Engineering Laboratory in Hanover, N.H, and editor of the latest annual Arctic Report Card. “These are dynamic and dramatic times in the Arctic,” she said. “The outlook isn’t good.” Arctic temperatures naturally peak in October and November, after sea ice shrinks during the summer. […] Scientists say these changes in the Arctic are early warning signs of what may be coming for the rest of the world’s climate.
Arctic Reality Check: Why isn’t the cooling Antarctic considered ‘an indicator of what might happen to the rest of the world?’

Here is an fun press release I ran across on prweb.com. If Ms. Haseltine is successful in her project, we might see more local produce on the Grand Central Station Oyster Bar menu. But will it actually do anything about global warming?
Professor Uses Oysters to Teach College Students to Curb Global Warming
Internationally acclaimed environmental artist Mara G Haseltine joined NYC’s The New School for Liberal Arts to teach, Oyster Gardens, the only class of its kind worldwide where the students will focus on the design and planning of a floating oyster colony, an innovative public art project which merges art, sustainable design and field science.
New York, NY (PRWEB) October 16, 2008 — Internationally acclaimed environmental artist Mara G Haseltine joined NYC’s The New School for Liberal Arts to teach Oyster Gardens, the only class of its kind worldwide where the students will focus on the design and planning of a floating oyster colony, an innovative public art project which merges art, sustainable design and field science.
Oyster Gardens celebrates New York’s past as the oyster capital of the world boasting of 350 square miles of bio diverse oyster reef as well as to prepare it for a sustainable future with a bountiful biodiverse estuary. Students learn about the history and the biology of the Crassostrea Virginia, the indigenous oyster of New York, as well as traditional and new innovative methods of reef restoration. In this unique course students work hand in hand with a cross disciplinary team that includes marine engineers, marine biologists, along with conservation organizations to plan and design and a ‘moveable reef’ — a floating oyster colony that could be deployed around the harbor.
The idea is to bring back Crassotrea Virginica to New York, which would create a natural filtration system that cleans the waters and simultaneously brings back biodiversity, that has been missing in New York’s waters and estuaries since the Industrial Revolution. Oysters are the backbone of the benthic habitat and can act as natural water treatment plants. The average oyster filters 5-25 gallons of “nutrient” rich water per day. The restoration of 100 square miles of reef would filter twenty seven billion tons of wastewater that flows into New York’s waterways annually. The reef would not only be a haven for oyster,s but would quickly become a diverse habitat for aquatic life of all forms, from gastropods to stripped bass.
