Accelerated Ice Loss from Greenland


After little net change in the 1990s, Greenland is now melting and shedding billions of tons of ice, according to NASA satellite observations. This trend especially concerns scientists because meltwater and ice emptying into the ocean raise global sea level. Currently, sea level is increasing at about 1.25 inches per decade, and researchers estimate Greenland is contributing about 15% of this rate. Greenland holds a great deal of ice; if all of it returned to the ocean, sea level would rise about 23 feet. (Such a loss would take many centuries to play out, even with substantially more warming than today.)

Ice cap thaw will awaken Icelandic volcanoes?

An aerial handout photo from the Icelandic Coast Guard shows melting ice caused by a volcanic eruption at Eyjafjalla Glacier in southern Iceland April 14, 2010. The volcanic eruption on Wednesday partially melted a glacier, setting off a major flood that threatened to damage roads and bridges and forcing hundreds to evacuate from a thinly populated area.

Some scientists suggest that climate change and its consequences on Ice cap thaw in Iceland may awaken volcanoes in the future...

"Our work suggests that eventually there will be either somewhat larger eruptions or more frequent eruptions in Iceland in coming decades," said Freysteinn Sigmundsson, a vulcanologist at the University of Iceland.

"Global warming melts ice and this can influence magmatic systems," he told Reuters. The end of the Ice Age 10,000 years ago coincided with a surge in volcanic activity in Iceland, apparently because huge ice caps thinned and the land rose.

Celine Cousteau: Environmentalism Should be Taught in Schools

La science ne se fait pas sur des plateaux télé!

Il était grand temps que les scientifiques français se réveillent:

"Le coup de gueule contre Allègre des climatologues français":
Entre climatologues et climato-sceptiques, ça tourne à la guerre ouverte. Ce mercredi, plus de 400 scientifiques français ont adressé un appel à la ministre de la Recherche pour que cessent les remises en cause permanentes de leur travail par l'ancien ministre de l'Education...
« La lettre est adressée à Pécresse, mais nous ne demandons pas à la ministre de se prononcer sur le contenu scientifique. Nous visons avant tout les structures compétentes : l’Académie des sciences bien entendu, mais aussi les centres de recherche regroupés dans l’alliance AllEnvi qui travaillent sur le climat, CEA, CNRS, Météo France, INRA… », explique Jérôme Chappellaz, directeur de l’équipe climat au laboratoire de glaciologie et géophysique de l’environnement du CNRS à Grenoble et l’un des premiers signataires de l’appel.

Pour ces scientifiques, une telle sortie se donne avant tout comme objectif de recadrer le questionnement scientifique au sein d’un débat « serein ». « Allègre, Courtillot, Galam et compagnie sortent de ce cadre. La science ne se fait pas sur des plateaux télé, mais dans des journaux spécialisés. », cingle Jérôme Chappellaz.

Permafrost Line Recedes 130 Km In 50 Years

Quebec City, Canada (SPX) Feb 18, 2010
The southern limit of permanently frozen ground, or permafrost, is now 130 kilometers further north than it was 50 years ago in the James Bay region, according to two researchers from the Department of Biology at Universite Laval.

In a recent issue of the scientific journal Permafrost and Periglacial Processes, Serge Payette and Simon Thibault suggest that, if the trend continues, permafrost in the region will completely disappear in the near future.

Bill Gates on energy: Innovating to zero!

This is our moment!

Dear Friends,

NRDC is working hard to build a groundswell of support for the strongest possible climate bill, and I wanted to let you know about a powerful new viral media campaign that is giving us a huge lift in this effort. This is our Moment is a 3 minute video featuring NRDC Trustee Leonardo DiCaprio and a host of Hollywood celebrities urging people to speak out to urge the Senate to pass clean energy legislation that will create jobs, reduce our dependence on foreign oil, and limit global warming. The response to this online campaignhttp://www.nrdcactionfund.org/thisisourmoment/ , which was launched by NRDC's Action Fund, has been fantastic. The video, dubbed "The best PSA ever" by Rolling Stone online, has been played more than 1.6 million times through http://www.nrdcactionfund.org/thisisourmoment/ and the many other websites that embedded the video on their own pages. As of last Friday, more than 35,000 emails have been sent to senators in support of clean energy legislation had been sent through the NRDC Action Fund website. Take a look at http://www.nrdcactionfund.org/ and please pass it on!
