Video: As Siberian permafrost melts, methane seeps out

Visit msnbc.com for breaking news, world news, and news about the economy December 30 (MSNBC) – Jim Maceda travels to Siberia to interview Sergei Zimov, who has published a series of scientific papers exposing the importance of permafrost and high-latitude carbon dioxide and methane emissions in the global carbon cycle. Zimov initiated the Pleistocene Park […]

Arctic methane: Is catastrophe imminent? – ‘Pushing the climate system harder than at any time in Earth’s history’

By JUSTIN GILLIS20 December 2011 In my article over the weekend about the climate risks from buried Arctic carbon, I omitted any discussion of one issue that sometimes appears in the news: methane deposits under relatively shallow seawater near the coasts of Siberia, Canada and Alaska. It was a purposeful omission because my piece focused […]

Permafrost thaw: ‘A chronic source of emissions that will last hundreds of years’

By JUSTIN GILLIS16 December 2011 FAIRBANKS, Alaska – A bubble rose through a hole in the surface of a frozen lake. It popped, followed by another, and another, as if a pot were somehow boiling in the icy depths. Every bursting bubble sent up a puff of methane, a powerful greenhouse gas generated beneath the […]

Rapid rise in Arctic methane shocks scientists – ‘Some plumes are 1 kilometer or more wide’

By Steve Connor14 December 2011 Dramatic and unprecedented plumes of methane – a greenhouse gas 20 times more potent than carbon dioxide – have been seen bubbling to the surface of the Arctic Ocean by scientists undertaking an extensive survey of the region. The scale and volume of the methane release has astonished the head […]

Thinking the unthinkable: Engineering Earth’s climate

[The usual Desdemona disclaimer: So the leaders of men conceived of their most desperate strategy yet.] 12 October 2011 A U.S. panel has called for a concerted effort to study proposals to manipulate the climate to slow global warming — a heretical notion among some environmentalists. In an interview with Yale Environment 360, Jane C. […]

World Catastrophe Map calls it quits

[Update: CatMap is Back, hurrah! Good Bye Hello] One of the brightest luminaries on the doomer landscape has withdrawn from the field, presumably to focus on building a doomstead. Here’s the final communiqué: Goodbye CatastropheMap is closed permanently. Feel free to enjoy our archives, and especially peruse the 2020 Foresight Prophecy Service. Free Guide to […]

Peter Ward: We’ve entered the Age of Mass Extinction – Goodbye fish and a whole lot more

By Scott Thill8 August 2011 Mass extinction is finally fighting its way back into the news cycle, thanks to recent scary reports on climate change from the International Programme on the State of the Ocean, the United Nations Environment Program and the July issue of Science. But University of Washington paleontologist Peter Ward has been […]

Carbon release to atmosphere 10 times faster than during mass extinction event 55 million years ago

Contact: Andrea Elyse Messer, 814-865-9481, http://live.psu.edu6 June 2011 University Park, Pennsylvania – The rate of release of carbon into the atmosphere today is nearly 10 times as fast as during the Paleocene-Eocene Thermal Maximum (PETM), 55.9 million years ago, the best analog we have for current global warming, according to an international team of geologists. […]

Scientists argue against conclusion that bacteria consumed Deepwater Horizon methane

ScienceDaily (May 26, 2011) — A technical comment published in the May 27 edition of the journal Science casts doubt on a widely publicized study that concluded that a bacterial bloom in the Gulf of Mexico consumed the methane discharged from the Deepwater Horizon well. The debate has implications for the Gulf of Mexico ecosystem […]

Arctic’s icy coastlines retreat as planet warms

By Wynne Parry, LiveScience Senior Writer17 April 2011 In the high latitudes, climate change projections must take a new factor into account: Ice. In the Arctic, the loss of sea ice is likely to have dramatic repercussions, including greater erosion, which can present problems for the people and economic activity in this region, according to […]
