Relative composition of the periphytic diatom assemblages along the CO2 gradient, including all genera present over 1% and with all unidentified diatoms grouped as unidentified pennate or naviculoid. Between September 2009 and October 2010, mean surface seawater pH decreased with increasing proximity to CO2 vents (S1 = 8.18, S2 = 8.05, S3 = 7.49, n […]
20 November 2011 (Desdemona Despair) – Here’s Desdemona giving a presentation on the accelerating destruction of the oceans by various human activities. It’s basically Graph of the Day with narration.

a, Krill density in the SW Atlantic sector (4,948 stations in years with >50 stations). Temporal trends include b, post-1976 krill data from scientific trawls; c, 1926–2003 circumpolar salp data south of the SB. Regressions of log10(mean no. m-2) on year were calculated for cells with ≥3 years of data, weighted by number of stations […]
Athens, Georgia, October 26 (SPX) – Increasing acidification in coastal waters could compromise the ability of oysters and other marine creatures to form and keep their shells, according to a new study led by University of Georgia researchers. Their findings will be published in the November 2011 issue of Nature Geoscience. The researchers determined the […]
Contact: David DeFusco, david.defusco@yale.edu, 203-436-484217 October 2011 New Haven, Connecticut – Rivers and streams in the United States are releasing enough carbon into the atmosphere to fuel 3.4 million car trips to the moon, according to Yale researchers in Nature Geoscience. Their findings could change the way scientists model the movement of carbon between land, […]
Media Contact: Todd McLeish, 401-874-7892 11 October 2011 KINGSTON, R.I. – While the cause of the mass extinction that occurred between the Permian and Triassic periods is still uncertain, two University of Rhode Island researchers collected data that show that terrestrial biodiversity recovered much faster than previously thought, potentially contradicting several theories for the cause […]
[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. […]
By Seth Koenig, BDN Staff7 October 2011 SOUTH PORTLAND, Maine — They’re called dead muds. Rising levels of carbon dioxide in the atmosphere combined with unregulated nitrogen pollution are having a deadly effect on Maine’s shellfish, some researchers say. Scientists are starting to measure the impact of increasingly acidic waters on coastal organisms, and what […]
By Hayley Baker 6 October 2011 We’ve been investigating overfishing in West African waters for a long time and our new report, Empty Nets, Empty Future shows, in a stark light, how the local fishing industry in West Africa is under threat. The report focuses on how millions of Senegalese people depend on the fish […]
[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 […]
