And to end you day on a uber-depressing note, sure to give you at least some nightmares Scientists studying Caribbean reefs say that 2010 may be the worst year ever for coral death there. Abnormally warm water since June appears to have dealt a blow to shallow and deep-sea corals that is likely to . . . → Read More: Caribbean Coral Die-Off Could Be Worst Ever
An occasional series where we briefly report 3 new studies and tell you why they are cool! A new paper by Boyce, Lewis, and Worm from Dalhousie University, provides clear evidence of decreasing phytoplankton biomass over the last century. The researchers used a blended dataset of ~450,000 measurements of chlorophyll consisting of field measurements of . . . → Read More: The Tide Pool: Loss of Phytoplankton, War Gods and Corals, and Gulf of Mexico Biodiversity
…in 2010 despite recent minimum of solar iridescence. “We conclude that global temperature continued to rise rapidly in the past decade” and “there has been no reduction in the global warming trend of 0.15-0.20°C/decade that began in the late 1970s.” Blue curve: 12-month running-mean global temperature.

That’s pretty much the message of new study in Geophysical Research Letters. Large deposits of methane hydrates, i.e. methane ice, occur naturally in the seafloor sediments of the Arctic continental shelf between 300-600 meters. This is dominate reservoir for methane due to the large area and extremely low temperatures. The continued and predicted warming of . . . → Read More: Ocean Warming Melts Methane Hydrates Which Screws Us All
Hell yes Graph from NASA: The continent of Antarctica has been losing more than 100 cubic kilometers (24 cubic miles) of ice per year since 2002.

Perhaps fish-poo-covered-bacterial-ooze-slime-haven-so-salty-I-puke-in-my-snorkel-every-time-it-touches-my-tongue? Well, the definition of seawater has been limited by how we can measure it and what type of information that we wish to glean from knowing something about seawater.

From the New York Times… The House passed legislation on Friday intended to address global warming and transform the way the nation produces and uses energy. The vote was the first time either house of Congress had approved a bill meant to curb the heat-trapping gases scientists have linked to climate change. The legislation, which . . . → Read More: Moving forward too slowly?
BERLIN (AFP) — Indian and German scientists have said that a controversial experiment has “dampened hopes” that dumping hundreds of tonnes of dissolved iron in the Southern Ocean can lessen global warming. The experiment involved “fertilising” a 300-square-kilometre (115-sqare-mile) area of ocean inside the core of an eddy — an immense rotating column of water . . . → Read More: Iron Fertilization Will Not Help Global Warming
