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 […]

By Seth Borenstein5 November 2011 WASHINGTON (AP) – The global output of carbon dioxide jumped by the biggest amount on record, the US Department of Energy has calculated, a sign of how feeble the world’s efforts are at slowing man-made global warming. The new figures for last year mean that levels of greenhouse gases are […]
By Stephen Gardiner20 October 2011 Sometimes the best way to make progress on a problem is to get clearer on what that problem is. Arguably, the biggest issue facing humanity at the moment is the looming global environmental crisis. Here, the problem is not that we are unaware that trouble is coming. After all, the […]
By Brandon Keim 26 October 2011 When searching for causes of Earth’s mass extinctions, scientists instinctively turn to geophysical calamities: erupting volcanoes, methane bursts, asteroid strikes, and other obvious dooms. But in the most massive extinction of all, when most of everything that lived died out some 250 million years ago, a more subtle form […]
October 19 (U. of Copenhagen) – Rising sea levels in the coming centuries is perhaps one of the most catastrophic consequences of rising temperatures. Massive economic costs, social consequences and forced migrations could result from global warming. But how frightening of times are we facing? Researchers from the Niels Bohr Institute are part of a […]
By Richard A. Kerr 21 October 2011 The bad news just got worse: A new study finds that reining in greenhouse gas emissions in time to avert serious changes to Earth’s climate will be at best extremely difficult. Current goals for reducing emissions fall far short of what would be needed to keep warming below […]
By Ulrika Jönsson Belyazid 21 October 2011 A common argument against global warming is that the climate has always varied. Temperatures rise sometimes and this is perfectly natural is the usual line. However, Svante Björck, a climate researcher at Lund University in Sweden, has now shown that global warming, i.e., simultaneous warming events in 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, […]
By Jim Bouldin14 October 2011 In 2004 Stephen Pacala and Robert Socolow published a paper in Science in which they argued that a pragmatic, but still difficult, way of stabilizing atmospheric CO2 levels over the long term was via the implementation of seven “stabilization wedges” over the next 50 years. The idea was very simple: […]
