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.

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 […]
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, […]
Contact: Barnaby Smithbpgs@ceh.ac.uk44-792-029-5384 A new study shows that as climate change enhances tree growth in tropical forests, the resulting increase in litterfall could stimulate soil micro-organisms leading to a release of stored soil carbon. The research was led by scientists from the Centre for Ecology & Hydrology and the University of Cambridge, UK. The results […]
Study suggests black carbon pollution has greater effect than carbon dioxide on region’s ice By Janet RaloffMarch 8th, 2011 In high-elevation snowy regions, the warming effects of greenhouse gases pale in comparison to those triggered by soot, new computer calculations show. The finding could help explain the accelerating pace of melting on the Tibetan Plateau, […]
Caption by Holli RiebeekFebruary 22, 2011 Dense smog settled over the North China Plain on February 20, 2011. The featureless gray-brown haze is so thick that the ground is not visible in parts of this photo-like image taken at 11:35 a.m. by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. At that time, […]
Caption by Holli Riebeek and Adam Voiland9 November 2010 Of all the pollution that fills our lungs on any given day, the most dangerous is the small stuff. Aerosol particle pollution—airborne solid particles and liquid droplets—comes in a range of sizes. Particles smaller than 2.5 micrometers pose the greatest risk to human health because they […]
(Rice University) A new study by geochemists at Rice University finds that damming and other human activity has completely obscured the natural carbon dioxide cycling process in Texas’ longest river, the Brazos. “The natural factors that influence carbon dioxide cycling in the Brazos are fairly obvious, and we expected the radiocarbon signature of the river […]
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new assessment in the September 2008 issue of BioScience. The […]
