image: Carnegie Institution We've written about the phenomenon of outsourced carbon emissions a number of times, with the example of perhaps up to one third of China's emissions coming from manufacturing goods destined for consumption abroad being most prominent. Well, a new study by scientists at the Carnegie Institution adds some more data to our our understanding of this issue:...Read the full story on TreeHugger

Image: Angewandte Chemie, Wiley Sunlight + Water = Hydrogen Gas Scientists at the University of East Anglia, led by Dr. Thomas Nann, report a breakthrough in the production of hydrogen from water using the energy of sunlight. Amidst all the hype about a potential hydrogen economy, which would rely upon the highly energetic and clean burning hydrogen atom, one of the big questions has been whether sufficient hydrog...Read the full story on TreeHugger

Photo via Wikimedia Ocean "dead zones" have been a mystery for scientists to understand. Their new tool in trying? Dead pigs. Scientists are "piggybacking" on forensics research to study oxygen-poor zones in oceans, with pigs as the animal of choice because of what turns out to be remarkable similarities between pig and human anatomy. Their skin is almost hairless, their bodies similar in size, and apparently their flesh h...Read the full story on TreeHugger

Scientists took sonar measurements to record clouds of methane bubbles rising from the seafloor. Photo: Igor Semiletov, University of Alaska More evidence is emerging that methane previously trapped in the permafrost below the Arctic sea is starting to be released into the oceans and potentially into the atmosphere. Research published in Science shows that up to 7 million tons of methane is released annually from the East Siberian...Read the full story on TreeHugger
