Tropical ecosystems regulate variations in Earths carbon dioxide levels
2013-07-28 16:46:00| Climate Ark Climate Change & Global Warming Newsfeed
CSIRO: The study, published in the journal Proceedings of the National Academy of Sciences, found that a temperature anomaly of just 1C (in near surface air temperatures in the tropics) leads to a 3.5-Petagram (billion tonnes of carbon) anomaly in the annual CO2 growth rate, on average. This is the equivalent of 1/3 of the annual global emissions from the combustion of fossil fuels and deforestation together. Importantly, the NASA Earth Exchange (NEX) study results provide scientists with a new diagnostic...

Tropical Ecosystems Boost Carbon Dioxide as Temperatures Increase
2013-07-25 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Unlike in other parts of the word, tropical ecosystems are capable of generating significant carbon dioxide when temperatures rise, an international team of researchers has found. Specifically, the scientists discovered that a temperature increase of just 1 degree Celsius in near-surface air temperatures in the tropics results in an average annual growth rate of atmospheric carbon dioxide that is equivalent to one-third of the annual global emissions caused by the combustion of fossil fuels and...

Could carbon dioxide be converted to electricity?
2013-07-25 17:13:00| Climate Ark Climate Change & Global Warming Newsfeed
Mother Nature Network: Here's an interesting idea: What if the carbon dioxide (CO2) produced by power plants while they generate electricity could be converted into a source of additional electricity? That's the idea behind a new paper published this week in the journal Environmental Science & Technology Letters. Written by a team of researchers in the Netherlands, the paper describes how CO2 could be mixed with a fluid electrolyte, generating electrical energy in the process. A press release from the American Chemical...

High carbon dioxide spurs wetlands to absorb more carbon
2013-07-16 03:17:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Under elevated carbon dioxide levels, wetland plants can absorb up to 32 percent more carbon than they do at current levels, according to a 19-year study published in Global Change Biology from the Smithsonian Environmental Research Center in Edgewater, Md. With atmospheric CO2 passing the 400 parts-per-million milestone this year, the findings offer hope that wetlands could help soften the blow of climate change. Plant physiologist Bert Drake created the Smithsonian's Global Change Ecological...
