A long-lasting drought that affected the Amazon Rain Forest last year was worse than the once-in-a-lifetime drought that the region suffered in 2005, and a team of British and Brazilian scientists say it may have a bigger impact on global warming than the US does in a year. The widespread drought has raised concerns about the rainforest's future as a major absorber of carbon emissions, the scientists said in a study released Thursday. Frequent severe dry spells like the ones in 2005 and...

By Anne M Stark, LLNL Using seawater and calcium to remove carbon dioxide (CO2) in a natural gas power plant's flue stream, and then pumping the resulting calcium bicarbonate in the sea, could be beneficial to the oceans' marine life. Greg Rau, a senior scientist with the Institute of Marine Sciences at UC Santa Cruz and who also works in the Carbon Management Program at Lawrence Livermore National Laboratory, conducted a series of lab-scale experiments to find out if a seawater/mineral...

Science have probed the climate secrets of the Marianas Trench in the western Pacific Ocean. The international team used a submersible, designed to withstand immense pressures, to study the bottom of the deepest part of the ocean. The scientist early results reveal that ocean trenches are acting as carbon sinks. This suggests that they play a larger role in regulating the Earth's chemistry and climate than what was previously thought. Although explorers Jacques Piccard and Don Walsh...

The Pacific Forest Trust commends California's leadership in creating the nation's first economy-wide cap and trade program that will be the first compliance carbon market in the world to accept emissions reductions from forest carbon projects. Sacramento, CA (PRWEB) December 20, 2010 The Pacific Forest Trust (PFT) commends the California's Air Resources Board's Dec. 16 adoption of a set of regulations that will govern the state's landmark cap and trade system. The board's nine-to-one vote...

LONDON, Dec. 14, 2010 /PRNewswire/ -- Tucan Travel is thrilled to announce that in the two years since it introduced its carbon offset scheme, it has raised 34,000 GBP through clients and its own donations for the World Land Trust and its work restoring and protecting rainforests. Tucan Travel also saw the percentage of clients contributing to the carbon offset scheme nearly double from 14% in the first year to 27% this year. As a result, total contributions rose 28% to a total of over...

Leaks from carbon dioxide injected deep underground to help fight climate change could bubble up into drinking water aquifers near the surface, driving up levels of contaminants in the water tenfold or more in some places, according to a study by Duke University scientists. Based on a year-long analysis of core samples from four drinking water aquifers, "We found the potential for contamination is real, but there are ways to avoid or reduce the risk," says Robert B. Jackson, Nicholas...

Nature's capacity to store carbon, the element at the heart of global climate woes, is steadily eroding as the world's farmers expand croplands at the expense of native ecosystem such as forests. The tradeoff between agricultural production and maintaining nature's carbon reservoirs "“ native trees, plants and their carbon-rich detritus in the soil "“ is becoming more pronounced as more and more of the world's natural ecosystems succumb to the plow. The problem, experts say, is...

Eggshell membrane can absorb 7 times its weight in carbon dioxide The food industry generates a lot of waste products, but one of these, eggshells, could help combat climate change, according to research published in the International Journal of Global Warming this month. Basab Chaudhuri of the University of Calcutta and colleagues have demonstrated that the membrane that lines an eggshell can absorb almost seven times its own weight of the greenhouse gas carbon dioxide from the atmosphere....

New University of Florida research puts to rest the mystery of where old carbon was stored during the last glacial period. It turns out it ended up in the icy waters of the Southern Ocean near Antarctica. The findings have implications for modern-day global warming, said Ellen Martin, a UF geological sciences professor and an author of the paper, which is published in this week's journal Nature Geoscience. "It helps us understand how the carbon cycle works, which is important for...

Emissions of carbon dioxide are causing ocean acidification as well as global warming. Scientists have previously used computer simulations to quantify how curbing of carbon dioxide emissions would mitigate climate impacts. New computer simulations have now examined the likely effects of mitigation scenarios on ocean acidification trends. They show that both the peak year of emissions and post-peak reduction rates influence how much ocean acidity increases by 2100. Changes in ocean pH over...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
