ScienceDaily (Oct. 19, 2011) Rivers and streams in the United States are releasing substantially more carbon dioxide into the atmosphere than previously thought, according to researchers publishing their results in the current issue of the journal Nature Geoscience.

ScienceDaily (Dec. 7, 2009) In the long term, the Earth's temperature may be 30-50% more sensitive to atmospheric carbon dioxide than has previously been estimated, reports a new study published in Nature Geoscience.

The results show that components of the Earth's climate system that vary over long timescales -- such as land-ice and vegetation -- have an important effect on this temperature sensitivity, but these factors are often neglected in current climate models.

ScienceDaily (Nov. 27, 2009) The world's oceans are absorbing less carbon dioxide (CO2), a Yale geophysicist has found after pooling data taken over the past 50 years. With the oceans currently absorbing over 40 percent of the CO2 emitted by human activity, this could quicken the pace of climate change, according to the study, which appears in the November 25 issue of Geophysical Research Letters.

Researchers have taken a step towards making carbon nanotubes into transmission lines.

A new method for assembling carbon nanotubes has been used to create fibers hundreds of meters long. Individual carbon nanotubes are strong, lightweight, and electrically conductive, and could be valuable as, among other things, electrical transmission wires. But aligning masses of the nanotubes into well-ordered materials such as fibers has proven challenging at a scale suitable for manufacturing. By processing carbon nanotubes in a solution called a superacid, researchers at Rice University have made long fibers that might be used as lightweight, efficient wires for the electrical grid or as the basis of structural materials and conductive textiles.

VANCOUVER, British Columbia (Reuters) - Spectators, media and sponsors planning to attend next year's Winter Olympics in Vancouver will be under pressure to offset their carbon emissions, organizers said on Tuesday.

The Vancouver Organizing Committee (VANOC), which has vowed to make the 2010 Games carbon neutral, unveiled plans to reduce the 150,000 tonnes of indirect greenhouse gas emissions expected to be produced as a result of the event.

Researchers in Arkansas have found that exposing tomato seeds to carbon nanotubes makes tomato plants sprout earlier and grow more quickly. They write in the journal ACS Nano that these results, though preliminary, suggest that carbon nanotubes could be a boon for the agriculture and biofuel industries and lead to new types of fertilizers

SYDNEY (Reuters Life!) - Hollywood star Eric Bana and the producers of his new motor-racing movie have teamed up with an Australian environmental group to offset the pollution caused during filming, saying they love cars but love the planet more.
