From the Australian ONE vision for the the future of motoring in a carbon challenged world has gone on display at the Australian International Motor Show in Sydney, with GM Holden revealing the Volt electric car. General Motors recently confirmed plans to sell the Volt in the United States from late 2010. It can travel Continue Reading →

THE future of coal-fired power generation in Europe has been called into question after the European Union backed laws that would force power companies to pay for all their carbon dioxide emissions from 2013.
The decision, which could cost the power industry E30 billion ($56 billion) a year and could trigger a steep rise in electricity bills, represents a huge boost for the renewable energy industry.
Chris Davies, an MEP who supported the legislation, said the decision by the EU’s environment committee “effectively prevents the building of new coal-fired power plants from 2015 unless equipped with CCS (carbon capture and storage technology)”.
From the Land Supplies of farm chemicals are running tight as crop producers battle to control a spring flush of winter crop pests and diseases. Aerial spraying operators, who have pulled out all stops containing an unprecedented epidemic of stripe rust, have now joined the fight against the latest outbreaks of aphids in canola, ascochyta Continue Reading →
ENVIRONMENTAL groups and the Bush administration yesterday reached a partial court settlement that requires the Department of Interior to designate critical habitat for polar bears by June 30, 2010. The Department of Interior in May listed the polar bear as being threatened by global warming, but did not designate any critical habitat protection. The Centre Continue Reading →

The burning of fossil fuels — notably coal, oil and gas — has accounted for about 80 percent of the rise of atmospheric carbon dioxide since the pre-industrial era. Now, NASA researchers have identified feasible emission scenarios that could keep carbon dioxide below levels that some scientists have called dangerous for climate.

When and how global oil production will peak has been debated, making it difficult to anticipate emissions from the burning of fuel and to precisely estimate its impact on climate. To better understand how emissions might change in the future, Pushker Kharecha and James Hansen of NASA’s Goddard Institute for Space Studies in New York considered a wide range of fossil fuel consumption scenarios. The research, published Aug. 5 in the American Geophysical Union’s Global Biogeochemical Cycles, shows that the rise in carbon dioxide from burning fossil fuels can be kept below harmful levels as long as emissions from coal are phased out globally within the next few decades.
