Various: International attendes of the President's climate change meeting, which looked at creating voluntary caps on cardon dioxide emissions came away disappointed in the US position says the BBC. British climate envoy, John Ashton, said the US seemed isolated on the issue of fighting climate change. "I think that the argument that we can do this through voluntary approaches is now pretty much discredited internationally," he told the Reuters news agency.

Meanwhile the Guardian reports that paintings containing sunsets by artists such as JMW Turner are being analyzed to work out the cooling effects of huge volcanic eruptions. By working out how the climate varied naturally in the past they hope to improve the computer models used to simulate global warming, which in turn will effect discussions at the upcoming post-Kyoto climate talks.
