Hansen campaigns vigorously and vociferously against coal fired power stations as the single most climate polluting artifact of our modern economies. Simply, they spew out billions of tons of CO2 (and other nasties, but we won't go into that right now!) around the world every year and we continue to build them despite that knowledge. "The single greatest threat to civilisation and all life on our planet."
Al Gore is quoted as saying, "I can't understand why there aren't rings of young people blocking bulldozers and preventing them from constructing coal-fired power stations."
In this article from The Guardian, he attacks the UK government for continuing to support the building of new coal-fired power stations in Britain. But he also has a go at the Australian government too. And rightly so.
"The Australian government was elected on a platform of solving the climate problem, but then, with the help of industry, it set emission targets so high as to guarantee untold disasters for the young, let alone the unborn. These governments are not green. They are black - coal black."This is a good read to get up to speed on the coal/power station issue.
Update 24 Feb 09. Adding here a video from Hansen. Not so much interested in the invitation to join the event he's announcing, but in the continuing focus on coal (and other fossil fuels) as the place we must concentrate our efforts to reduce carbon pollution.
