Is based on the idea that if CO2 level increases are not stopped within 98 months (it was launched two months ago) we will reach a tipping point and from then on it's runaway climate change...
They link to a Guardian feature on this: http://www.guardian.co.uk/environment/2008/aug/01/...
Which I read and a PDF report which I haven't yet read: http://www.neweconomics.org/gen/uploads/sbfxot55p5...
The Guardian article is basically advocating a "Green New Deal":
So what can our own government do to turn things around today? Over the next 100 months, they could launch a Green New Deal, taking inspiration from President Roosevelt's famous 100-day programme implementing his New Deal in the face of the dust bowls and depression. Last week, a group of finance, energy and environmental specialists produced just such a plan.
Addressed at the triple crunch of the credit crisis, high oil prices and global warming, the plan is to rein in reckless financial institutions and use a range of fiscal tools, new measures and reforms to the tax system, such as a windfall tax on oil companies. The resources raised can then be invested in a massive environmental transformation programme that could insulate the economy from recession, create countless new jobs and allow Britain to play its part in meeting the climate challenge.
Goodbye new airport runways, goodbye new coal-fired power stations. Next, as a precursor to enabling and building more sustainable systems for transport, energy, food and overhauling the nation's building stock, the government needs to brace itself to tackle the City. Currently, financial institutions are giving us the worst of all worlds. We have woken to find the foundations of our economy made up of unstable, exotic financial instruments. At the same time, and perversely, as awareness of climate change goes up, ever more money pours through the City into the oil companies. These companies list their fossil-fuel reserves as "proven" or "probable". A new category of "unburnable" should be introduced, to fundamentally change the balance of power in the City. Instead of using vast sums of public money to bail out banks because they are considered "too big to fail", they should be reduced in size until they are small enough to fail without hurting anyone. It is only a climate system capable of supporting human civilisation that is too big to fail.
