Letter sent to the Guardian:

Tony Blair says: "The blunt truth about the politics of climate change is that no country will want to sacrifice its economy in order to meet this challenge."

No, Tony, this is only true when countries are forced to compete for investment and jobs and businesses and financial markets threaten to move elsewhere if effective action is taken on climate change. Simultaneous action by all, or sufficient, governments removes the threat of disinvestment.

But Tony is right, politicians are not up to the task because they are trapped in the system of competition. Politicians have failed us. To address climate change will take we, the people of the world, leading the way by seeking agreement across national boundaries on the policies we wish to see implemented and giving our leaders an ultimatum - implement our Simultaneous Policy package or lose our support.

Such a campaign is being promoted by the International Simultaneous Policy Organisation, which has already received pledges from members of the UK and European Parliaments and Australian Senate to implement the Simultaneous Policy (SP) alongside other countries.

Join the campaign by signing up free of charge as an SP Adopter at  http://www.simpol.org.uk/ to increase the pressure for governments across the planet to support SP.
