A NEW worldwide movement backed by celebrities, musicians, politicians and business leaders is aiming to reverse the effects of global warming over the next decade.

Global Cool launched in London and LA today and is calling on one billion people to reduce their carbon emissions by just one tonne a year, for the next 10 years.

Boffins have found the climatic tipping point - when the climate becomes irreversibly damaged - can be turned back if global CO2 emissions are reduced by one billion tonnes a year.

Campaigners then hope cleaner, renewable energy sources such as solar, wind, water and hydrogen would have been developed.

Big names including Leonardo Di Caprio, Orlando Bloom, KT Tunstall, Pink, The Killers, Razorlight and Josh Hartnett have thrown their weight behind the worldwide effort to beat climate change.

A website has been set up, www.global-cool.com, with advice on how to go green by reducing energy consumption through doing simple things such as sharing a shower with a mate.

Big business have donated £120m to support the campaign while MySpace will push the message out to its millions of subscribers.

Dan Morrell, Founder of Global Cool said: "Over the next 10 years Global Cool will give everyone the tools and knowledge to actively decrease their own CO2 emissions and show them how to encourage others to do the same.

"Together we can actively create a global movement committed to pushing back the climatic tipping point, delivering a sustained long term, benign future without the worst effects of climate change."

Tomorrow Global Cool founders will meet the Prime Minister at Downing Street and 50 of the world's top business leaders to push their cause.
