Scissor Sisters are to reward fans who sign up to their campaign to stop global warming by sending them "cool" text messages. The TAKE YOUR MAMA band, who are backing charity Global Cool Foundation in its climate change fight, will deliver SMS information to those who sign up to the organisation's 'green' text alerts. Subscribers will receive two energy-saving SMS alerts every month, encouraging them to join the fight against global warming. Hollywood actors Sienna Miller, Josh Hartnett and Rosario Dawson are also involved in the environmental campaign, which is the brainchild of music producer DAN MORRELL.
