Razorlight are headlining a rally in London�s Trafalgar Square today to campaign against global warming.

The rockers have agreed to support the �Stop Climate Chaos� event, which is campaigning for a bill to be introduced into parliament aimed at battling the source of green house gasses � such as Johnny Borrell�s gob.

KT Tunstall is also pencilled in to speak at the event - which comes as global talks in Nairobi, Kenya take place later this month � with proceedings scheduled to get going around 1pm.
