Dr James Hansen, the director of NASA's Goddard Institute for Space Studies, will lead the rally in Coventry on Thursday, which campaigners have billed as Climate Change Day of Action.
The protest closely follows a warning to politicians from
2,500 scientists at last week's climate science summit in Copenhagen.
Hansen
believes it is right for scientists to take a strong political stance.
The
rally in Coventry on Thursday has been billed by the campaigners as Climate Change Day of Action.
"We can no longer allow politicians and business to twist and ignore science," Hansen
told The Sunday Times.
"The scientists can connect the dots and define the implications of different policy choices and we should make clear those implications."
