Washington (TGW) - John Marburger, one of U.S. President George Bush's scientific advisers, said climate change is real and is likely caused by humanity.



He said he is 90% certain that greenhouse gas emissions are causing global warming.



"I think there is widespread agreement on certain basics, and one of the most important is that we are producing far more CO2 from fossil fuels than we ought to be. And it's going to lead to trouble unless we can begin to reduce the amount of fossil fuels we are burning and using in our economies,” he told the BBC in an interview.



"The CO2 accumulates in the atmosphere and there's no end point, it just gets hotter and hotter, and so at some point it becomes unlivable," he said.



"You only have two choices; you either have advanced technologies and get them into the marketplace, or you shut down your economies and put people out of work," he said.



The Bush administration has been resistant to joining the fight against climate change.
