John Marburger reiterates to the BBC that that greenhouse gases cause 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....

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 unliveable.

Marburger has admitted before that the climate is changing, but this is the strongest statement I can recall from him about man's role in it. But, in a somewhat illogical conclusion, he's still not sure we should do anything about it:

It's not clear that we'll be in a position to predict the future accurately enough to make policy confidently for a long time," he said.

"I think 2C is rather arbitrary, and it's not clear to me that the answer shouldn't be 3C or more or less. It's a hunch, a guess."

The truth, he said, was that we just do not know what the 'safe' limit is.

How can you believe that the atmosphere will just get "hotter and hotter" and yet still refrain from action?
