For the record-we deny nothing....at least regarding the idea that the climate can ever be ENTIRELY stable, one way or the other.
The Earth's temperature, as best we can tell, is today 0.5 degrees C above its 1979-2000 base.
But those predictions are fact dicey propositions. As this piece argues, while the climate is a "non-linear chaotic system", it in fact is prone to long periods of relative stability-it has been quite stable over the last ten thousand years (post the last Ice Age).
I deny this possibility.
