Obama: Subtle Change In Emphasis?

'Denying climate change is like saying the moon is made of cheese.' argues Obama. 

I have never met anyone who denies 'climate change.' There is however a most worthy case to be made against the 'global warming' hypothesis based on the compelling evidence of there having been no worldwide temperature hikes over some 16 years. What Obama does is to mingle two different arguments. Even if he were correct, linking this to man's activities ahead of volcanic output has never been proved. My experiences of life in the 50s and 60s convince me that Man today is damaging the atmosphere far less than he has done in many decades of industrialisation.
