Now we are finally getting to some acceptable and sort of logical arguments. Natural Variability of course cuts two ways. Year ago we we were asking how do you know the warming you are seeing is not part of natural variability. The answer is of course you do not know. Using the best statistical methods there has been no warming outside of natural variability since the industrial revolution.
Add to that these guys and their computer models can't even accurately predict tomorrows weather. Who in their right mind would assume they can predict the climate?
