Actually, the scary thing is, it seems to take a highly (or overly) educated mind to discard common sense.
The claim is that the globe has warmed over the last 20 years as sunspots remained constant.
However, climate has not warmed appreciably since the 1990s. So it appears a new equilibrium was reached several years ago - just as you and I surmised would happen - there would be a delay between increasing solar output to a new constant and the Earth reaching a new equilibrium. But that factiod is buried in the "20 year" claim - they lump 13 years of warming with 7 years of equilibrium. On purpose.
So the next big El Nino might be the next step in the climate step function, eh?
