Models aren't realistic simulations of climate
(1936) An expert in atmospheric boundary layer processes who pioneered the development of numerical weather prediction, this Dutch atmospheric scientist and AGW skeptic was the former director of research at Royal Dutch Meteorological Institute.
He thinks Gore exagerates
"I find the Doomsday picture Al Gore is painting - a six-meter sea level rise, fifteen times the IPCC number - entirely without merit …. I protest vigorously the idea that the climate reacts like a home heating system to a changed setting of the thermostat: just turn the dial, and the desired temperature will soon be reached."
A Skeptical View of Climate Models
He is a key critic of climate models. To get a feel for his approach, click here to read his essay A Skeptical View of Climate Models.
Excerpt: "The blind adherence to the harebrained idea that climate models can generate 'realistic' simulations of climate is the principal reason why I remain a climate skeptic.
From my background in turbulence I look forward with grim anticipation to the day that climate models will run with a horizontal resolution of less than a kilometer. The horrible predictability problems of turbulent flows then will descend on climate science with a vengeance."
“Why does the IPCC ignore the oceans? The top 2½ meters of all sea-water contain as much heat as the total amount of heat in the atmosphere. Why has the topmost kilometre of the oceans turned colder during the last five years? [as of 2010] We don’t know. Until we understand what is happening with the heat in the oceans, the models which aim to predict the climate are totally useless." (Source)

He was also a member of the Royal Netherlands Academy of Arts and Sciences from 1982 until his recent withdrawal in January, 2010, after accusing the RNAAS of misrepresenting science." (Source)
