Andy Dessler: Uncertainty over how bad Global Warming will get

This is quote of the week for me. Andy Dessler, who got it wrong with his rebuttal of Roy Spencer and Danny Braswell’s paper on cloud feedback last year, said this in an interview with PBS:

There is some legitimate uncertainty, of course, but that is whether the climate will warm four or eight degrees over the coming century.

Now, I don’t know which planet Andy is personally in orbit around, but it sure isn’t the one I’m living on. I assume he’s talking in Fahrenheit here rather than Centigrade, but talk of warming of this magnitude on any temperature scale is all Greek to me. Steady as she goes Andy, don’t pop a fuse.

More of Andy’s inanity here:

  1. oldbrew says:

    Just another warm-monger.

  2. Brian H says:

    Ooo, I’d love to be around in 2100 to collect on a bet (to be made with any Dressler disciple) that the increase in temperature will be much closer to 1° than 8°. His choice of C or F scale.

  3. Brian H says:

    Edit: Dessler, of course. Murphy and Muphry strike again.

  4. Joe's World(progressive evolution) says:


    Scientists still don’t understand water.
    It is one of the most important factors to keep a stable temperature through the coldness of night and the heat of day.

    They don’t acknowledge angles and solar penetration in planetary tilting.
    Seemed also to have missed the dips and valley of pressure since it is only covering the density of water that we record.
    Different velocities also are of no consequence.

    And these models that miss very many factors are suppose to predict the future.
    What they are actually doing is recording and projecting.
    Is that science?
    No, it is statistical analysis.

    Our planet made science simple and generated complexity with age.

    Water balance currently today is NOT the same in the past nor will it be in the future.
    The less water and the more heat absorption into the rock and planet life.
    The more water and the colder the planet.
    What is the temperature of water with depth?

    It IS a different density to the atmosphere and the time parameters are very much slower than the atmosphere itself. Change it to vapor and it changes time lines of heat and cold depending on how much vapor is present.

  5. AGW promoters often speak of skeptics’ associations as a way of disqualifying skeptics. But does his own association with an AGW-promoting organizations then a good excuse to disqualify him?

    In case there is any doubt about Dessler’s opinions about skeptics, you can see that in my piece from last year, “Google to fight global warming ‘ignorance’ ”
