The 1980-2000 IPCC Hiatus

In the 2001 IPCC report, both satellites and balloons showed no warming from 1980 to 2000.2016-01-04-17-05-54

As with the MWP, 1940’s blip, 1970’s global cooling and current hiatus – the 1980-2000 hiatus has simply disappeared.

    Facts have an annoying habit of getting in the way of a good narrative.

    No doubt someone will be along soon saying it’s the wrong graph or has been hand-drawn.

  3. Andy DC says:

    Save Martin the trouble of posting.

    “There never was no warming between 1980 and 2000. Why do you have to lie, even if the charts say you are telling the truth?”

  4. Rosco says:

    So the IPCC agree the hiatus is really from 1980 to 2016 ?

    • AndyG55 says:

      PRECISELY (as I just mentioned on JoNova)🙂

      36 years of NO WARMING !

    • AndyG55 says:

      Actually, there was a step change around the 1998 El Nino, of about 0.26ºC

      In RSS the trend in that 1979-1998 period is very small, just like the downward trend after the El Nino is small.

      But they essentially cancel themselves, leaving the El Nino as the ONLY warming in the last 36 or so years.

      • David A says:

        I do not think the step change will happen with the 2015-16 El Nino.

        1. The AMO is turning down.
        2. The RRR appears to be gone, and therefore the “blob” will likely cool; and so global SST will, I think, not respond up, and with a strong La Nina we may see a step down.

          Solar cycle 24 starting in 2009 certainly has been anemic. Another factor is Albedo/Clouds.

          Cloud cover correlates with global temperature (R^2 = 0. 28)

          Total monthly cloud cover 1983 to the end of 2009. (NASA has not updated info.) Note low cloud cover 1997 to 2000.

          High clouds

          Low clouds

          And Tropical (15oN-15oS) high (red) and low (purple) cloud cover

          I sure would like to see those graphs up to date!

    • AndyG55 says:

      Thing is, UAH shows basically the same as the top graph.

      Verification that UAH is CORRECT..
