IPCC AR5 Admits They Have No Clue About the Arctic and the Antarctic

From the leaked AR5 Summary:

There is robust evidence that the downward trend in Arctic summer sea ice extent since 1979 is now better simulated than at the time of the AR4, with about one-quarter of the models showing a trend as large as, or larger than, the trend in the observations. Most models simulate a small decreasing trend in  Antarctic sea ice extent, albeit with large inter-model spread, in contrast to the small increasing trend in 30 observations. {9.4.3}

“one-quarter of the models showing a trend as large as, or larger than, the trend in the observations”

Translation: 75% of the models were wrong about Arctic Sea Ice. But we’ll claim we got it right when we only got it right 25% of the time.

“Most models simulate a small decreasing trend in  Antarctic sea ice extent

Translation: None of the models got Antarctic Sea Ice right.

What a joke.

  1. Only 25% of the models? I have a better change to be right when playing black or red in Roulette.

    Their whole assumption is based on CO2 being the driver. WRONG. The last 15 years show that this is not the case. I know they say that you need to have at least 30 years.

    The Club of Rome described the CO2 issue in the bookf “The Limits to Growth”, which was published in 1972. At that time the media was focused on global cooling.

    On page 73 – If the energy source is something other than incident solar energy (e.g., fossil fuels or atomic energy), that heat will result in warming the atmosphere,. …
    This was the blue print for the Green parties, the IPCC,etc.
