From the leaked AR5 Summary:

“The observed reduction in warming trend over the period 1998–2012 as compared to the period 1951–1 2012, is due in roughly equal measure to a cooling contribution from internal variability and a reduced trend in radiative forcing (medium confidence). The reduced trend in radiative forcing is primarily due to volcanic eruptions and the downward phase of the current solar cycle. However, there is low confidence in quantifying the role of changes in radiative forcing in causing this reduced warming trend. {Box 9.2; 10.3.1; Box 10.2}”

Translation: It was the sun. Or super secret volcanoes. Or something.

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.
