Warwick Hughes catches out the IPCC in their biggest lie yet, they even used a dark colour to show how bad they expected it to be. This is, like BoM predictions recently, an epic fail. Did they learn how to do this from the BBC? Or the other way around?

Dr Pat Michaels writing in Forbes last May drew attention to the fact that 33 years of NASA satellite temperature data demonstrates a cooling trend over far southern regions. For global lower troposphere temperature trend map.
Anthony Watts has recently blogged on this topic too.
I thought I would check what IPCC 1990 had to say about future temperature trends – they quoted three models which all showed both poles warming with their colour scale extending to 12 degrees C for a doubling of atmospheric carbon dioxide – great use of “flaming colour scheme”.
Lets say a doubling would see 560ppm atmospheric carbon dioxide as opposed to 280ppm pre-industrialization. On that basis we are ~35% of the way to doubling. It looks like a comprehensive fail for the IPCC in 1990.

What really happened? Bob Tisdale has it all:
MONTHLY SST ANOMALY MAP
The following is a Global map of Reynolds OI.v2 Sea Surface Temperature (SST) anomalies for October 2012. It was downloaded from the NOMADS website. The contour levels are set at 0.5 deg C, and white is set at zero.

(Global SST Anomaly = +0.266 deg C)
Color me cynical. Thanks to Warwick and Bob for putting us straight.
