This post will serve as part 2 of the 2015 update of the model-data comparisons of satellite-era sea surface temperatures. The 2014 update is here. This, the second part, contains time-series graphs.  But the data and model outputs are being presented in absolute, not anomaly, form.

INTRODUCTION

The climate models used by the Intergovernmental Panel on Climate Change (IPCC) are not simulating climate as it exists on Earth.  That reality of climate models will likely come as a surprise to many climate laypersons.

We presented in part 1 of this series how the spatial patterns of the modeled warming rates for the surfaces of the global oceans from 1982 to 2015 (the era of satellite-enhanced sea surface temperature observations) show no similarities to the spatial patterns of the observed (data-founded) warming and cooling.  And we discussed why it’s important that the models used by…

Michael Asten, professor of geophysics at Monash University, warns against trusting the climate models that predicted dangerous heating of the planet:

Cuts to the government-funded climate change program at the CSIRO (Commonwealth Scientific and Industrial Research Organisation) coincide with a powerful critique of climate models by John Christy in a US congressional committee hearing…

Christy, a distinguished professor of atmospheric science and the Alabama state climatologist, presented the graph reproduced here showing the remarkable failure of a set of 102 predictions via climate models, as created by groups around the world, to provide a model trend (in red) matching observed warming of the global atmosphere across the past 20 years.

Observed data from two independent datasets (weather balloons and satellites) shows a rate of warming for 1995-2015 that is a factor of 2.5 lower than the averaged predictions from those of 102 modelling groups scattered around…
