97% of climate models say that 97% of climate scientists are wrong. Yet we base, literally, trillions of dollars of other people’s (taxpayers) money on alarmist climate change policy, schemes and rent-seeking scams (windmills/solar) on overheated, predictive models that do not observe climate reality.
CMIP5 IPCC climate models don’t even ‘model’ clouds, the sun or ocean currents (AMO/PDO).
What possibly could go wrong? /sarc.
RCP8.5 BS in = Alarmist BS out.
It’s no wonder ‘Climate models don’t work’!
Guest essay by Larry Hamlin
In February 2016 climate scientist Dr. John Christy presented testimony to Congress demonstrating that climate models grossly exaggerate and over estimate the impact of atmospheric CO2 levels on global temperatures . Dr. Christy noted in his testimony that “models over-warm the tropical atmosphere by a factor of approximately 3″.
NOAA climate activist scientist Dr. Gavin Schmidt challenged Dr. Christy’s work claiming that it was “partisan” and using vague statistical arguments claimed that Christy’s work improperly presented the performance of climate models. These claims by government scientist Dr. Schmidt peaked the interest of statistics expert Steven McIntyre who was one of the most prominent experts to expose the flawed science (proxy shenanigans) and mathematics (statistical errors) behind the now disgraced thousand year long global temperature profile infamously known as the “hockey stick” (https://climateaudit.files.wordpress.com/2005/09/ohioshort.pdf).
Mr. McIntyre conducted a review of Dr. Schmidt’s claims (https://climateaudit.org/2016/05/05/schmidts-histogram-diagram-doesnt-refute-christy

A single devastating graph shows official climate predictions were wild
By Christopher Monckton of Brenchley
The new global warming speedometer shows in a single telling graph just how badly the model-based predictions made by the Intergovernmental Panel on Climate Change have over-predicted global warming.
The speedometer for the 15 years 4 months January 2001 to April 2016 shows the [1.1, 4.2] C°/century-equivalent interval of global warming rates (red/orange) that IPCC’s 1990, 1995 and 2001 reports predicted should be occurring by now, compared with real-world, observed warming (green) equivalent to less than 0.5 C°/century over the period.
RSS and UAH monthly near-global satellite lower-troposphere temperature anomaly values for each month from January 2001 to April 2016 were assumed to be broadly accurate and were averaged. The least-squares linear-regression trend on their mean was determined and found equivalent to 0.47 C°/century.
Predictions in IPCC’s Assessment Reports
IPCC (2007, 2013) are…
