Monckton: IPCC climate models speeding out of control compared to real world

Christopher Monckton reminds us of just how badly the “experts” have failed in the last 15 years, even including the recent hottest ever El Nino months. China bombed the atmosphere with record carbon “pollution” — worse than we thought. The world though, warms sedately at a mere half a degree per century. This is what 95% certainty looks like.   — Jo

Introducing the global warming speedometer

A single devastating graph shows climate panic was unfounded

By Christopher Monckton of Brenchley

A single devastating graph – the new global warming speedometer – shows just how badly the model-based predictions made by the Intergovernmental Panel on Climate Change have failed.

Has the world started cooling? Hints from 4 of 5 global temperature sets…

I’m not keen on short term trends at all, they have a habit of flicking in and out of statistical significance with each month’s new data, or even switching from cooling to warming. But for what it’s worth, and only time will tell, perhaps the world entered the downswing of the PDO cycle in temperatures circa 2005.

If the world was entering a gently cooling phase, this is what it would look like

Syun Akasofu pointed out that there was a simple 60 year oscillation of global temperatures (about 30 years of warming, about 30 years of mild cooling) on top of a long slow rise that started more than 200 years ago. He predicted that we were at the top of one of the cycles, and were about to see the beginning of a cooler cycle. This early data suggests he may be right.

The cooling for the last eight years is statistically significant in 4 of the 5 major air temperature datasets. One, UAH, shows a small (statistically insignificant) rise since 2005.

And here’s the political point: how many of [...]
