Computer Models Cannot Predict Climate

Predicting climate temperatures isn’t science – it’s science fiction. Emeritus Professor of Physics at Princeton University Will Happer explains.

The following is a snippet from a large post I did for a USPS worker that wanted me to respond to the article from Time Magazine he handed over to me. My LONGER post is entitled:


Offering Critical Thinking on Global Warming


Truth be told, they have NO IDEA. Why? Because they rely on computer models, not the actual climate.

Computer Models?

Yes, most of the headlines we read are driven by computer models or cherry-picking from one data set and not taking ACTUAL temperatures into account. For instance:

See more on this @ Dr. Roy Spenser’s site. (BIO):

Roy W. Spencer received his Ph.D. in meteorology at the University of Wisconsin-Madison in 1981. Before becoming a Principal Research Scientist at the University of Alabama in Huntsville in 2001, he was a Senior Scientist for Climate Studies at NASA’s Marshall Space Flight Center, where he and Dr. John Christy received NASA’s Exceptional Scientific Achievement Medal for their global temperature monitoring work with satellites. Dr. Spencer’s work with NASA continues as the U.S. Science Team leader for the Advanced Microwave Scanning Radiometer flying on NASA’s Aqua satellite. He has provided congressional testimony several times on the subject of global warming.

Dr. Spencer’s research has been entirely supported by U.S. government agencies: NASA, NOAA, and DOE. He has never been asked by any oil company to perform any kind of service. Not even Exxon-Mobil.

(CNSNEWS) Global temperatures collected in five official databases confirm that there has been no statistically significant global warming for the past 17 years, according to Dr. John Christy, professor of atmospheric science and director of the Earth System Science Center at the University of Alabama Huntsville (UAH).

Christy’s findings are contrary to predictions made by 73 computer models cited in the United Nation’s latest Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (5AR).

Christy told CNSNews that he analyzed all 73 models used in the 5AR and not one accurately predicted that the Earth’s temperature would remain flat since Oct. 1, 1996. (See Temperatures v Predictions 1976-2013.pdf)

“I compared the models with observations in the key area – the tropics – where the climate models showed a real impact of greenhouse gases,” Christy explained. “I wanted to compare the real world temperatures with the models in a place where the impact would be very clear.” (See Tropical Mid-Troposphere Graph.pdf)

Using datasets of actual temperatures recorded by the NASA Goddard Institute for Space Studies (NASA GISS), the United Kingdom’s Hadley Centre for Climate Prediction and Research at the University of East Anglia (Hadley-CRU), the National Oceanic and Atmospheric Administration (NOAA), satellites measuring atmospheric and deep oceanic temperatures, and a remote sensor system in California, Christy found that “all show a lack of warming over the past 17 years.”

All 73 models’ predictions were on average three to four times what occurred in the real world,” Christy pointed out. “The closest was a Russian model that predicted a one-degree increase.”

German Meteorologist Says Climate Models Have Gotten 11 Of The Past 12 European Summers Wrong!

German meteorologist Dominik Jung writes at wetter.net that the first preliminary forecast for Central Europe for the upcoming summer issued by the NOAA does not look very favorable. Expect a “grisly summer”, he writes.

He writes that over the last 10 years spring has generally been on the warm and sunny side, but that Central Europeans have had to pay a price for that by having to put up with wet and variable summer weather.

Models wrong 11 out of 12 years!….

more on this later. One thing you will notice in reading the LA Times article, every pro anthropogenic [man-caused] global warming person named has a professor, or scientist in front of their name or description. Those who disagree with “man-caused” global warming are merely described as skeptics. ALTHOUGH, you at least get this:

Climate scientists, meanwhile, have had a different response. Although most view the pause as a temporary interruption in a long-term warming trend, some disagree and say it has revealed serious flaws in the deliberative processes of the IPCC.

One of the most prominent of these critics is Judith Curry, a climatologist who heads the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology. She was involved in the third IPCC assessment, which was published in 2001. But now she accuses the organization of intellectual arrogance and bias…

In case you are out of the loop, no warming has occurred in 16-years from when this article appeared in the Mail Online:

Global warming stopped 16 years ago, reveals Met Office report quietly released… and here is the chart to prove it

The figures reveal that from the beginning of 1997 until August 2012 there was no discernible rise in aggregate global temperatures

This means that the ‘pause’ in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996

The world stopped getting warmer almost 16 years ago, according to new data released last week.

The figures, which have triggered debate among climate scientists, reveal that from the beginning of 1997 until August 2012, there was no discernible rise in aggregate global temperatures.

This means that the ‘plateau’ or ‘pause’ in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996. Before that, temperatures had been stable or declining for about 40 years….

There will always be those who cannot admit the obvious, for obvious reasons (CFACT):

1. The concentration of CO2 in the global atmosphere is lower today, even including human emissions, than it has been during most of the existence of life on Earth.

2. The global climate has been much warmer than it is today during most of the existence of life on Earth. Today we are in an interglacial period of the Pleistocene Ice Age that began 2.5 million years ago and has not ended.

3. There was an Ice Age 450 million years ago when CO2 was about 10 times higher than it is today.

4. Humans evolved in the tropics near the equator. We are a tropical species and can only survive in colder climates due to fire, clothing and shelter.

5. CO2 is the most important food for all life on earth. All green plants use CO2 to produce the sugars that provide energy for their growth and our growth. Without CO2 in the atmosphere carbon-based life could never have evolved.

6. The optimum CO2 level for most plants is about 1600 parts per million, four times higher than the level today. This is why greenhouse growers purposely inject the CO2-rich exhaust from their gas and wood-fired heaters into the greenhouse, resulting in a 40-80 per cent increase in growth.

7. If human emissions of CO2 do end up causing significant warming (which is not certain) it may be possible to grow food crops in northern Canada and Russia, vast areas that are now too cold for agriculture.

8. Whether increased CO2 levels cause significant warming or not, the increased CO2 levels themselves will result in considerable increases in the growth rate of plants, including our food crops and forests.

9. There has been no further global warming for nearly 18 years during which time about 25 per cent of all the CO2 ever emitted by humans has been added to the atmosphere.

I doubt it.

Here is a Patrick Moore quote that shows how the left has politicised the issues we are dealing with above and below:

“I now find that many environmental groups have drifted into self-serving cliques with narrow vision and rigid ideology…. many environmentalists are showing signs of elitism, left-wingism, and downright eco-fascism. The once politically centrist, science-based vision of environmentalism has been largely replaced with extremist rhetoric. Science and logic have been abandoned and the movement is often used to promote other causes such as class struggle and anti-corporatism. The public is left trying to figure out what is reasonable and what is not.”
