Significant work that contradicts the claims of the UN Intergovernmental Panel on Climate Change (IPCC)

Hollow Models? 
The long writing career of British logician and philosopher Bertrand Russell covered a period of marked change in science. The term natural philosophy was giving way to the term physical science and extensive divisions were occurring into branches such as physics, chemistry, etc. Already, it had been shown that long-held beliefs needed continuing empirical verification. For example, European philosophers long held the view that knowledge can be logically deduced from generally held beliefs, or propositions, such as: all swans are white; if it is a swan, it is white. This logical view was broken when the premise was falsified with the discovery of black swans in Australia in 1697. The occurrence has been used to demonstrate that logic alone is not sufficient to demonstrate a proposition has meaning in the physical world (truth). [Stock market investor Nassim Nicholas Taleb developed an investment (speculation) strategy based on unlikely events, which has different meaning.]

Previously, it was held that mathematics, the language of science, conveys empirical meaning. Euclidian geometry fit well with Newtonian Mechanics. However, Brownian Motion, discovered in 1827, did not. Further, Quantum Mechanics, advanced at the beginning of the 20th century by Max Planck, Einstein, and others, does not fit into a Euclidian scheme. Mathematics alone is not sufficient to advance knowledge, meaning, of the physical world. Empirical verification is necessary.

Recently, we have seen significant work that contradicts the claims of the UN Intergovernmental Panel on Climate Change (IPCC), and others, that carbon dioxide is causing dangerous global warming. As John Christy, Roy Spencer, and others with the Earth System Science Center at the University of Alabama in Huntsville have published, the bulk atmosphere is not warming as projected by a multitude of models used by the IPCC. Using the Canadian Climate Model Run 3, as an example, they show that the incorrectly termed “distinct human fingerprint”, the tropical “hot spot” between about 20ºN and 20ºS, does not exist in 38 years of atmospheric temperature data.

In its latest Assessment Report (AR5, 2013 & 2014), the IPCC no longer claims a tropical hot spot, but such a condition is necessary if water vapor is to amplify the slight warming produced by an increase in carbon dioxide (CO2) shown in laboratory experiments, as speculated in the 1979 Charney Report, published by the National Academy of Sciences. Thus, the IPCC and its followers such as the US Global Change Research Program (USGCRP), with 13 US government participating agencies, are in a difficult situation. They have no empirical basis for declaring that greenhouse gases, particularly CO2, are causing dangerous global warming.

Over one hundred years ago, it was shown that mathematics and logic, alone, are not sufficient for establishing meaningful knowledge about the physical world. Reliance on mathematical models, without empirical verification, is an empty science. The global climate models being used are hollow.
