LEVELS of atmospheric carbon dioxide have been steadily rising, but since about 1998 global warming has stalled.   Some climate scientists claim the reason has everything to do with the sun. 

A little over a month ago a planning meeting was called to discuss whether more research should be undertaken by the US National Academy of Sciences/US National Research Council in particular to consider the role of solar forcing on climate.  

Well known meteorologist and blogger Roger Pielke (Sr) was at the meeting and claims that compelling evidence was present showing that current climate models do not adequately represent the solar influence on climate.

HOW many times have you heard or read words to the effect that 4000 scientists from the Intergovernmental Panel on Climate change (IPCC) supported the claims about a significant human influence on climate? I think I’ve seen it on television, radio and the Internet and I know that politicians at national levels have quoted such figures. There’s no question whatsoever. It’s utterly wrong.

In fact, once the duplicated names are removed that number falls below 2,900 and if we only want those who explicitly supported the claims it falls to only about 60. So how does 4,000 become 60? Let’s take a closer look at the real numbers.

Consider the statement “The IPCC report concluded that there is a human influence on climate. This was supported by almost 4,000 authors and reviewers.” The popular mythology – and one that IPCC never tries to correct – is that those 4,000 supported the findings but all they really supported, by their work, was the creation of the report. The IPCC is allowing, or perhaps even encouraging, an ambiguity be misinterpreted, and not for the first time either, but I digress.

But how many individuals were involved? Was it 4,000 or some other number?
