In my view, the IPCC and their public relations people have created a trust issue. One reason is that the release of their 2007 summary was accompanied by a press release claiming that the report was the product of “The world's leading climate scientists.” Who made these people the worlds leading climate scientists? The press release.
Another example of this trust problem is demonstrated in the IPCC graph below. This graph was released with the IPCC’s 2007 summary that concluded that they are 90% certain that man made CO2 is responsible for much of 20th century warming. This graph [below] is based on their radiative heat transer theory. It attempts to demonstrate how much each radiative forcing component has contributed to global warming. Now look at the column on the far right labeled “LOSU.” This is the Level Of Scientific Understanding for each component.
Notice how most components have a medium or low level of understanding. Does this make you think that they are 90% certain of their conclusion?
Now look at the last component of the climate system, solar forcing. Notice that it comes with a “low” Level Of Understanding. What bothers me is that the IPCC completely ignores the scientific understanding, studies and experiments related to the effect of galactic cosmic rays on cloud cover, such warming effect almost completely negates any warming that the IPCC theorizes is created by man made greenhouse gasses. “The 2% change in low clouds during a solar cycle will vary the input of heat to the Earth’s surface by an average of about 1.2 Wm squared, which is not trivial. It can be compared, for example, with 1.4 Wm squared attributed by the Intergovernmental Panel On Climate Change for the greenhouse effect of all of the additional carbon dioxide in the air since the Industrial Revolution.” (C5)Visit Kristen's award-winning site here: Ponder the Maunder.
