Mutiny at the American Physical Society (APS)! Although the society (in this case physical refers to physics) has accepted the notion that man-made gases are affecting our climate, some of their member aren't buying it. The following article excerpted from the APS Physics site uses extensive analysis to show that the models used to prove global warming are flawed and in fact exaggerate the affect of CO2 as much as 500 to 1000%, there has been no warming since 1998 and in fact a cooling trend is indicated for the last six years

Here's an excerpt:

Climate Sensitivity Reconsidered

The following article has not undergone any scientific peer review, since that is not normal procedure for American Physical Society newsletters. The American Physical Society reaffirms the following position on climate change, adopted by its governing body, the APS Council, on November 18, 2007: "Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth's climate."

By Christopher Monckton of Brenchley


The Intergovernmental Panel on Climate Change (IPCC, 2007) concluded that anthropogenic CO2 emissions probably caused more than half of the “global warming” of the past 50 years and would cause further rapid warming. However, global mean surface temperature has not risen since 1998 and may have fallen since late 2001. The present analysis suggests that the failure of the IPCC’s models to predict this and many other climatic phenomena arises from defects in its evaluation of the three factors whose product is climate sensitivity:

  1. Radiative forcing ΔF;
  2. The no-feedbacks climate sensitivity parameter κ; and
  3. The feedback multiplier ƒ.

Some reasons why the IPCC’s estimates may be excessive and unsafe are explained. More importantly, the conclusion is that, perhaps, there is no “climate crisis”, and that currently-fashionable efforts by governments to reduce anthropogenic CO2 emissions are pointless, may be ill-conceived, and could even be harmful.

Warning! There's a lot of math, this is not light reading!
