Climate Science vs Politics: The Road Ahead

[Geee]

American Thinker:

There is good news and bad news about climate. The good news is that science evidence has made it quite clear that the human contribution to a possible global warming is minor; in fact it cannot even be identified in the data record. The bad news is that the media and politicians pay no attention whatsoever to the science and are marching ahead full-speed with efforts to control CO2 emissions -- thereby hurting the economy, destroying jobs, and stunting economic growth. They are under the illusion that there is a nearly complete scientific consensus in support of catastrophic anthropogenic global warming (CAGW).

First, the good news

As one of the many official "expert reviewers" of the UN-IPCC (Intergovernmental Panel on Climate Change), I have had a chance to examine the so-called evidence to back up the IPCC conclusion (with claimed >95% certainty!!) that a reported global warming of the 1980s and 1990s is anthropogenic and that models can be used to predict a future temperature increase of around 2-3 degrees by 2100. I found that IPCC uses the same flimsy evidence in its fifth assessment report (AR5), due in 2013, as they did in AR4 (Assessment Report #4, published in 2007); except that there they only claimed 90% certainty.
