Is man-made global warming occurring? Despite what you may read or hear from the media, man-made global warming has not been established beyond a reasonable doubt. Here are five big reasons why:
1. Many experienced and credible scientists with good character do not believe that man-made global warming has been proved.
2. Proponents of man-made global warming claim that warming is a fact because of “consensus”; i.e they say that a majority of scientists agree that man-made global warming is happening. But consensus is a logical fallacy, and a sign of junk science. There have been numerous instances where a minority of scientists have ultimately been proven correct, regardless of the prevailing consensus of the day. Science is based on fact, not on a vote of scientists.
3. Proponents of man-made global warming, if they truly believed in their research and analysis, would welcome the views of skeptics, because only by such challenges does science eventually converge on the truth. Instead, many proponents of man-made global warming do not welcome criticism or skeptical inquiry, and instead wage personal attacks on the skeptics. (Personal attacks are an example of the “ad hominem” logical fallacy.)
4. Proponents of man-made global warming base their beliefs on data that cannot be replicated by other scientists.
5. Proponents of man-made global warming are continually adjusting the “models” they previously created and used for predicting today’s weather, when today’s weather is not what was predicted by their earlier models. And rather than admit failure, the proponents try to obscure that fact by making up excuses and continually tinkering with their models.
A couple of interesting and thorough overviews of the junk science underlying the proponents of global warming can be found here (both by Robert Wagner):

“Climate ‘Science’ Bombshell May Be Getting Ready To Burst”
The following recent article is also of interest:
“The game is up for climate change believers” by Charles Moore.
(Be sure to check the comments at the end of the article by Exton, “Word of the Environmentalist.”)
p.s. I’m finding less time to compose in-depth posts, so am trying to provide brief updates of interesting news bites through twitter, which you can follow here: http://twitter.com/engthinking

The media are complicit with the scientists in covering the issue. It’s routine to incorrectly describe the consensus claims to make them appear more credible, though perhaps that’s explained most simply by the credulity of the media.
I put together a summary of the studies cited to show a climate change consensus.

Yes, I was visiting looking to see if you’ve got anything more about PolitiFact. I’ll be back later.
