Breitbart (among others) writes that the United Nations climate panel's report may not be as objective as they want us to believe.
"An exhaustive United Nations report that claimed with 95% certainty that humans are responsible for global warming left out data that found the planet has stopped warming over the last 15 years, because it did not fit with the climate change agenda it wanted to advance."
An earlier draft of the United Nations report, which was not used, acknowledged its climate models “do not generally reproduce the observed reduction in surface warming trend over the last 10–15 years.” In other words, reality slapped their predictions in the face and took its lunch money.
As the UK's Sun News says, "The issue is important because if the Earth is not warming as greenhouse gas emissions rise, it strikes at the heart of the theory of man-made global warming and suggests natural factors may be the greatest influence on climate."
Often global warming alarmists will argue as though the science on manmade global warming is settled, that a mere handful of kooks disagree with their conclusion, and that few, if any, reputable scientists disagree with it. The editor of "Physics and Society," a publication of the American Physics Society, wrote these words:
There is a considerable presence in the scientific community of people who do not agree with the IPCC (United Nations Intergovernmental Panel on Climate Change) that anthropogenic CO2 emissions are very probably likely to be primarily responsible for the global warming that has occurred since the Industrial Revolution.
Global warming* alarmists are like those "true believers" who honestly think that psychic star Uri Geller has real powers, despite the fact that a) He has repeatedly failed to prove his powers under strictly controlled conditions, and b) He has been caught cheating. Their desire to believe overrides any common sense.
Global Warming Charlatanism
Misrepresentation of findings. Christopher Landsea of the Atlantic Oceanographic & Meteorological Laboratory was a contributing author for the UN's second International Panel on Climate Change in 1995, writing the sections on observed changes in tropical cyclones around the world.
He contributed again to the "Third Assessment Report" in 2001. And he was invited to contribute to the IPCC's "Fourth Assessment Report." This report would specifically focus on Atlantic hurricanes, Landsea's specialty, and be published by the IPCC in 2007.
In October, 2004, the IPCC's Kevin Trenberth -- the very person who had 
invited Landsea's contribution -- was to participate in a press conference. The title of the press conference was "Experts to warn global warming likely to continue spurring more outbreaks of intense hurricane activity." None of Landsea's work substantiated this claim. Nobody's had.
Landsea tried to contact Trenberth to clarify the scientific truth: No proven correlation between hurricanes and global warming. To Landsea's dismay, the press conference proceded, with the media drooling over the flashy headline possibilities.
Landsea resigned from the IPCC's report, in protest over the politicization and misrepresentation of scientific findings. You can read his story in his own words in his "Open Letter to the [Scientific] Community." Unfortunately, other scientists, eager for social status and funding, stepped in to support the bogus claims made by politicians.
The Big Question
How valid is the global warming alarmists' argument if they have to misrepresent and lie to achieve their goals?
* "global warming" in these discussions is defined as "man-made catastrophic climate change."
