So many do - though in this case there may be some justification.
I admit to not reading past the point where I realised they were applying a pure statistical method to climate change. Whilst you can say the odds of a coin-toss coming up heads 10 times in a row is about 1000/1 (i.e. 99.9% improbable), the climate is a tad more complex. So though we can prove that CO2 is a greenhouse gas, and can prove that human activity is generating CO2, and prove that CO2 levels in the atmosphere are increasing rapidly, and prove that since the industrial revolution the average global temparature has been rising ...... you can't absolutely prove that this means AGW must be true. That is why the IPCC says that the probability lies between 95-100%. I think that is in "beyond reasonable doubt" territory, yet some on this forum insist the polluters are "not guilty". I don't understand that.
Unfortunately, the 99% probability level has been DISPROVED.
Also at the 95% probability level.
Both of these were in the initial papers cited by IPCC #4.
The WSJ has a good story on it. Note in response to the frequent claims about China being a GW champion - they are voting with their lack of feet. See below.

[h=1]Whatever Happened to Global Warming?[/h] [h=2]Now come climate scientists' implausible explanations for why the 'hiatus' has passed the 15-year mark.[/h]

On Sept. 23 the United Nations will host a party for world leaders in New York to pledge urgent action against climate change.
Yet leaders from China, India and Germany have already announced that they won't attend the summit and others are likely to follow, leaving President Obama looking a bit lonely. Could it be that they no longer regard it as an urgent threat that some time later in this century the air may get a bit warmer?
In effect, this is all that's left of the global-warming emergency the U.N. declared in its first report on the subject in 1990. The U.N. no longer claims that there will be dangerous or rapid climate change in the next two decades. Last September, between the second and final draft of its fifth assessment report, the U.N.'s Intergovernmental Panel on Climate Change quietly
downgraded the warming it expected in the 30 years following 1995, to about 0.5 degrees Celsius from 0.7 (or, in Fahrenheit, to about 0.9 degrees, from 1.3).
Even that is likely to be too high. The climate-research establishment has finally admitted openly what skeptic scientists have been saying for nearly a decade: Global warming has stopped since shortly before this century began.
First the climate-research establishment
denied that a pause existed,
noting that if there was a pause, it would invalidate their theories. Now they say there is a pause (or "hiatus"), but that it doesn't after all invalidate their theories.
Alas, their explanations have made their predicament worse by implying that man-made climate change is so slow and tentative that it can be easily overwhelmed by natural variation in temperature—a possibility that they had previously all but ruled out.
...
If the pause lasted 15 years, they conceded, then it would be so significant that it would invalidate the climate-change models upon which policy was being built. A
report from the National Oceanic and Atmospheric Administration (NOAA) written in 2008 made this clear: "The simulations rule out (at the 95% level) zero trends for intervals of 15 yr or more."
Well, the pause has now lasted for 16, 19 or 26 years—depending on whether you choose the surface temperature record or one of two satellite records of the lower atmosphere. That's according to a new statistical
calculation by Ross McKitrick, a professor of economics at the University of Guelph in Canada.
It has been roughly
two decades since there was a trend in temperature significantly different from zero.
The burst of warming that preceded the millennium lasted about 20 years and
was preceded by 30 years of slight cooling after 1940.
The warming in the last three decades of the 20th century, to quote the
news release that accompanied their paper, "was roughly half due to global warming and half to the natural Atlantic Ocean cycle." In other words, even the modest warming in the 1980s and 1990s—which never achieved the 0.3 degrees Celsius per decade necessary to satisfy the feedback-enhanced models that predict about three degrees of warming by the end of the century—had been exaggerated by natural causes. The man-made warming of the past 20 years has been so feeble that a shifting current in one ocean was enough to wipe it out altogether.
Putting the icing on the cake of good news, Xianyao Chen and Ka-Kit Tung think the Atlantic Ocean may continue to prevent any warming for the next two decades. So in their quest to explain the pause, scientists have made the future sound even less alarming than before.
