That conclusion is now being challenged by new data and the failure of old data to predict what has actually happened to the climate since 2001."
Global warming challenged by new data and failed predictions
Here's the report. I hope you like math!
Discussion
"We have set out and then critically examined a detailed account of the IPCC’s method of evaluating climate sensitivity. We have made explicit the identities, interrelations, and values of the key variables, many of which the IPCC does not explicitly describe or quantify. The IPCC’s method does not provide a secure basis for policy-relevant conclusions. We now summarize some of its defects."
(Too many to list, read the report)
Conclusion
"Even if temperature had risen above natural variability, the recent solar Grand Maximum may have been chiefly responsible. Even if the sun were not chiefly to blame for the past half-century’s warming, the IPCC has not demonstrated that, since CO2 occupies only one-ten-thousandth part more of the atmosphere that it did in 1750, it has contributed more than a small fraction of the warming." (+ much more)

Have you ever noticed that when a denialist story breaks, one of the most salient aspects is it's lack of truth.
In actual fact, the APS (representing 50,000 physicists), as they have seen fit to mention on the front page of
their website, is unchanged:
APS Climate Change Statement
APS Position Remains Unchanged
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."
An article at odds with this statement recently appeared in an online newsletter of the APS Forum on Physics and Society, one of 39 units of APS. The header of this newsletter carries the statement that "Opinions expressed are those of the authors alone and do not necessarily reflect the views of the APS or of the Forum." This newsletter is not a journal of the APS and it is not peer reviewed.
For context, this keeps them in line with these other scientific organisations that agree with the basics of anthropogenic global warming:
Intergovernmental Panel on Climate Change (IPCC) 2007
InterAcademy Council
Joint science academies' statement 2008
Joint science academies’ statement 2007
Joint science academies’ statement 2005
Joint science academies’ statement 2001
International Council of Academies of Engineering and Technological Sciences
European Academy of Sciences and Arts
Network of African Science Academies
National Research Council (US)
European Science Foundation
American Association for the Advancement of Science
Federation of American Scientists
World Meteorological Organization
American Meteorological Society
Royal Meteorological Society (UK)
Australian Meteorological and Oceanographic Society
Canadian Meteorological and Oceanographic Society
Canadian Foundation for Climate and Atmospheric Sciences
International Union for Quaternary Research
American Quaternary Association
Stratigraphy Commission of the Geological Society of London
International Union of Geodesy and Geophysics
International Union of Geological Sciences

Canadian Federation of Earth Sciences
Geological Society of America
American Geophysical Union
American Astronomical Society
American Institute of Physics
American Chemical Society
Engineers Australia (The Institution of Engineers Australia)
Federal Climate Change Science Program (US)
American Statistical Association
Whereas these scientific organisations back the denialists:
With the July 2007 release of the revised statement by the American Association of Petroleum Geologists, no remaining scientific body of national or international standing is known to reject the basic findings of human influence on recent climate.
Similarly, the paper you mention, by Viscount Monckton of Brenchley, represents the views of 0 physicists, and one journalist/politician.
