Make of THIS what you will.
But bear in mind these two important factors:
1) The following organizations subscribe to mainstream scientific theories on man-made global warming:
American Association for the Advancement of Science, American Astronomical Society, American Chemical Society, American Geophysical Union, American Institute of Physics, American Meteorological Society, American Physical Society, American Quaternary Association, Australian Meteorological and Oceanographic Society, Canadian Foundation for Climate and Atmospheric Sciences, Canadian Meteorological and Oceanographic Society, European Academy of Sciences and Arts, European Geosciences Union, European Science Foundation, Geological Society of America, Geological Society of London-Stratigraphy Commission, InterAcademy Council, International Council of Academies of Engineering and Technological Sciences, International Union of Geodesy and Geophysics, International Union for Quaternary Research, National Research Council, Network of African Science Academies, Royal Meteorological Society and World Meteorological Organization.
2) There is not even one reputable scientific organization that has maintained a dissenting opinion regarding man-made global warming. Not even one.
The last such organization to do so was the American Association of Petroleum Geologists, which eventually backed away from its 1999 statement rejecting the likelihood of human influence on recent climate change.
