Ah heck, I will answer my own question.
The following societies acknowledge the phenomenon of global climate change, and the fact that human activities play some role, but are equivocal on the importance of that role.
American Association of State Climatologists
National Science Foundation
National Snow and Ice Data Center
American Geological Institute
American Institute of Professional Geologists
Polish Academy of Science Geological Committee
Canadian Federation of Earth Sciences
American Association Of Petroleum Geologists (1)
(1) AAPG was the lone "denier" organization until they formally revised their position in July 2007 to be neutral. Now there is not a single scientific organization or society that denies global climate change with some level of human influence.
