True, but determining the actual facts seems to be an issue...
The Climate Crisis Hoax being just one article discussing the the topic of AGW fraud...
...Other fraud is evident through public exposure of e-mail files retrieved from the Climate Research Unit (CRU) at Britain’s University of East Anglia. Scandalous exchanges among prominent researchers who have fomented global warming hysteria confirm long-standing and broadly suspected manipulations of climate data. The communications also reveal conspiracies to falsify and withhold information, to suppress contrary findings in scholarly publications, and to exaggerate the existence and threats of man-made global warming. Many of these individuals have had major influence over summary report findings issued by the IPCC. Still other evidence comes from mouths of government officials, international climate summit organizers and leading science spokespeople recorded in candid public admissions.
Another lie claims that there is a consensus among climate scientists that a known man-made global warming crisis exists. Official statements to the contrary presented by more than 650 international climate-related experts who presented contrary official testimony recorded in a 2008 U.S. Senate minority report suggest otherwise. So do petitions signed by more than 30,000 scientists that have challenged IPCC’s 1995 procedures and report representations. Those circumstances prompted Dr. Frederick Seitz, former president of the U.S. Academy of Sciences, the American Physical Society, and Rockefeller University to write in The Wall Street Journal: “I have never witnessed a more disturbing corruption of the peer review process than events that led to this IPCC report.” ...
So apparently a number of folks in the global warming community feel that they
are entitled to their own facts. Even if AGW is real, the fraud at the center of the studies taints the conclusions.
