The primary tool of global warming alarmists is claiming that 97% of scientists agree with them. They normally cite this NASA web page which says:
97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are extremely likely due to human activities
If you actually click on the reference, you quickly realize that the claim is fraudulent. NASA used a small subset of papers which actually make attribution. (The only people who have any reason to make attribution are climate alarmists.)
Among papers expressing a position on AGW, an overwhelming percentage (97.2% based on self-ratings, 97.1% based on abstract ratings) endorses the scientific consensus on AGW
Two-thirds of the papers they reviewed took no position, so they threw them out. But then comes the really big lie ‚Äì with the one-third of remaining papers, they conflated “humans are causing global warming” with “Climate-warming trends over the past century are extremely likely due to human activities”
We find that 66.4% of abstracts expressed no position on AGW, 32.6% endorsed AGW, 0.7% rejected AGW and 0.3% were uncertain about the cause of global warming. Among abstracts expressing a position on AGW, 97.1% endorsed the consensus position that humans are causing global warming.
Everyone agrees that humans have caused some warming. That is a far cry from saying humans caused all of the claimed warming. Only 52% of professional members of the American Meteorological Society believe humans are primarily responsible for global warming. Thirty-seven percent of professional forecasters believe that, and seventy-eight percent of publishing climate scientists.
No group comes close to 97%. As is normally the case with NASA climate science, they are committing fraud. there is no 97% consensus.
