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
Climate Change: Vital Signs of the Planet: Scientific Consensus
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 – 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.
Quantifying the consensus on anthropogenic global warming in the scientific literature – IOPscience
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.
