It has been done before...on larger scales, by far more important people than climate scientists. Believe it or not, there are actual conspiracies...Here are a few....feel free to look them up...much has been written on them over the years.
The Dreyfus Affair, The Mafia (they were practically unknown til the 60's), MK-Ultra a CIA program that used LSD on unsuspecting test subjects, Operation Mockingbird - CIA payments to high profile journalists and publishers to publish CIA propaganda, Aesbestos - between 1930 and 1960 manufacturers did all they could to prevent knowledge of the dangers of the product from leaking out, Watergate, The Tuskegee Syphillis Study, Operation Northwoods, Counter Intelligence programs against activists in the 60's, The Iran Contra Affair, CIA Drug Running in LA.
Conspiracies do happen...and they happen at the highest levels. I think climate science is the victim of an error cascade, but you claim absolute knowledge that it isn't conspiracy. That is a claim you can't support.
The burden of providing evidence is on you. You have charged the scientific community at large with conspiring to deceive the public and you seem to have no evidence of that at all. Irony...
I have done no such thing...I have said that there is no observed, measured evidence which supports the claim that the climate we are experiencing is anything other than natural.
