There’s no grant money to be had if you admit Global Warming is a hoax.
In a nutshell...that the root of much of it.
There are ideologues who believe it root and branch, too...and getting grants is a nice byproduct for them.
But scientists who see it for the hooey it is are attacked and driven out of the educational bastions that are fostering that crap.
So, most of them who disagree with it simply shut up to save their jobs.
A GREAT book that discusses this aspect a little bit is “Red Hot Lies: How Global Warming Alarmists Use Threats, Fraud, and Deception to Keep You Misinformed” by Christopher Horner.
Not just the money...it’s the ease of data generation that draws so many in.
Lazy scientists can pick and choose data to come to a conclusion that is stated openly in the government grant because the grant application says the conclusion will be reached with the proper amount of money.
If the government changed to paying people to find there is no warming, what would happen to the results from all these “climate scientists”?
