Your assertions that they GET NOTHING is simply absurb and surreal...
Those grants require a detailed paper trail as to how they're spent, and it's very illegal for a person to pocket money themselves from a grant. If you're not just giving us yet another conspiracy theory, you should be reporting those evil scientists to the feds and getting them tossed into jail.
Most people have little idea of how grants work. They think that if Michael Mann gets a million dollar grant, it goes straight into his pocket. Nope. Grants go to institutions, not people. The institution spends it on labs, utilities, upkeep, janitor salaries, scholarships, grad student salaries, trips to Greenland, and so on. They're not allowed to give Michael Mann a bonus from it. Not a penny. Hence, nothing.
Now, any AGW scientist could instantly double their salary by switching sides and becoming a denialist. That's where the big cash is. Follow the denialist money to find the corruption. It's a credit to their integrity that most AGW scientists refuse to lie for money.
