The guy that started the weather channel is calling global warming a hoax. Part of this hoax (Weather channel guy made this claim) involves shutting down 1000's of weather monitoring stations with cooler average temperatures. This results in a statistically manipulated rise in the average global temperature.
How do we make this info mainstream?
They need data to prove their theory. They (NASA) got caught lying by falsifying data before, so now instead of cherry picking data which is too obvious, they cherry pick their data sites which is slightly more difficult to catch.
