The peer-reviewed literature indicates that for at least the last 400 years (when we have direct observations), solar irradiance has closely tracked with average global climate indicators. Duh. Earth gets nearly all of its energy from the sun.

BUT! This close tracking for hundreds of years fails starting in about 1975. For the last 35 or so years, irradiance has been declining while global average temperature has increased. This is powerful evidence for non-natural climate change.

PS
Can somebody please explain to me how I can get rich on this GW scam?
So far, I have not made a dime off of it, but if Fox is to be believed, I am missing the boat - there's a lot of money in this gig.
