Booby is a crap Mod indeed, lets LOTS of abuse happen! Abuse is against OzPol rules.
Gotta love the chart of precipitation roach put up.
You can see the five year drought CA went through. Why did that drought happen? The Jet Stream has become wavy and the waves, the loops and ridges, move very slowly: they influence weather in locations for years at a time.
WHY is the Jet Stream weak, wavy and slow moving? AGW and the Arctic Amplification that sees the Arctic warming two, three times as fast as lower latitudes.
So roach showed that AGW is operating, not what he really wanted to show, I suppose. Dumb, uneducated people do things like that, think they are proving one thing when they are really proving the opposite
