If anything happens in the world, you know the standard explanation. Like I've said, it used to be 'God's Will' and now it's 'climate change'. Neat.
ps. we do have a mechanism that was discovered before nasa shut down all atmospheric physics. It's large clear-air convection cells. The cold air comes down in very dense sheets. If they had continued these studies we would have a cheap and easy laser to deal with this stuff. It was bad in the 70's and now will get worse for our ice cycle. One of the many consequences of giving up on physics.
