A month or so ago an interviewer on TV asked someone, who was a proponent of the anthropogenic global warming theory, where all the snow in the northeast came from. She said something about the warming causing more moisture to be dumped into the atmosphere.
I wished that the interviewer had told her that you need cold to turn that moisture into snow. But alas, there was no such followup.
The CO2 Global Warming theory alone cannot explain snow on palm trees. We experienced that here about 2 months ago. That theory alone could explain flooded palm trees, but not snow covered palm trees. BTW - We are currently experiencing one of our worst droughts ever here in Southern California this year. Where is all that CO2 Globally Warmed rain ? We have the largest water reservoir in the world sitting right off the coast upwind from us here.
