Any leftie who makes snarky cracks about science had best not parrot the "anthropogenic CO2 causes big storms" meme. It's totally contrary to science. To the extent CO2-induced warming has any effect, it would REDUCE the # & severity of storms. The IPCC knows that & admits it when pressed. You don't hear actual credentialed activists like Jones, Hansen, or Mann spouting this drivel. Even Al gore is pretty circumspect about it.
