Sometimes, LaRouche's people get things right on. Sometimes, they are way, way off, such as with this case of Piers Corbyn. Piers Corbyn may have some decent instincts ideologically, but he's all but mindless when it comes to the subject of Anthropogenic Global Warming.
Consider the following:
"CO2 has never driven, does not drive and never will drive weather or climate. Global warming is over and it never was anything to do with CO2. CO2 is still rising but the world is now cooling and will continue to do so."
That's Piers Corbyn.
Honestly, has the world been cooling since 2008? Hardly!
