It does not look like Michael Mann has been on the Weather Channel recently, but Accuweather had him on here - http://www.accuweather.com/en/weather-blogs/climatechange/climate-extremes-what-climate-says-about-sandy/2620302.
They don’t need Mann. All their on camera peeps are touting GW every chance they get per the script.
The whole hype machine of “naming” winter storms like hurricanes is intended to convince uncritical minds that the weather is “more catastrophic than ever” due to GW.
