Nationally syndicated radio host Hartmann debated with CFACT Climate Skeptic Paul Driessen on September 21, 2015. The heading on Hartmann's website is 'Climate Change Deniers Should Be In Prison'

Hartmann to Driessen: 'You are paid to lie to people.' 'Why should you NOT be in jail?'

'I am talking about racketeering, organized crime. I am calling you a criminal.'

Driessen talks of why he is skeptical and Hartmann responds: 'That's what you should be in jail for' - 'You are killing people.' - 'You have five million climate refugees.'

'Dead children -- you're responsibility.' - 'It's all the consequence of climate change.'
