This is a belting example. An Australian Senator stands up in the Australian Senate and, very confidently, talks absolute bollocks intended to show that carbon dioxide isn't actually a greenhouse gas.
The Dutch government has taken up the sword somewhat toward science denial. For instance, in my country I see this video with a 'label' in climate change with some factual info.
Pedantic or belittling? No, I think in a time where so many are misled so easily, it is a tool, if usd proportionally, that should be allowed.
