In the discussion I referred to the scientific consensus on climate change. A survey of 928 peer-reviewed abstracts on the subject 'global climate change' published between 1993 and 2003 shows that not a single paper rejected the consensus position that global warming is man caused. Another study of over 12,000 peer-reviewed abstracts on the subjects of 'global warming' and 'global climate change' published between 1991 and 2011 found that of the papers taking a position on the cause of global warming, over 97% agreed that humans are causing it.
Paul said during the interview that while carbon dioxide traps heat in the atmosphere, the effect was limited, so adding more carbon dioxide would not increase the warming effect, because it already saturates the atmosphere. This claim is discussed here.
The Dunning–Kruger effect is a cognitive bias which makes less skilled people overestimate their skills, partly because they lack the skill to judge their own skills.
