Back in 2014, Crikey published a piece by Clive Hamilton on the 12 people doing the most to block action on climate change in Australia, including Ian Plimer. Hamilton included this paragraph on Plimer's book How to Get Expelled From School:

"Plimer’s 2011 book -- How to Get Expelled From School (launched by John Howard and mailed by the IPA to hundreds of schools) -- listed 101 questions for sceptical students to ask their “warmist” teachers, i.e. those who respect science. The federal Department of Climate Change (abolished by Abbott) prepared a response that thoroughly debunked his claims in words a child can understand. How long before Environment Minister Greg Hunt is instructed to have this demolition of Plimer taken down?"
