East Bumcrack University 

A marginal research university that publishes man-made climate change denial research that is unsupported by mainstream institutions.

First used by Australian journalist Annabel Crabb on ABC's "Insiders" program in response to climate skeptic Andrew Bolt. Quoted in Hansard minutes of Australian Senate, Nov 2009.

That sounds like another factoid you picked from East Bumcrack University to support your climate change skeptic arguments
