Today the Minister for Climate Change and Energy Efficiency accused me of misleading the House by saying that global average temperatures had not increased in 10 years. I suggest the minister go to the data on global average temperatures with the Hadley Centre and do a linear regression. Further, Professor Will Steffen, the government's own climate change adviser, in an interview with Andrew Bolt repeatedly refused to contradict Bolt's statement that the globe had not warmed in 10 years, despite being invited to do so.
