Tony Abbott has argued that the planet's warming climate is “probably doing good, or at least, more good than harm", telling a gathering of climate sceptics in the UK that more people die in cold snaps than in heat waves. In a speech due to be delivered today and telegraphed in The Australian, the former prime minister says there "must not be" a Clean Energy Target (CET) introduced in Australia and warns: "Beware the pronouncement, 'the science is settled'."

The speech also argues that photographs of Manly beach taken over the last 100 years do not reveal any signs of a sea rise.
