In an incident that has got Australia talking, Senator Jim Molan was booed while speaking on a panel TV discussion on the bushfire crisis.

The politician, from the governing Liberal Party, was talking about climate change on ABC's Q&A programme, and cast doubt on whether it was caused by human activity.

Mr Molan said he wasn't "relying on science" for his views, and defended the government's climate change policy.

Government critics say human-induced climate change has been a major contributing factor to the bushfires, and that action must be taken to address rising global temperatures.
