One of Australia’s leading climate change experts says Queensland's recent extreme weather events show the state is experiencing climate change, and warns both the state and federal governments are not keeping pace with the changes.

Professor Ian Lowe, a member of the Queensland governments senior climate change body, claims you have to be in deep denial not to accept there are unmistakable signs of climate change, and there is no sense of urgency to mitigate these changes.

Prime Minister Scott Morrison declined to comment on whether the torrential Townsville rain was the result of climate change, instead offering his support to those flood affected.
