Australia’s latest climate change statement shows we have little hope of reaching net zero emissions by 2050. There’s good news on the 2030 target, but then what? John Quiggin, Professor, School of Economics, The University of Queensland Licensed as Creative Commons – attribution, no derivatives.

For the proposed Great Koala National Park to actually help koalas, logging should stop and plantations should be added to the park.

Nations struggle if the health of their population fails. But good health is seriously threatened by climate change. So putting health at the centre of climate action makes sense.
