Chief editor
The paper reveals previously-unexplored behaviours of the Earth system and illustrates how some impacts of climate change will continue to increase even after emissions become net zero. These results highlight the urgency of both achieving net zero emissions and of conducting long-term adaptation planning.

Short summary
Governments are targeting net-zero emissions later this century with the aim of limiting global warming in line with the Paris Agreement. However, few studies explore the long-term consequences of reaching net-zero emissions and the effects of a delay in reaching net-zero. We use the Australian Earth system model to examine climate evolution under net-zero emissions. We find substantial changes which differ regionally, including continued Southern Ocean warming and Antarctic sea ice reduction.
