It is a great disappointment that numerous Climate Change Authority discussions and documents on the issue of climate change have failed to emphasise its impact on health. To avoid widespread, severe and irreversible impacts associated with present trajectory of 4 degrees of global warming, urgent action must be taken to reduce greenhouse gas emissions. The response of Government thus far has been grossly inadequate – and that Australia needs to commit to a reduction target on 2020 levels of at least 40% by 2025 and a reduction of at least 95% by 2050. This is the only way that we might be able to confine global temperature rise to 2°C and thus avoid severe consequences to human health. The time to act is now.
