Climate change has been described as the biggest global health threat of the 21st century, while the response to climate change provides the greatest opportunity to protect health. The scientific evidence for climate change is unequivocal, and the magnitude of the consequences can no longer be ignored. Evidence clearly shows that we will be seeing further rising temperatures and sea levels, and more frequent and intense extreme weather events such as heavy rains, heat waves, cyclones, droughts and floods.
Some regions are more vulnerable to climate change, such as South Asia and the Pacific region, the Middle East, the Sahelian Belt, Southern Africa and Central America. In Australia, we have already witnessed an unprecedented drought and bushfires that scientists have linked to climate change.
