The Bureau of Meteorology and CSIRO's biennial report findings - increased temperatures, reduced rainfall and increased extreme fire weather days - will not come as a surprise.
We know the climate is changing, leading to more frequent and extreme weather, as well as sea level rise. What is unclear, however, is when specifically we will see major changes in risk and consequences.
This makes planning and adaptation more challenging, but it should not be a reason for inaction.
Take the ice on Greenland, for example. CSIRO's Steve Rintoul said if that melted, there would be enough ice to raise global sea level by seven metres. What makes this even more challenging is that scientists are not sure at what level of temperature rise this melt would happen.
