In the last century, Australia's average temperature rose by slightly less than one degree over the pre-industrial average. Without concerted action by all countries, including Australia, the world is on a path to exceeding 4°C by the 2060s. While some further warming is already locked in to the climate system, the worst is still avoidable.
The tasks now are to avoid the unmanageable consequences of full-blown climate change and, at the same time, manage the unavoidable. This means recognising the full human cost of disasters, an early investment in community resilience—strengthening communities’ capacity to recovery, as well proper resourcing of emergency services.
To delay action is to court a lot of unnecessary human suffering.
