Extreme climate and weather events

This high impact flooding was a compound event, an event caused by multiple hazards or drivers.

The average temperature over Australia has warmed by 1.47± 0.24°C since 1910.

As the climate continues to warm, more and more ice shelf collapses are forecast to occur, potentially leading to an acceleration of sea level rise.

Heatwave conditions are expected to continue to worsen as the climate warms. The ARC Centre of Excellence for Climate Extremes is continuing to research links between heatwaves and weather systems, soil moisture and climate change.

We will need a longer time record to be able to identify a climate change signal in Antarctic extreme events.

Rapid declines in sea ice from spring 2021 continued, leading to record low extent in late summer 2021-22.

By the end of the first week of March, both Queensland and New South Wales had received more than a year’s worth of rain in a month.

The ARC Centre of Excellence for Climate Extremes is continuing to research and understand the drivers of these sea ice extreme events and sea ice predictability.

It is unequivocal that the increased CO2 in the atmosphere is warming our climate.
