CSIRO research commissioned by the federal government suggests climate change could dramatically reduce the number of tropical cyclones in the Australian region and decrease wave heights on the nation’s east coast.

The surprise findings, which appear to contradict some common predictions about the impact of climate change, are contained in scientific papers on “Projecting Future Climate and its Extremes”, obtained under Freedom of Information laws by The Australian Online.

One paper, by CSIRO research Debbie Abbs, found rising temperatures could halve the frequency of tropical cyclones.

“Climate change projections using this modelling system show a strong tendency for a decrease in TC numbers in the Australian region, especially in the region of current preferred occurrence,” Dr Abbs said.

“On average for the period 2051-2090 relative to 1971-2000, the simulations show an approximately 50 per cent decrease in occurrence for the Australian region, a small decrease (0.3 days) in the duration of a given TC and a southward movement of 100km in the genesis and decay regions.”
