![]() ![]() Scientists have known for a long time that a warmer atmosphere is able to hold more water.Īn oft-quoted figure is the “Clausius-Clapeyron equation”: for every 1C of warming, the atmosphere can hold about 7% more moisture. It is these types of downpours that climate scientists say are becoming increasingly intense in Australia because of a warming planet, and will probably intensify further as the planet warms.Īustralia’s landmass has warmed by almost 1.5C since records began in 1910 – a level of warming slightly higher than the global average. Much of the flooding in recent weeks has come from downpours over the course of a few hours, giving authorities and the public little time to prepare, and pushing storm drains beyond their design limits.
