The unprecedented rains and record flooding on Australia’s eastern coastline might last for quite some time next year, but new research suggests that climate change has pumped more moisture into our atmosphere.

Our research published today in Nature Climate Change examines the far-reaching effects on the global climate if this atlantic conveyor belt collapsed completely.

The Atlantic Circuit consists of a massive flow of warm tropical water to the North Atlantic, which helps to keep the European climate mild, while giving the tropics a Chance of Losing Surplus Warmth.

That would mean more rainfall falling on eastern Australia and worse droughts and bushfires in the southwestern United States.

Both contributed to some of the wetter weather ever, with record flooding in New South Wales and Queensland.

This excess of Tropical Atlantic heat pushes more warm humid air into the upper troposphere (some 10 km into the air), causing dry air to fall across the Eastern Pacific.
