The extreme weather appeared to be the result of a relatively normal weather system bringing rain that had been turbocharged by ocean and atmospheric warming, said Janette Lindesay, a climate scientist at the Australian National University. “It’s highly likely that global heating has played a role in the intensity of the event,” she said.
Honestly it’s hard to say for sure exactly what will happen with climate change. Some areas that aren’t deserts now will become deserts, some desert areas will become hotter and even more inhospitable than they already are, but some areas will get increased rainfall and we may see the transition of some currently temperate and desert areas to something more closely resembling a rainforest.
These unprecedented and usually violent storms could become more common in the area and they may need to look at ways to remove water from the area as fast as possible instead of trying to find ways to keep it.
