Multiple Cyclones, Fires, Floods and Heatwaves striking Australians at same rate for last 55 years
Gissing et al looked at insurance losses and plotted all the times multiple disasters piled up on each other in a three month period in Australian history. Despite the monster headlines and three quarters of all human CO2 emissions occurring since 1966 there was no trend.
Three new studies affirm there has been no significant change in natural disasters, precipitation, or bushfire across Australia for the last several decades.

From the paper:
“Here we utilise an Australian natural disaster database of normalised insurance losses to show compound disasters are responsible for the highest seasonal financial losses. … There has been no temporal trend in their frequency since 1966. “
The predominant and most predictable driver of climate-related disaster events is not anthropogenic global warming, or CO2 emissions, but the El Niño Southern Oscillation.
Bad things happen:
Global levels of CO2 rose from 320 to 405ppm and made no difference to Compound disasters.
