Shock-me-not: CO2 doesn’t cause multiple back-to-back disasters in Australia

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.

Kenneth Richard, NoTricksZone

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.

Climate disasters are less costly, less deadly, and corporate warnings are just $1T of hot air

Hitting the presses today, the vacuous news that lots of companies picked huge numbers out of the air using broken models to guess hyperbolic climate losses coming in the next five years, counter to all the trends for the last hundred years which show declining losses on a GDP basis. The world got warmer but the disasters got less nasty. Less bushfire, less cyclones, less tornadoes, less death per capita. The trends are all good. The only thing that’s up is the number of panic merchants.

World’s biggest firms foresee $1 trillion climate cost hit

LONDON (Reuters) – More than 200 of the world’s largest listed companies forecast that climate change could cost them a combined total of almost $1 trillion, with much of the pain due in the next five years, according to a report published on Tuesday.

So hundreds of companies have offered the climate world a free hit for PR by making a guess. They fall into two kinds of companies –The badgered and harried and the profiteers. See below for examples. Firstly, here’s the only chart that matters.

Global Weather losses are down:

If CO2 causes climate events we need more of it. The […]
