Australia Rainfall and droughts Have No Obvious Trend Related to CO2 Levels

Australia overall:
Droughts In 
the 178 
year record, 
reveal no trend

178 years 
of CO2 
emissions 
have no 
measurable 
effect on 
rainfall in 
Australia.


The rainfall trend 
depends mainly 
on the start 
and end date 
you choose
for the trend.


Minor Trends:
Drier than usual:
  in 1880s. 
  in early 1900s
 just after the 1980s


Minor trends:
Wetter than usual:
  during World War I 
  just after WWII 


-- Much of Victoria has
lower rainfall per decade. 

-- NSW, where most of the fires 
have burned so far in 2019
and 2020, has the opposite trend.  

Which one is climate change?
