Due to family reasons, I can’t give much attention to this blog for a while.
I’ll leave you with two graphs to contrast climate alarmism about heatwaves with reality.
Dr Sarah Perkins of the Climate Change Research Centre and Dr Karl Braganza were in the news this week claiming that
“we’re definitely seeing more heatwaves across Australia”
“the number of days that belong in a heatwave each season — has been increasing since the 1950s.”
“Brisbane has been getting heatwaves in spring”
Let’s look at Brisbane. Dr Perkins, a heatwave expert, defines a heatwave as “three days in a row of temperatures in the top 10 per cent”. The top 10% of days are those with a temperature above 29.5 degrees Celsius. Yep, 29.5 C is apparently an extremely hot day at Brisbane Airport! This shows consecutive days above 29.5 C- the red line is the 3 day heatwave benchmark. Note the linear trend.
This shows the highest temperatures reached in 3 day heatwaves:
Just two graphs refute all of the above claims about Brisbane:
definitely NOT more heatwaves
definitely NOT more hot days each season since the 1950s
and Brisbane has ALWAYS had heatwaves in spring, but not so many nowadays.
There has been a slight increase in the number of standalone days above 29.5 C (0.17 days in 66 years), but ‘heatwaves’ have been getting COOLER.
