I do understand the difference between climate and weather yes.
It's a reality though that "extreme" weather events, if they start happening rather often, do point to a change in the climate since "extreme" is by definition with reference to the established climate. In that sense I'll draw your attention to the weather forecast for Monday 30 December 2019:
"Very Hot. Late Storms. Maximum 40"
Now that's for Adelaide? Nope.
Perth? No try again.
Melbourne? Nope.
Sydney perhaps?
Nah - the answer is Hobart.
Now as someone who was born in Hobart and has lived most of my life in Tas (now in SA) I'm rather familiar with the fact that Hobart's all time record temperature was set at 40.8 back in the mid-1970's and we had to wait until 2013 to exceed 40 again. Since then another part of the state reached 42.2, an all time record (Hobart's 40.8 was the previous state record), and if it gets to 40 on Monday then that'll be the third time this decade.
One data point proves nothing, I agree with that, but when it happens 3 times in a decade versus only two previous known occasions since European settlement well then that does raise some questions. Especially given that the same trend is cropping up right around the world.
That doesn't prove CO2 as the direct cause but the evidence that warming is taking place seems pretty clear to me. There's simply too many data points coming up which point in that direction to ignore - Adelaide's all time record was set this year among many other places.
Needless to say, there's rather a lot of things in Tas that just aren't set up to cope with the heat. Plenty of homes and workplaces which can be relied upon to be a few degrees warmer inside than out with no air-conditioning and a population that isn't used to extreme heat = pretty unbearable in practice.
