And Donander, you know perfectly well that it is not the temperature on any particular day that tells us anything. It is the number of hot days in a row and in a full year that points to change, or not. i.e. How long are the heat waves, and are they becoming more frequent as well as more intense.
No Warrigal. I don't know that. Neither do you.
I have downloaded the
BOM's figures for Melbourne (
1855-present).
The data (.CSV file) starts recording in 1855 but the text file (IDCJAC0010_086071_1800_Note.txt) included in the download says:

I've read that Australian climate records are in a bad way ..... nothing there to alter my opinion. Anyway, what I wanted to post is the graph I created from the Melbourne data (max temps):
... from this location:
Melbourne BOM Regional Office, slap bang in the CBD of a city of more than four million people!
Maybe a degree almost 160 years with the
UHI factor? UHI affects all cities to some degree.
Speaking of UHI, some years ago, I saved this URL (
UHI) from Melbourne University. It no longer works, probably because it didn't fit the warming narrative ...... sigh.
To complete the picture (somewhat), I have re-graphed the Cape Otway Lighthouse data with the latest data available from the BOM:
As soon as you depart the cities, the picture changes ... we're being sold a pup.
