This was an ad for AGL gas in 1983, broadcast on Australian TV, showing their future vision of Sydney’s weather.
In it, you can see beautiful shots of Martin Place covered by snow, and people ice-skating in Circular Quay, with the Harbour Bridge visible in the background.
You see, climate change afficionados had slightly different expectations back then.
I am in full agreement with the first comment on the video:
“Is the pattern of the world’s weather changing?” Ha Ha. Al Gore must have been in town. This ad of course dates from the days when the coming ice age was the big climate scare. Back when silly religions used to sacrifice a goat in a futile effort to influence the weather, rather than trying to sacrifice entire economies.
