Forget Brisbane, Sydney, New York, Paris. What is the
global trend??? Do tell me because I don't really know. All I know is Melbourne summers have had more of a tropical feel in recent years...
With a chaotic system like the weather you can always find
many local exceptions to a
global trend. That's the nature of the beast. And this can be easily exploited to build a convincing, yet ultimately false, argument against the global trend whatever that might be.
