As my first interactive post, I created a plot using data from the Bureau of Meteorology.
First, this takes the average temperature per month in Melbourne and averages it across 4 different decades.
Here is the max monthly temperatures, from 1940-2015. The general trend does not show a strong pattern - some years are warmer, some are cooler.
And here are the minimal monthly temperatures. This is more insightful - it seems to be getting warmer across the decades.
Is there evidence for climate change? I’ll let you make your own call.
