A pattern of extreme weather should not be confused with climate change.
The recent heat wave across much of Central Australia and its occasional extension east and south is a pattern of extreme weather. Climate is the recurring patterns of weather that inure us to such extremes. The climate of Alice Springs is exemplified by 1887, the previously hottest January with an average maximum of 40.7oC. The extreme, nearly 5oC above the long term January average, was made possible by a spell of 11 days over 40oC, a brief respite then another 10 days over 40oC.
Climate change, of course, is a persisting significant departure from the experienced pattern of weather. The current pattern of extreme weather is not outside the envelope of experience that describes Central Australian climate.
