I was reading a paper in Geophysical Research Letters on a study conducted on Australian hot records (high maximum and high minimum temperatures). If the climate is stable, the number of record highs should equal the number of record lows. However, during the period of 2000 - 2014 the number of record highs outnumbered the record lows by twelve to one on average.
One of the things I keep saying about regional temperatures is that we are discussing global warming, not xxx regional warming. That applies here, as well. The term is 'global' warming, not 'Australian' warming. However, when you combine many regional trends you get a global trend. And, in fact, the Australian trend is characteristic of the global trend (see the Climate Change Institute's Climate Reanalyzer for a global view).
It has been said that when we see the effects of climate change it will be too late. Hopefully, this is not true because we can certainly see the effects in Australia, as well as other parts of the world.
