I didn’t want to write about the recent weather in Australia. I had felt that it had been covered pretty well already (for example, here, here and here). But it’s 45.8 degrees Celsius in Sydney today. For all you Americans, that’s 114.5 degrees Fahrenheit. So, short version – it’s really, really, really hot out there. Record-breakingly hot, just a week after we last beat 40 degree mark.
Really hot weather is actually pretty rare in Sydney. Usually we scrape the 40 degree mark once every 2-3 years and then drop down to temperatures in the high 20s/low 30s. That’s why the second 40-plus degree day in a fortnight is somewhat alarming, especially combined with the heatwave that moved across the United States during the northern summer. The US National Climate Assessment report, which came out last Friday, also contains little in the way of good news.
Everywhere, the evidence for anthropogenic climate change seems to be piling up, both scientifically and anecdotally. It will be interesting to see whether or not this brings about any real change.
