Of course, I’d be worried about sudden or adverse changes in the climate, too… if there were anything to worry about.
But I can’t for the life of me (or you) see anything worrying in the climate. The local weather is a bit annoying but that’s just B.A.U. in Melbourne. We live between a big, hot, dry continent and the world’s coldest and windiest sea… the weather is bound to be ‘interesting’. [Click to see a larger size]
Weather is not climate… still, 166 years of temperature records does tell you something about climate. Not much, of course: the climate we have today has been wandering around the gauges for 2.6 million years, since the last Ice Age! A mere century-and-a-half isn’t much of a sample. But it tells us something about recent climate.
What does it say? It says “relax!” There has been a tiny, teensy, barely-even-noticable creep-up in maximum temperatures over more than a century and a half (using carefully recorded Bureau of Meteorology data) — see the red line in the graph — but it’s hardly visible, let alone worrying!
We are looking here at a tiny-teensy change ove a century-and-a-half big of much bigger variations (30° plus) in average temperatures that are unconcening.
And, notice, that the hardly-visible-trend seems to be due to a slow, slight uptick (no more!) in the lowest-maxima, not to any increase in maximum temperatures! Why do the lowest maximum daily temperatures seem to rise a tiny bit? Perhaps because Melbourne is a big city that — like all cities — has grown a little warmer overnight than it once was.
But what do you think the insane, COVID-zero, Victorian government wants to do about this non-event… ?
