The Melbourne ‘climate emergency’

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… ?
