Broecker: Fixing Climate

Fixing Climate is both interesting and useful but not in the ways that the authors intended. That’s not entirely their fault, since climate science and mitigation have changed enormously in the ten years since it was published.

The book tracks the life and work of Wallace Broecker, who was born in 1931 and was just the right age to become a pioneer and then a leader in the (then) very young field of climate history and (hence) climate change. Continue reading “Broecker: Fixing Climate”

Townsville’s 2019 floods

The Townsville flood of January-February 2019 was, like cyclones Althea and Yasi, one of the extreme weather events which define people’s lives in the city. Two months later, “How did you go in the floods?” is still the first question we ask friends we haven’t seen for a while. There’s a lot for Green Path to say about it but whatever we publish now will be incomplete so we will update and extend it as appropriate, in separate posts if justified by the amount of extra material.

Let’s begin with an overview of the weather event and its immediate consequences.

The weather event

A low in the monsoon trough over the Gulf became a rain depression and drifted South and East until it settled over Townsville, where it stayed much longer than “normal” (we will have to return to that concept later) and dumped an inordinate amount of rain on us over about ten days – say 29-30 Jan to 7-8 Feb.  Continue reading “Townsville’s 2019 floods”

The Dry Season continues

White-gaped Honeyeater
Oooh, that was good!

We’re well into the Dry season now and the birds come to water whenever they can. These White-gaped Honeyeaters (Lichenostomus unicolor) came to bathe under the sprinkler this morning.

Rain? What’s that? We had a few drops (almost few enough to count individually) a couple of days ago, but before then?

I had to look at the BoM’s records. They show we have had nothing over 0.2mm on any one day all the way back to early July when we had 12.4mm one day and a sprinkling on the days either side of it. June’s total was … wait for it … 2.2mm and in May the total was only 1.8mm. We had 10 mm in April but, really, it stopped raining at the end of March.

We have had less than 30 mm in a bit over five months. Continue reading “The Dry Season continues”

Townsville’s 2018 Wet Season and what comes after

We’re officially in Winter now and I reckon we moved definitively into the Dry season a fortnight ago, so it’s worth looking back at the Wet and seeing what’s likely to happen to our water supply in the Dry.

Wet season rainfall and the year to come

Here comes the rain! Hervey’s Range rain radar, 9.15 pm on Feb 20, 2018

BoM climate data reveals that our rainfall so far this year, Jan – Feb – Mar – April – May, was 118 – 285 – 343 – 10 – 2 mm, for a total of 760 mm.

Of that, 435 mm fell in the last week of February and the first two days of March when a rain depression was trapped over the city; an unusual but very welcome event which made the difference between another really  weak Wet and a nearly-average one.
