110 years of Australian temperatures

I’m a sucker for a good graphic and here’s one of the best.

What I’ve posted here is a screenshot of the BoM’s page, but clicking on it will take you straight to the original page where each of the individual maps is slightly larger and is linked to a full-page version. There’s also a link to a poster-size pdf if you have a place for it; a classroom wall would be an excellent spot.

Green Path has more climate change resources in a dedicated page, and the BoM has lots more on climate change, too – start here if you like solid data displayed in clever graphics.

The Brick – a fable for our times

I wrote this parable in 2009 as a contribution to an online debate and then forgot about it for years. I recently came across it again, however, and thought it still deserved readers, so here it is. Feel free to share it.

The Brick

“G’day Tom,” said Jamie, “How’s things?”

“Not too bad, mate.”

“You’re limping, though. What happened?”

“Oh, I dropped a brick on my big toe when I was clearing up a couple of days ago. Continue reading “The Brick – a fable for our times”

Many Peaks Range and Magnetic Island

My very first impression of Townsville’s landscape, thirty years ago, was of dead-flat land interrupted by peculiarly isolated hills and ranges, and it has only been reinforced over the years by views and events.

The views? Getting to know the topography from the top of Castle Hill, Mt Stuart or (most recently) Mt Marlow on the Town Common reveals a coastal landscape of mangrove flats rising (minimally) to the suburbs which wrap around the bases of the hills, with Ross River, Ross Creek and the Bohle River winding lazily through them.

Ethical investing – using our money for good

Ethical investing is currently in our news because of a court case brought against a large superannuation fund, REST Super, by one of its members for failing to adequately consider financial risks arising from climate change.

Also, as it happens, a member of one of the more civilised online forums asked very recently about ethical investing and received some good answers. That synchronicity encouraged me to turn the forum posts into something more readable for Green Path by combining and rewriting the replies of several members; that means it is not all my own work although it appears under my name as usual.

We will begin with the online Q & A, and then return to the court case. Continue reading “Ethical investing – using our money for good”

Townsville’s weather in 2019 – what happened?

The last few days have brought us some genuine early-Wet weather: heat, humidity and thunderstorms. We have recorded our first double-digit rainfall totals in months, so it feels like a good time to see what really happened last year.

The BoM released its Annual Climate Statement for 2019 a fortnight ago. It named last year as Australia’s warmest and driest on record but there were notable local exceptions: Townsville (1761 mm) and the middle of Western Queensland scored their wettest year on record. (So did the tip of Cape York, one spot on the WA coast and one spot on the Tasmanian coast, which reinforces the feeling that our weather is getting ever crazier but is not otherwise relevant here.)
