For example, Australia used to be mostly covered in water and attached to Asia, but the water retreated and we had millions of years of forest gradually drying out until now it's desert. Imagine how much the local weather varied over that very long time.
One theory I read was that we have actually been in an Ice Age for more than a million years and are now warming out if it. Before that, it was warmer when the dinosaurs were about.
Climate is a fascinating topic, but I have trouble going beyond short term thinking about weather to appreciate the long term climate trends.

I often wonder if the dinosaurs had similar conversations just before the big extinction. " Don't worry, Shirl, it's just a trend. "

You are right Mick, I refuse to answer.

Bob, I have to ask, Australian meteorological records? A grain of sand in the Earths deserts of time.

I have a fairly accurate weather station and can differ with the official temps/humidity/rainfall accorded to our
"Area" considerably e.g. +/- 5°C.

We are near Dayboro and our BOM observations are based on Redcliffe. A fair geographical difference there. I know it can be blowing 15-20 knots where you are and we don't have zephyr.

We can all throw our 2 bobs worth in ad nauseam, the truth is, the climate is heating up. The sooner we stop playing games and recognise that fact, the better off we will all be. United we conquer, divided we go the way of the dinosaurs.

I have to ask......what is a Plane tree?

to Mick Marsh, the reason i questioned your trees was that most Australlian natives don't suddenly drop their leaves in autumn. It appears to be all the imported ones that do that. My yard is full of local native trees and shrubs , some less attractive than the English and European ones. I happen to like frangiapanies but right now mine are making a terrible mess. The natives aren't.

.....treid every possible way to spell frangipanie but still says I'm wrong...

What about St Kilda Road?
When I worked for BMW our headquarters were in St Kilda Rd. It was achingly beautiful in Autumn.

I believe there is only one Australian tree that could be termed deciduous,....nothafagus variant, commonly called myrtle or beech. Plane is a specimen tree ,large leafed ,lovely grey ,green trunk, but an absolute mess at leaf fall ,from the " old country ", like oak and chestnut and poplar.

bombax Ceiba
Native Vineforest Deciduous

Amazingly resilient in cyclones, I lost a truckload of red cedar, brushbox and northern silkies in
Ita but the massive bombax trees just dropped a few branches

Looks can be deceiving - frail appearing woody softwood tree
Completely deciduous to the point of looking dead in the rainforest

Anyways I’m sure there are many native decidious trees

From what I have read , plane trees are used by councils for several reasons , fairly drought tolerant and provide shade in summer and open up in the cooler months by dropping their leaves.
Unlike eucalyptus leaves they readily break down , esp if run over by a lawn mower first , then applied as mulch. A regular job every utumn when I was a kid then later with the local council.
