I was in Barossa last week and noticed lots of cottonwoods, with no native birds in them, merrily shredding their leaves.....what a mess.

Some of mine are.
The apple, pear, peach, avocado and olives aren't.
Nor the mandarin.
I don't think the christmas plum is either.

Why do you ask?

Talk about mess. The Victorian councils seem to have a love affair with plane trees, horrible things.

Mick, please, instead of firing from the lip, read the article.

No it didn't. Thirty five it got to last week.

I read it ages ago.

"First time in history". Well, that's false misleading hyperbole right there.

Sorry mick, your credibility flew out the window. Keep trolling, you'll get some one.

Why is it, Bob, whenever someone has a differing opinion to you, you immediately launch into a personnal attack?
Rhetorical question, Bob. Don't bother answering.

Adelaide got to 36.3°C on Monday 9th and Wednsday 11th this year, 2018.
Adelaide (West Terrace / Ngayirdapira), SA - April 2018 - Daily Weather Observations

Cooler than the 36.7°C on April 3, 1986.

Cooler than the 36.9°C on April, 2, 2005.

Cooler than the 36.9°C on April, 9, 2005.

It's not uncommon to have temperatures in the thirties in April in Adelaide. Adelaide is a hot, dry place, well, compared to Melbourne.

The Bureau of Meteorology records began in 1887 But the article states:

History is a very long time. Way back when the pyramids were being built and Moses led the slaves across the Sinai Desert, the world was a much hotter place.

And it was way hotter during the Cretaceous

Makes a 2°C increase in average temperature seem rather cool.

First time in history. here is the comment in the right context.

You are right Mick, I refuse to answer.

Yes, but that's recorded history, which isn't that long. A couple of thousand years of short term weather doesn't tell us much about long term climate changes over many millions of years.
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.
