Where I was born and raised and spent the first 43 years of my life was a "lovely and cool" place as well.
It used to rain regularly, snow sometimes and summers were a balmy 33 to 35 at most. There would always be an afternoon storm that would cool it down nicely. There was fresh green grass everywhere, fat cattle and sheep, running rivers and creeks and waterfalls.
When I was invited to "come live in Adelaide" I had no idea (and was too busy to check) things like rainfall, temperature etc.
My first day here was 45 deg and was a hell of a shock after stepping off the plane coming from floods and days of rain. Even though it was January the temperature at "home" was only about 20 deg. That heat flattened me for 3 days!
Everything suffers under the heat, everywhere is brown and dead and the only green is on lawns of people rich enough to pay the very expensive water rates.
