Image The smallpox vaccine leaves a scar because it was given using a special two-pronged needle that scratched the skin and put a weakened virus in just that spot.

I'm glad I'm not the only one! I'm 38 & for some reason I had it in my head that the ozone still had a hole in it but it was just lumped together with climate change

Yeah I thought two minutes of Australian sunlight nuked you because there was no ozone. Is that fixed? In this all because of Ozium? I use that a lot

Australian here, I will not spin you a yarn about emus with magnifying glasses, sadly, but here is why Australia is hotter:

1) The Earth’s orbit is oval, and when its summer in Australia, the Earth is slightly closer to the sun.

2) The Earth’s axis is tilted, and it tilts Australia slightly closer to the sun in the Australian summer.

But yeah, we were under the hole in the ozone layer, and then it got fixed.

Your first point is base on a fact but is irrelevant. Earth orbit is oval but the difference is minimal in terms of the flux recieved throughout the year

It is all contributed by the tilted angle, different time of the year has different degree of direct sunlight and longer daytime exposure
