In a mysterious reversal, Earth’s atmosphere has gotten less dusty
On this day in 2009, Sydney woke to a red dawn.
A strong low pressure system whipped up 15 million tonnes of dust from the deserts of central Australia & carried it across eastern Australia, as far north as Cairns. Some even settled on the mountains of New Zealand, tingeing the snow red.
