Whole of NSW coast shrouded in dust and smoke, 47C in Hunter Valley (75 years ago)

This week 75 years ago. Dust storms, bush fires and unbelievable heat across New South Wales. 118 fahrenheit is 47 degrees C, and there were 100+ temperatures in many places. The sun appearred as a “red sky”. A dust storm created a “terror” in Mildura (just like last week in 2019).

In Parkes, it was the worst dry spell on record. People were going without milk because the cows have died. Thanks to Siliggy, Lance Pidgeon. Holy apocalypse!

RAGING DUST FURY INLAND, STRANGE CITY LIGHT GLOW The Sun, November 1944

The air was calm in Sydney today, but diffusion of sunlight through a dense blanket of fine dust bathed the city in a strange orange glow. Practically the whole of the NSW coast this morning lay under a shroud of yellowish-red dust and bushfire smoke blown from inland regions.

Maximum temperature in Sydney today was 98.7 degrees at 2.55 pm. Early reports at the Weather Bureau today indicated that a heatwave, unprecedented in intensity, was raging’ practically everywhere in northern, western and southern NSW.

Temperatures in many centres remained at over 100 degrees throughout the week-end. At Jerry’s Plains, Hunter Valley district, the mercury [...]

The Sahara may flip from desert to grass every 20,000 years. Blame The Sun.

MIT researchers think they have solved a bit of a mystery regarding Sahara dust, but if they’re right it means the Sahara Desert has already come and gone 3 – 5 times since humans walked the Earth. The Sahara is the largest desert on Earth, and this would be the largest and longest drought “ever” on the planet (as far as we know).

UPDATED: Commenter Javier points out these drying cycles were known years ago. (See below)

This would rather redefine the whole idea of “climate change” — 3.5 million square miles of Green Sahara turns into Dust-bowl Sahara — and it’s all thanks to sunlight. The drought doesn’t just last 7 years, but more like 7,000. And it’s happening over 9 million square kilometers, an area larger than Australia. The major climate models leaned towards the monsoonal cycle, rather than the longer ice age one. So this theory may have resolved one of the 495 contradictions in climate models. Or not. But the bigger message here is that the sun causes climate change and on a massive scale.

The Sahara is the largest dust bowl in the world, dumping 10 million trucks of dust across [...]
