Before climate change: Falling rocks set fire to 10% of land, trigger mini ice age for 1000 years

Another day, another apocalypse. Life in a perfect climate

Poor sods. After 90,000 dismal cold years things were finally just warming up when a  bunch of comet fragments from a a 62 mile-wide comet, crashed into our atmosphere. It was  around 13,000 years ago, and the fireballs started the ultimate black Saturday blaze which converted 10 million square kilometers of wilderness into unauthorized carbon emissions*. Somehow, all those reckless greenhouse gas additions didn’t seem to stop the airborne dust triggering a return to a mini ice age for a thousand years. It also punched a hole in the ozone layer meaning everyone probably had to wear more yak-fat sunscreen or get more skin cancer (I suspect data is bit lean on that).

Glaciers started growing again, some ocean currents changed and thus the Younger Dryas unfolded according to a couple of new papers.

In a fairly dramatic shift of landscaping styles, mother nature razed whole pine forests and replaced them with poplars.

Gaia is full of surprises: in the end, falling lumps of ice set fire to 10% of land on Earth, and making 10,800BC the worst carbon footprint since the last 62 mile wide rock hit Earth. Primitive tribes […]
