"Human carbon burning may lead to a similar scale of planetary catastrophe."

The Day the Skies Went Dark

Michael Benton of the University of Bristol and Monica Grady of the Open University detailed the catastrophic effects of the meteorite impact that occurred 66 million years ago, outlining both the immediate devastation and the long-term planetary collapse.

The First Minutes: Hell on Earth

Within minutes of the impact, any creature within a 2,000-kilometer radius faced a nightmare scenario. A bright fireball and a deafening sonic boom announced the event near the impact site. This was followed by a cascade of horrors: incineration, mega-tsunamis, violent earthquakes, hurricanes, and widespread fires that erased life across a massive region.

The Long Winter: A Decade of Darkness

While the initial strike was apocalyptic, the long-term effects proved even more devastating.

Within just one hour, a thick shroud of dust encircled the entire planet, blotting out the sun. This triggered a catastrophic drop in global temperatures. According to the authors, the world cooled by 5°C within a single week, plunging the Earth into a winter that would last for over a decade.

The result was a mass extinction event of staggering proportions. Approximately 75% of all species on Earth vanished.

A Stark Parallel to Today

The researchers concluded their analysis with a grim observation. They noted that current human carbon burning may be leading the planet toward a catastrophe of a similar scale, drawing a direct line between the ancient impact and modern climate change.
