New research on asteroid dust and immediate heat trapping

Paleontology

Recent research suggests that debris from the asteroid impact heated the atmosphere within minutes. Fine dust trapped this heat, potentially killing the dinosaurs within hours. We have spent years focusing on the slow freeze of a nuclear winter. Shifting the perspective to a rapid heat trap changes the timeline of the extinction significantly. It is a heavy realization, but there is something rewarding about finding these specific details that help us piece together the actual sequence of events.

Suppose the atmospheric heat was rapid, but would the thermal inertia of the oceans have provided a buffer for marine species? The timeline for aquatic extinction might still follow the slower model.

But wait... if the heat trapping happened in hours... how did the dust stay suspended in the atmosphere long enough to create that effect before the initial shockwaves cleared it out?

We see this with massive wildfire plumes now. The local heat trapping is intense and immediate, which makes the global timeline feel more plausible when you look at how air pockets actually behave.

The thermal radiation from re-entering ejecta is well documented. The infrared pulse alone would have turned the atmosphere into an oven long before the soot settled.
