Odd thought: if an asteroid landed on the East Antarctic ice-shelf (some 3km thick), we'd see water vapour rise up. But would we see as much ejecta of rock? If not, would the heat wave caused by re-entry be substantially less severe?
Which formulas did you used for this calculations? How calculate temperature of the heat produced by ejecta firestorm at given distance from the impact? Website "Earth Impact Effects Program" by Imperial College, London don't calculate ejecta firestorm consequenses. And by the way, this website also don't calculate ejecta thickness at distances > 10000 km from the impact.
I got these from this paper "An experimental assessment of the ignition of forest fuels by the thermal pulse generated by the Cretaceous-Palaeogene impact at Chicxulub" The website indeed caps the ejecta thickness at distances > 10000 km but it's a convention, their equations are applicable for further distances
It turns out that at over 10000km, the ejecta arrival time is much longer than one hour, approaching 7 hours at around 18000km. At those timescales, Earth's rotation would affect the arrival of the ejecta. It was capped for simplicity.

Meanwhile in Honolulu: A little warm breeze
1:04:55 100 celsius heat wave cooks me alive
0:05 you know it’s hot when the temperature is wtf° 💀
Pretty sure this asteroid is slightly bigger than the dinosaur-eliminating Asteroid.
Yeah. It’s 3 and a half times more strong than the chixilub asteroid
59:22 I'm cooked by a giant 250°c heat wave

Such an impact excavates the crust down the depth of tens of kilometers. Ice sheets and oceans don't really affect much of anything.
Hawaii: It's just the average high temperature, why are they so dramatic?
How can heat wave move faster than speed of sound and airblast? How it would felt on the distance, like hot wind or what?
the heat wave comes from ejecta atmospheric reentry, which move at orbital velocity

@@Kaldisti Thanks!

A noticeable chunk of the Earth with surface temperature >1000000 degrees Celsius 😬
What's the last city to get a temperature over 69 degrees C?
Likely San Francisco
51:08 So I was cooked by the heat wave
46:29 i am cooked by a 300 degree heat wave
whats the name of the programe? i would create things like this too, just on other places
pretoria: WTF°C
Im wondering where's the first place you'd have a decent chance of surviving the temperature
Hawaii x)
1:23:21 i think this is about when i start to feel the effects
0:00 21°C
0:05 WTF is kilometer°C
What does WTF Celsius mean?
I hope this is a joke
@@jusden2.083Actually, you hope it isn't.
Means “wasn’t this fun” as you are vaporized
Fireball temperature, tens of thousands °C
means >50000 celsius
1:07:12 I am getting the heat wave abt now
Hit by the heat around here 1:24:04
I am literally at the center of the heat wave at that time, only 100°C. Thank God that I live in the Midwest!
WTF°C 🤣🤣🤣
46:07 im fried
