The good news is we’d be pretty dead if we had no atmosphere anyway, plus there’d be no clouds.

good news
Ummm
great news
Ftft
Oh.
How?! How is there an xkcd for EVERY gawdamned thing?!
XKCD is an allknowing timetravelling entity.
Can confirm. XKCD spoke at my college and signed my laptop.
Ooh, now I'm wondering if Doctor Who will make a reference... 😱
Confirmation bias?
Has xkcd done an xkcd on xkcds?
Seemingly not officially but there's 
the unexplained meteorological phenomenon is simply dubbed a “Skrillex Storm”—because, in the words of one researcher, “It had one hell of a drop.”
This is amazing.
If there was no air I'm pretty sure clouds wouldn't form in the first place.
Also, we'd all be dead.
Oh, you and your facts.
A cubic foot of water weighs just under 62 and a half pounds. Atmosphere to slow it down or not, having that land on you from altitude would hurt.
They mentioned a 2 in. thick sheet of rain falling, which is ~288 cubic in. per 1 foot x 1 foot area, about 10 lbs of water. Falling as a flat sheet at terminal velocity would hit you with a force of 127 newtons. What that means as far as injuries go I have no idea. I'm sure it'd cause a nasty headache at the least though.
Fair warning, I'm terrible at math so I could be completely wrong
Terminal velocity is only as fast as it is because of air resistance. With no air resistance, the only limiting factor of speed is starting height.
It’s like the experiment with the feather and the hammer they did on the Moon.
I did tweak the drag coefficient while doing the math but I had no idea how to figure out what would be most accurate. The number I got there is with a drag coefficient of 1
Energy would be better to look at than force, since at any distance the force is the same (mass and acceleration aka grsvoty are both static)
Fun fact
Definitely not
Reminds me of that page in the Bone comic where the snow comes down all at once. I loved that scene!
