Why did Earths atmosphere fail to lessen the effect of the asteroid that wiped out the dinosaurs?

Why do you think it didn't lessen the effect? Did you compare it with the impact of a similar object upon a body with no atmosphere?

If a small part of the asteroid burned up at high altitude, the atmosphere did "lessen" the effect but nowhere near enough to prevent extinction. I suppose if earth had no atmosphere, there wouldn't have been so many fires and so much soot to block sunlight but in that case, there wouldn't have been a biosphere to degrade in the first place. :)

The asteroid was such a big and dangerous that it burned up all atmospheric and biospheric layers producing harmful gases with great force.
