    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.
