Yes, it may. But it's doubtful it will be on a large scale, or even a particularly visible scale. So a bit of extra cosmic radiation causes additional genetic mutations perhaps, but really, people aren't going to start dropping dead of sun exposure. Well, except the folks with Melanoma, but that's not exactly new.

As for YECs... what? No. Young Earth Creationists are a crazy bunch who try to prove Religion with Science. That in itself isn't wrong, it's their particular methodologies and unsubstantiated theories, which they defend with fervor in spite of their illogical and obviously false nature. Filling in the blanks with "God Dunnit" has no place in science. I don't get their obsessive need to explain clearly unscientific ideas with science. Science and religion are not mutually exclusive, but they can not be used together without compromising one or the other.
