If your intention is to deviate it, there are much better solutions but that takes a lot of time and planning.
In fact the real information here (which is usually lacking in amateur discussions) is how much time do we have.
For the record a dinosaur like event wouldn't wipe out humanity at all, just kill a lot of people especially in the aftermath because of possible food shortage and famine.
Not everyone would die though, humanity as a species would easily survive.
