Forum:Question about Solemn Warning

If my opponent activated a monster effect that says you can discard that monster to special summon another one, could I chain Solemn Warning even though there is no card that will be destroyed? Because apparently, if your opponent activates a GY effect that would special summon a monster, you can chain Solemn Warning as well, even though there is nothing to destroy for the "and if you do" effect.
