That would only be the case if 'cultural' was being used as an adjective in the statement in question.

But no. Cultural phenomena is a well known phrase that has become a clause due to the connotations that are present when those words combine being more than the sum of each word's connotations.

You always refer to a clause as a singular even if one of the words in the clause happens to be plural. I can't be any clearer about it than that.
