Explanation:

When you have a conjunctive adverb linking two independent clauses, you should use a semicolon. In the sentence, you have two independent clauses connected by the conjunctive adverb therefore (1 & 2), so a semicolon should be placed before this word. What is more, a comma is placed after it because the conjunctive adverb is in inital position in the sentence.
