The text is the original version of the speech given by actor and film producer Leonardo DiCaprio in 2014 at the obligatory climate conference at the United Nations.

As he is not a scientist himself, he seeks knowledge about the climate phenomenon from other individuals who in this case are scientists, which means that he makes use of the form of appeal logos. This is used when appealing to recipients’ common sense.
Leonardo DiCaprio is occupied by the topic, and the receivers feel his personal commitment as he chooses to use pathos with the intention of getting the reader or listener to be emotionally influenced.
