Mr. Esler is teaching that correlation proves causation, similar to the "scientific method" used in the Middle Ages in Europe when the existence of a witch was proved when misfortunes occured at the same time someone unlikeable moved into the neighborhood.  Is he teaching these kids how this climate change is different from all the other times the climate changed on this planet and how the use of fossil fuels can be proven to be the exclusive cause of this change?  Perhaps the title of this piece should have been "How to brainwash kids into believing your theory is a fact".
