Regarding the April 20 letter, “Not scientific to declare issue settled”: I will agree with Mr. Frey about the error of declaring “settled” any scientific question under study and investigation. I would also agree that to suppress “a journalist’s opinion” (or any opinion) is not in keeping with free speech rights. However, that is as far as I can go. Opinions are not facts or evidence.
A journalist’s opinion is not scientific fact or evidence unless he/she is quoting genuine scientific information. There are no facts or evidence presented by climate change “deniers” to refute the findings of the majority of scientists who agree that climate change is occurring. So, there has been no debate, no clear argument in favor of “denying” that climate change exists. In contrast the climate scientists have an abundance of longitudinal data, facts, evidence to account for climate change. Whether the journalists are Fox News or any print media, unless they are citing evidence, there is no debate. We all know that debating opinions can’t produce anything but an agreement with, or a changed “opinion.”
