I agree with Dita McCarthy's "Lies outrace truth about climate change" letter (March 23), and I would like to add a few footnotes:
-- Not only is the global warming contest similar to the tobacco/cancer debate of many years ago, but -- as referenced in the book "Merchants of Doubt" by Naomi Oreskes and Erik M. Conway -- most of the deniers are the same people.
-- Mr. Duckett's statement that arctic ice is increasing is patently false. Satellite photos show the ice cap size decreasing since observation began in 1979. The rate of decline has increased since 2000, and 2015's ice coverage was at a record low.
I also agree that the Sun Herald could do better. Both sides of an issue is good policy when the issue is a matter of opinion, but it becomes a disservice when it presents opinion versus fact.

There are still people who believe the Earth is flat and that we never put men on the moon. I don't think their "opinions" merit publication.
