It's hard to say who was more condescending here, Our Lady of the Magic Dolphins, or Face the Nation host John Dickerson. Never mind that, as Media Matters recently reported:

But the U.S. Department of Defense, the G7 Council on Foreign Relations, the Center for Naval Analyses Military Advisory Board, and many other military experts agree that climate change a top national security threat. In fact, the Department of Defense's 2014 Quadrennial Defense Review stated that climate change impacts, such as resource scarcity and severe weather, are "threat multipliers" that will create conditions that can "enable terrorist activity." That's one reason why the Pentagon is already preparing for the impacts of climate change.

... Dickerson and one of his guests, Peggy Noonan, snickered and sneered at Sen. Bernie Sanders for saying that there is a link between climate change and terrorism, both during the Democratic debate on Saturday night, and again during an interview on the same show with Dickerson.

Here's the name calling the audience was treated to by Noonan: WSJ's Peggy Noonan Says Bernie Sanders Looked "Daffy" By Linking Climate Change And Terrorism:

PEGGY NOONAN: Working against him was -- I believe, the fact that last night and more strikingly today on your show -- Bernie Sanders essentially said a major problem with all of this ISIS stuff and terrorism and what's going in the West is climate change and global warming. Which makes him -- to many people -- look slightly daffy, like someone who doesn't understand what the real subject is, and is leaning outside to sort of leftist or progressive nostrums that he can talk about. This is about terrorism. It isn't about climate change and deserts and people migrating because it's hot.
