Kyle Pope, the editor of Columbia Journalism Review, tells Brian Stelter about the Covering Climate Now coalition, which CJR is spearheading with The Nation. Pope says that about 250 news outlets around the world have committed to a week's worth of focused climate change coverage in the run-up to the UN Climate Action Summit on September 23. He says it "could end up being the most extensive effort ever to sort of organize the world's press around a single topic." Pope and Stelter discuss strides made in the news media in tackling the topic; the critical role of local meteorologists; and a "generational divide in the way people consume this news."To learn more about how CNN protects listener privacy, visit cnn.com/privacy
