Bill McKibben, who first warned of climate change 30 years ago, says its effects are now upon us. He talks about heat waves, fires, flooding, drought, and, soon, millions of climate refugees. "The idea that anybody's going to be immune from this anywhere is untrue," he says. His new book is 'Falter.'

Also, Ken Tucker reviews The Mekons' new album 'Deserted,' their first in 8 years.
