South America is seeing a record number of wildfires

South America is seeing a record number of wildfires, and a smoky haze hung in the air in cities like São Paulo this week. The World’s Carolyn Beeler reports from western Brazil, where climate change is fueling unprecedented flames in the Pantanal wetlands. Plus, video has emerged of North Korea’s Kim Jong-un touring a uranium enrichment facility. Analysts say these images will help experts estimate with more accuracy how much nuclear capability North Korea has achieved. And a new book from Atlas Obscura compiles delightful stories of the living creatures whose behavior ranks right up there with the wonders of the world.
