 NPR's Lauren Summer reports it continues a streak of record-breaking months. Temperatures globally in June were more than 2 degrees Fahrenheit hotter than average. That makes it the hottest June since record-keeping began in 1850, according to the National Oceanic and Atmospheric Administration. It's also the 13th month in a row of record-breaking temperatures. Federal officials say that's due to both climate change and the El Nino weather pattern, which is now ending.
