Recent spills in West Virginia and North Carolina cast a spotlight on toxic hazards in our midst. But as bad as they are, these acute incidents pale in scope compared to the chronic flow of hazardous chemicals coursing through our lives each day with little notice and minimal regulation.

John Oliver hosts a mathematically representative climate change debate, with the help of special guest Bill Nye the Science Guy.

“This figure shows how annual average temperatures in the contiguous 48 states have changed since 1901. Surface data come from land-based weather stations. Satellite measurements cover the lower troposphere, which is the lowest level of the Earth’s atmosphere. “UAH” and “RSS” represent two different methods of analyzing the original satellite measurements. This graph uses the 1901–2000 average as a baseline for depicting change. Choosing a different baseline period would not change the shape of the data over time.” – United States Environmental Protection Agency
