Decoding the Weather Machine Trailer
Disastrous hurricanes. Widespread droughts and wildfires. Withering heat. Extreme rainfall. It is hard not to conclude that something’s up with the weather, and many scientists agree. It’s the result of the weather machine itself—our climate—changing, becoming hotter and more erratic. In this 2-hour documentary, NOVA will cut through the confusion around climate change.
