Meet Dr. André Fenton, the co-host of NOVA Wonders.

From singing whales and squeaking bats to thumping spiders and clicking dolphins, the world is filled with the exotic sounds of our fellow creatures. What are they saying? Can we decode their own communications? NOVA Wonders follows researchers around the globe who are deciphering an amazing array of clues that reveal how animals share information critical to their survival.

NOVA Wonders takes viewers on a journey to the frontiers of science, where researchers are tackling some of the biggest questions about life and the cosmos. From the mysteries of astrophysics to the secrets of the body to the challenges of inventing technologies that could rival—and even surpass—the abilities of the human mind. These six hours reveal how far we’ve come in our search for answers.

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.

Ecologist Stephen Pacala says a climate change conspiracy is impossible.
