Climate change is arguably the defining challenge of our time, yet misunderstanding and misinformation has hampered the public’s ability to understand the science.

In this 2-hour documentary, NOVA will cut through the confusion to explore why scientists overwhelmingly agree that our climate is changing, and that human activity is causing it.

Decoding The Weather Machine: Prologue

Discover how Earth’s intricate climate system is changing.

How will it affect us through the weather we experience, and when?

Join scientists on the quest to better understand the workings of the weather machine we call Earth, and how we can be resilient in the face of change.
