Disastrous hurricanes. Widespread droughts and wildfires. Pervasive heat. Extreme rainfall. Something is up with the weather, and scientists agree the trend is not just a coincidence. It's the result of the weather machine itself?our climate?which is changing, becoming hotter and more erratic. But some people are skeptical of global warming, and one-third of Americans doubt humans are changing the climate. NOVA, a production of WGBH Boston, cuts through the confusion and helps define the way forward in a special two-hour documentary: DECODING THE WEATHER MACHINE. Why do scientists overwhelmingly agree that our climate is changing, and that human activity is causing it? How will it affect us through the weather we experience, and when? And what will it take to bend the trajectory of planetary warming toward more benign outcomes? Join scientists around the globe as they explore the dynamics of the air, land, sea, and ice?the major components of Earth's weather and climate machine?and follow the innovators developing new ways to be resilient, and even thrive, in the face of enormous change.

Coral reefs are the nursery for all life in the oceans, a remarkable ecosystem that sustains us. Yet with carbon emissions warming the seas, a phenomenon called "coral bleaching"-a sign of mass coral death-has been accelerating around the world, and the public has no idea of the scale or implication of the catastrophe silently raging underwater.
