After one of the hottest years on record, Sir David Attenborough looks at the science of climate change and potential solutions to this global threat. Interviews with some of the world’s leading climate scientists explore recent extreme weather conditions such as unprecedented storms and catastrophic wildfires. They also reveal what dangerous levels of climate change could mean for both human populations and the natural world in the future.

For 170 years, a Native American community has occupied Isle de Jean Charles, a tiny island deep in the bayous of Louisiana. They have fished, hunted, and lived off the land. Now the land that has sustained them for generations is vanishing before their eyes. Coastal erosion, sea level rise, and increasing storms are overwhelming the island. Over the last fifty years, Isle de Jean Charles has been gradually shrinking, and it is now almost gone. For these Biloxi-Chitimacha-Choctaw Indians, their land is more than simply a place to live. It is the epicenter of their people and traditions. They now must prepare to say goodbye to the place, where, for eight generations, their ancestors cultivated a unique part of Louisiana culture.
