Ade begins in the Solomon Islands, and then travels down the east coast of Australia - from the Great Barrier Reef to Tasmania. He learns about the 'feminisation' of green turtles, bush-fires and Tasmania's renewable energy revolution.
Ade joins the effort to plant huge new areas of the Ganges delta in Bangladesh with mangroves. In Bhutan, he hears how local people are being affected by climate change but also how the nation is carbon negative.
As Ade travels across Scandinavia, he learns about winter temperature rises, sees Copenhagen's attempt to go carbon neutral and meets someone preparing for the Apocalypse in a Swedish forest and then meets Greta Thunberg.
