Ade starts his odyssey into the climate crisis in the Solomon Islands, where he witnesses tracts of land that have now vanished due to rising tide levels. At the Great Barrier Reef one of the more astonishing climate change stories emerges: the sex of green turtles is determined by temperature and, as the area gets hotter, 99% of the hatchlings are female. Is the entire species now doomed?

The low-lying country of Bangladesh has always been vulnerable to the encroaching sea. But as Ade Adepitan discovers, climate change is swamping farms and destroying livelihoods. Mangrove trees could provide a natural solution, but is it too little too late? In Bhutan, melting Himalayan glaciers affect the entire planet, but does the country becoming carbon negative offer a solution?

Ade Adepitan visits the frozen islands of Svalbard near the Arctic and sees how winter temperatures have risen by an astonishing amount in recent years. The Danish capital Copenhagen has pledged to be carbon neutral by 2025, but will eating insects, cycling and using peat to absorb carbon be enough? Finally Ade meets Greta Thunberg to find out how the young generation is determined to save us all.
