Cabo Verde Volcano

On his first-ever expedition to Siberia, George witnesses the alarming effect of melting permafrost, visits a 12,000-year-old dog, and camps out with reindeer herders on the chilliest night of his life.

George crisscrosses Laos to witness a nation entering the modern world. He comes across ancient farming techniques, visits a conservation center that provides elephants a new way of life, explores an abandoned cave city, and paddles an underground river that holds some timely secrets.

George heads to the iceberg capital of the world — Newfoundland, Canada — for an up-close look at these floating giants from above, from below, and from the very top of a frozen mountain on the move.

Ground zero for climate change and literally at risk of being wiped off the map, George is in Bangladesh during monsoon season to see how resilient and creative locals are adapting to their increasingly hostile environment.

The world’s largest land predator is under threat, and George is heading to Canada’s far north to see how polar bears are coping with their rapidly changing climate.
