In a groundbreaking expedition on Mount Everest, dozens of scientists converge to investigate what secrets the world’s highest peak has to tell us about our changing climate. The notorious Khumbu Glacier is mapped in stunning detail, biologists study extreme lifeforms, and a team of Sherpas and climate scientists climb straight toward the “death zone” to install the highest weather station in the world.

From the mighty Amazon’s icy source to its plume reaching as far as the Caribbean, National Geographic Explorer teams conduct groundbreaking research to take the pulse of one of the planet’s integral and endlessly magical resources. From the health of river turtles and pink dolphins to the migration of Andean bears, extreme urgency is met by equally hopeful solutions.

In the heart of Uganda, there are lion prides that spend much of their lives in the trees – a rare and mysterious behavior seen in few other places in Africa – and little is known about why they do it. Big cat biologist Alexander Braczkowski sets out to study these lions, and his journey takes an unexpected, emotional turn.

Outside the Sudanese capital Khartoum, the remains of an ancient city stand in the desert. Are you ready to dive beneath the pyramids of Sudan's black pharaohs?
