Professor Iain Stewart uncovers the mysterious history of Australia, and shows how Australia's journey as a continent has affected everything from Aboriginal history to modern day mining, and even the evolution of Australia's bizarre wildlife, like the koala.
Volcanoes have a fearsome reputation. In reality, they are the most important force in the creation of the planet as we know it today. Iain abseils into a lava lake and cave dives in a cenote to show how the heat that fuels volcanoes also drives some of the most fundamental processes on the planet.
As scientific studies confirm sea level changes throughout the globe, major coastal cities like Miami are now fighting back against these rising tides, before it's too late. Parts of Miami Beach are under serious threat, with major economic and social dangers looming large.
All over the world, scientists are discovering traces of ancient floods on a scale that dwarfs even the most severe flood disasters of recent times. What triggered these cataclysmic floods, and could they strike again? In the Channeled Scablands of Washington State, the level prairie gives way to bizarre, gargantuan rock formations: house-sized boulders seemingly dropped from the sky, a cliff carved by a waterfall twice the height of Niagara, and potholes large enough to swallow cars. Like forensic detectives at a crime scene, geologists study these strange features and reconstruct catastrophic Ice Age floods more powerful than all the world’s top ten rivers combined. NOVA follows their efforts to uncover the geologic fingerprints of other colossal megafloods in Iceland and, improbably, on the seabed of the English Channel. There, another deluge smashed through a land bridge connecting Britain and France hundreds of thousands of years ago and turned Britain into an island for the first time. These great disasters ripped through terrain and transformed continents in a matter of hours—and similar forces reawakened by climate change are posing an active threat to mountain communities throughout the world today.
From the global perspective of space, this 2-hour special reveals the breathtaking extent of our influence, revealing how we’ve transformed our planet and produced an interconnected world of extraordinary complexity. A journey through 12,000 years, Humanity from Space shows how seemingly small flashes of innovation have changed the course of civilization; innovations that touch all of us today in ways unimaginable to our ancestors. And we’ll gaze into the future at the new challenges we’ll face in order to survive as our global population soars because of our success. In every case we’ll look at our progression in a unique and surprising way, revealing unforgettable facts and "who knew?" connections. To visualize these stories cutting-edge technology is used to turn raw data into authentic moving images, building on expertise from a previous (and highly-praised) project; "Earth From Space." Using this technique, we can map humanity’s behavior in stunning, never seen before detail, revealing how our civilization grew, how it works today and what the future might hold.
