Synopsis
The litany of disasters reads like the Apocalypse: melted ice caps, submerged coastal cities, prairies turned to deserts. Mass extinctions.
This worst case scenario is not merely a prophecy or work of fiction. It is a very real possibility that may loom in our not too distant future. But how likely is this outcome, what will bring it about and can it be avoided?
To answer these imperative questions, The History Channel applies its renowned expertise and authority to the issue of global warming in this very special feature-length documentary.
A Global Warning? spans the globe and 14 extreme locations in all to survey the frontline of scientific research and climatic impact.
Meet with scientists unearthing evidence of our planet's ancient weather history, how crocodiles may have once roamed the Arctic and with experts analyzing humanity's ever-expanding footprint.
Understand, with the help of exacting animations, how sun activity, volcanic eruptions, meteor impacts, and even continental drift have made huge differences in the Earth's weather systems.
Without shrinking from the inconvenient truths, The History Channel investigates the most dramatic climatic events in Earth's past and considers the future trends that will decide the fate of our species.
