Six degrees could change the world...A new documentary titled “Six Degrees Could Change the World” (now above) will be airing on the National Geographic Channel on Sunday 10 February at 8pm ET.

The program, based on a book by the same title by Mark Lymas, sounds like scenes from a dramatic “The Day After” style disaster movie: from 1 degree of temperature increase: “residents flee Midwest drought” “alpine villages threatened by frequent rockfalls” “mass bleaching of coral spreads, scientists warn of ecological impact” “hurricane expected to hit Mediterranean coast”… to 6 degrees of temperature increase: “emergency alert system disbanded” “communications sporadic as major infrastructures collapse” “ocean’s surface becomes poisonous” “cities and towns unsustainable”….

The book and documentary are based on the estimation that, during the last 100 years, global warming has increased by about .07 degrees Celsius or 1.2 degrees Fahrenheit. According to the UN Intergovernmental Panel on Climate Change (IPCC), at no other time in the past 1,300 years has our planet been as warm as it is now. Temperature records from the deep ocean suggest that temperatures are now within a degree of their highest levels in 1 million years.

The IPCC estimates that Earth will continue to increase in temperature between 1.4-5.8 degrees Celsius by the end of this century. Though six degrees doesn’t sound like a lot, it’s enough to alter the world as we know it in a devastating way. Much of life will be destroyed. The signs are already there — the snows of Kilimanjaro are melting, glaciers on the Matterhorn in the Alps are melting and releasing huge boulders, and atoll nations in the Pacific are disappearing inch by inch under the water as it rises due to global warming.

This documentary and book describe in vivid detail what will happen if global warming continues unchecked. Check them out! Sunday 10 February at 8pm ET (or watch it above).
