Six degrees could change the world Sanction

'Six degrees could change the world' is a National Geographic documentary, which will reveal the irreversible consequences of this phenomenon and identifies possible solutions to alleviate it. The television report will be broadcast premiere on Sunday 10 February at 21.00 hours by the National Geographic Channel. Just six degrees
less is what distinguishes the current interglacial of the last Ice Age, when Europe was practically covered with ice.
With this premise, the film asks what would happen with six grades, and details what has already happened with the rise of almost one degree and that continue to happen in successive decades until the hot six degrees under the worst case scenario by the Intergovernmental Panel on Climate Change (IPCC).
known in Spain as part of these impacts: more droughts and extreme weather. Weather migrates through the English Channel to the point that in the UK and over 400 vineyards beginning to produce wines and have even started the olive groves of Tuscany in Italy.
The report, based on the play 'Six Degrees' of journalist Mark Linas, described the scene with two degrees as a world with few insects, endangered polar bears, tundra in the agricultural process, deserts growth and coral islands under the sea.
This scenario is the most immediate in two or three decades, and it is irreversible. These two degrees more will come when the atmosphere contains 450 parts per million (ppm) of CO2, which is just around the corner when it reached 383 ppm, the highest concentration of the last million years. With three degrees
sea level could rise up to seven meters if Greenland is losing its glaciers, the second largest freshwater reserve on the planet. The Arctic will be ice free in summer, the Alps will lose its glaciers and the Himalayas will remain almost without them, endangering the needs of 2,000 million people that depend on these reserves of frozen water.
The scenario of the four grades is almost frightening and science fiction. The planet would be unrecognizable. The Amazon will be virtually no water, the rainforest would be reduced to a sheet, large rivers disappear, the fire would destroy large amounts of forests.
This process would lead to what they call in the documentary "positive feedback". That is, the drought can lead to more fires and they contribute to more drought.
With five degrees, large areas of the planet would be uninhabitable. Hundreds of millions of people will become climate refugees fleeing the heat and lack of water. The documentary considers it "unthinkable that may continue Civilization", since the whole social system would collapse. Even explode vital resource wars. And with six degrees
reach mass extinctions. "It would be a scenario that has only been conceived in the biblical Judgement Day," says a voiceover in the documentary. The scientists consulted have not been able to answer the question. However, Mark Linas announced that "the oceans would rise 70 meters level" and recalled that 251 million years ago with these temperatures, 90% of species became extinct.
