Humanity will collapse when the Earth warms 5 degrees

September 13, 2010 .- At a press conference, Lovelock has pointed out that global warming is a reality and that proof of this is the sea \u200b\u200blevel rise that occurs every year of three millimeters, "a phenomenon that can only be by increased melting in the Arctic because the increase in water temperature causes it to grow in volume.

The renowned scientist, author of the Gaia theory , considered unstoppable global warming is "inevitable" that humanity reach a climate tipping point. According to Lovelock, the man "will collapse" as a result of rising five degrees centigrade thermometer, which has been convinced that it will happen, although it is not possible to determine when.

Despite the devastating their predictions, Lovelock has not lost the smile to say that he would like to know when they reach the "point of no return", since it is impossible to know if it will happen in a century or a thousand years and in any case, the only thing man can do is "adapt."

At a press conference, the scientist pointed out that similar episodes of global warming have already happened before on Earth, so it is not surprising that recur in the future, although the current rate of warming is 25 times now specified.

From continue as at present, in 500 years could achieve that increase of five degrees, said. However, stressed that models and predictions, in many cases, contain errors of calculation.

This future scenario will involve the desertification of large tracts of land, displacement of tropical forests into colder latitudes, melting the poles, where crocodiles may live again has ironized Lovelock, "and the consequent mass migration in search of habitable zones.

As an example of the "inevitable" and the truth of this heating process progressive, recalled that the sea level continues to grow at an average of 3 millimeters each year, another side effect that is warming.

Among the recipes for human adaptation, Lovelock has stressed the need to also use atomic energy "argument based on the low emission of CO2 that industry, which already earned him criticism from environmental groups - as well as solar energy and natural gas, among other energy sources.
