The air temperature reached the highest levels in the last 4,000 years, according to scientists who say they have made these measurements and predict that in the coming decades earlier heights temperatures will be defeated.
Previous studies that have measured a period of 1,500 years ago, have suggested that the rapid increase in temperature that occurred in the last century, and which is believed to be the result of human activity, has exceeded the temperature record heat the air during this period.
New research has also confirmed that the modern warming is happening to us in recent years, is unique in that period of time.
Scientists claim that our planet will be hectic as it was during the hottest periods of modern geological era known as "Holocen", and perhaps could be even warmer than that.
This period began 12,000 years ago, when the sun caused the melting of the ice shield along the entire northern hemisphere. Scientists believe that the mild climate during the Holocene has led to the growth of human civilization around 8,000 years ago and continues to hold it, because the same diversity promotes the growth of food around the globe.
After this period, the temperature was stabilized, and then came the heating period, which lasted for 5,000 years, said according to a study published in the journal "Science, Shaun Marcotte" in the United States.
After this period, began cooling period in which the Vikings who settled in Greenland were dead zone. However, all this has happened under the influence of natural factors on which various plants and beasts have managed to adapt.
If they still will have influence on the global climate, after several thousand years, the Earth will get back to the ice age.
However, scientists now believe that this will not happen to us, due to a large ice effect that will stop it
