Scientists have long been trying to establish the causes of a sharp cold snap, that happened on Earth in the XVI century, why this period even called small glacial. This would allow a better understanding. modern processes taking place with climate on our planet.
Researchers at University College London came to an interesting conclusion: the cause of small glacial the period was, in their opinion, the discovery of America by Columbus (1492), after which crowds of European colonialists poured here and began genocide of the local population. As a result, millions of Aboriginal people were killed or died out from diseases brought by Europeans. So to the beginning of the XVI century in the territory of modern USA the number of local population declined by 90 percent. And this, scientists say, it was enough for it to be “launched” on the whole Earth ice Age. The fact is that 60-70 million Indians who lived in pre-Columbian America, used vast areas under arable land and meadows, and when the aborigines died, quickly grew on this earth young forest. Its total area was approximately 550 thousand square kilometers is a tenth of all the forests of the Amazon. The newly-found vegetation needed a tremendous amount carbon dioxide, which was consumed from the atmosphere, as a result of what global cooling has come on the planet. Today we We observe the opposite process: excess carbon dioxide causes noticeable warming. To deal with excess CO2, we should or plant an area the size of Texas in a forest, or somehow cut carbon dioxide emissions.
After reviewing the findings of British scientists, the world climatologists and forecasters found them quite interesting, but not certain. If everything in nature happened so unambiguous and straightforward, then humanity is constantly increasing in number and destroying more and more forests for sowing area, would have long brought the planet to a global catastrophe. However this has not yet happened. But there are others, for example man-made factors of negative impact on the Earth’s climate, perhaps no less serious than massive deforestation.
It turns out that the so-called small ice age due to some other reasons that are not yet known to us, for example, due to the eruption of supervolcanoes (there is even a fantastic theory that an atomic war took place on Earth at that time). Therefore with confidently say that the current “global warming” (which for some reason looks more like cooling) is due to “dominance” in the atmosphere of carbon dioxide, still not worth it …
