The Earth will lose one third of animal species because of climate changes, scientists warn

Global warming poses an existential threat to one third of animal species and to a half of plant species. The Earth may lose fifty thousand species even in this century unless the governments change quickly their attitude and begin fast to restrict greenhouse gas emissions.

This warning was introduced by scientists from Great Britain, Australia and Colombia in a report published in specialist magazine Nature Climate Change. Among the most endangered animal groups there belong reptiles and amphibians. The most threaten areas are then Australia, sub-Saharan Africa, Amazonia and central America.

By the year 2080, unless anything changes, 57 per cent of flora and 34 per cent of fauna will have lost more than a half of the areas of their natural environment because of climate changes. Only four per cent of animals should do better thanks to climate changes. Plants will be worse off all. The scientists consider their estimate to be very moderate. They did not involve other influences, as pesticides or illnesses, into their model.

The hope for the change of this unfavourable trend is still alive. If the governments saw that the greenhouse gas emissions into the atmosphere would culminate in 2016 and they would decrease permanently after that, the estimated damage would lower of 60 per cent. In case the emissions grow until 2030 and then they start to decrease, the damage will be lower of 40 per cent contrary to the prognosis.

However, there are still too few signals of an optimistic scenario. In May there was measured the highest concentration of  carbon dioxide in the atmosphere  ever in modern history. Station Mauna Loana in Hawaii measured the value of 400 ppm for the first time in the history. At the beginning of the Industrial revolution though the concentration of CO2 in the atmosphere reached the value of about 280 ppm, in 1959 station Mauna Loa measured already the concentration of 316 ppm.

“Mass dying out would be a tragedy not only for the nature, but mainly for human. The governments therefore have to make all the effort to prevent this catastrophe,“ commented the research results Dalibor Dostal, the director of the European Wildlife conservation organisation.
