Gradual increase in temperature on the planetThe land entails many negative consequences, including the extinction of certain animal species and the unsuitability of some of the now fertile lands for further living. However, scientists from the Krasnoyarsk Scientific Center of the Russian Academy of Sciences and the NASA Research Center have found that global warming can revive such harsh and low-habitable places like Siberia. It is possible that at the end of the XXI century many more people will live in this territory than now.
Currently living in Siberiaonly 27% of the inhabitants of Russia. This is due to the fact that the average temperature in this region rarely exceeds zero degrees, and 65% of its area is occupied by permafrost, unsuitable for growing crops. Also in Siberia there is relatively little rainfall, which also creates unfavorable conditions for life.
Siberia will be suitable for life
To learn how to gradually increasetemperature will affect the region with harsh conditions, scientists have considered two scenarios. The first was called RCP 2.6 - the researchers suggested that humanity will reduce the amount of carbon dioxide emissions into the atmosphere, and the temperature rise will occur slowly. The second scenario, called RCP 8.5, implies that emissions will increase and warming will occur more intensively.
Based on these scenarios, the researchers didvery interesting calculations. So, if humanity takes seriously the reduction of emissions into the atmosphere, by the end of the XXI century, the average January temperature in Siberia will increase by 3.4 degrees, and the July temperature - by 1.9 degrees Celsius. If emissions increase, the January temperature will increase by 9.1 degrees, and the July temperature - by 5.7 degrees Celsius. The average amount of precipitation will increase by 60-140 millimeters.
The population will increase in Siberia
It turns out that in any case, by the end of the centurySiberia will become a more hospitable place with moderate temperature and humidity. If now permafrost covers 65% of the territory, then by 2080 only 40% of it will remain. Theoretically, thanks to all these favorable factors, the population in Siberia will increase by as much as five times.
The authors note that the habitability of Siberia will increaseonly if the population increases in Russia. At the moment, demographers believe that during this century, this figure will be reduced by 1.5 times.
However, until 2080, humanity may notlive - so, at least, considers the Australian analyst Breakthrough. According to experts, civilization is already on the verge of self-destruction, and the critical point will be reached in 2050. You can read more about this in our material.
