The air of our planet are contaminated for 300 years

Humanity could change the climate, that its restoration will be needed century, say scientists. In order for the climate of the planet back to the figure in the 20th century, you will need a few hundred years, say experts. Climatologists think that the favorable scenario can be only in case, if humanity is to extract from the atmosphere the carbon dioxide that industry were thrown throughout the 20th century.

 




"Emissions associated with human activity totaled about 8 billion tons of CO2 per year, half of this amount remained in the atmosphere, the ocean absorbs the rest and communicates in other ways. To return to the climatic conditions of the 20th century, we need to remove from the atmosphere more carbon dioxide than was released originally," — says Andrew McDougall of Canada's University of Victoria.

 




Climatologists believe that since 1910 the average temperature on earth increased by one degree. This means a huge increase in the total amount of thermal energy that is in the atmosphere and oceans. According to experts, the probability of a hot summer in a particular area over the last 50 years increased by 5 times.
