The earth threatens global catastrophe

Земле грозит глобальная катастрофа

Earth can turn into a greenhouseEven if humanity will carry out the Paris agreement on climate change, the average temperature of the Earth could still grow by another 3-4 degrees because of the changes caused by the “safe” level of warming that can run other processes which will already be hard or impossible to stop, writes the with reference to Aspects.

Temperature, therefore, can exceed the average for the last 1.2 million years, writes N+1 with reference to the journal Proceedings of the National Academy of Sciences.

Now the average global temperature of the planet by about one degree less than the pre-industrial period, i.e. the mid-nineteenth century. The Paris agreement in 2015, suggests that by limiting emissions of greenhouse gases, the temperature increase due to anthropogenic effects on climate, will not exceed two degrees Celsius is considered a relatively safe threshold at which climate change impacts are not as severe.

Will Steffen (Will Steffen) from the Australian national University and his colleagues evaluated the risk of so-called “scenario of the Earth-greenhouse” in which the average temperature on 4-5 degrees above pre-industrial levels, Global sea level by 10 to 60 m exceeds the current. “Emissions of greenhouse gases from human activity is not the only factor that determines the Earth’s temperature. Our study suggests that anthropogenic warming to two degrees Celsius can run other system processes, which can be further warming even if we cease to emit greenhouse gases,” said Steffen.

Scenario “Earth-greenhouse” is fraught, in particular, the destruction of the greater part of coral reefs and their ecosystems, risk of coastal flooding and adverse consequences for agriculture throughout the world.
