Climatologists from the Intergovernmental Panel on Climate Change (IPCC) have concluded that an increase in global temperature by even 1.5 degrees Celsius will lead to serious climate change, the disappearance of natural ecosystems and the extinction of many species. This was announced in a press release on Phys.org.
It is believed that a warming of the Earth's climate by two degrees will cause unpredictable changes in the atmospheric circulation system. There will be intense melting of glaciers, which in turn will lead to a rise in sea levels. It is estimated that if the warming trend continues by 2100, coastal megacities will flood and some inhabited islands, including the Maldives, will disappear.
Therefore, the international Paris agreement of 2015 provides that humanity should not allow an increase in the average temperature of the planet by more than 1.5 degrees.
In the new work, climatologists have shown that even with successful containment of warming, there are significant climatic risks for certain regions of the planet. In addition, it is important how exactly the required indicator will be achieved. If the rise in the average temperature for some time exceeds 1.5 degrees and then drops to the desired value, then this will likely lead to irreversible damage to the biosphere, including the extinction of many species. However, many scenarios provide that the average temperature will indeed exceed the limit for some time.
Climate cooling measures include planting forests and other methods to reduce the concentration of carbon dioxide in the Earth's atmosphere. At the same time, a number of experts often talk about the need to switch to alternative forms of energy, including the use of biofuels. However, scientists believe that the only effective way to prevent a rise in temperature is to drastically and quickly reduce carbon dioxide emissions.
In 2017, experts came to the conclusion that humanity must reduce emissions by 2020. In 2016, scientists at Harvard University said that the rise in temperature is happening too fast to be stopped by reducing greenhouse gas emissions.
