If the accumulated CO2 emissions into the atmosphere exceed 3,200 billion tons, the temperature rise cannot be controlled within 20 degrees by the end of this century. Some scientists believe that, in order to achieve the goal of controlling the temperature rise within 20 degrees, it is not enough to limit CO2 emissions. We must carry out large-scale atmospheric CO2 recovery operations in the world to effectively control and alleviate the degree of air pollution.
