| Abstract: | The rate of variations in the CO2
concentration in the atmospheric surface layer at different geographic
locations in the late 20th century and early 21st century is considered.
The series of monthly mean concentration at the GAW (Global Atmosphere
Watch) monitoring stations are used. The average rates of CO2
concentration growth and their standard deviations are estimated for 64
stations for the above two time periods. It is shown that the growth
rate insignificantly varies with latitude during the analyzed periods.
However, the growth rate for almost every station in the second period
substantially exceeds the value for the first period. Thus, there is a
worldwide acceleration in the CO2 concentration growth
despite the international efforts on the reduction of global
anthropogenic emissions. |
