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.

20世纪末至21世纪初大气表层二氧化碳浓度的增长率

摘要

考虑了20世纪末和21世纪初不同地理位置的大气表层中CO ₂浓度的变化率。使用了GAW（全球大气监测）监测站的月平均浓度系列。 在上述两个时间段内，估计有64个站点的平均CO ₂浓度增长率及其标准偏差。结果表明，在分析期间，增长率随纬度的变化很小。但是，第二阶段几乎每个站点的增长率都大大超过了第一阶段的值。因此，全球范围内的CO ₂加速增长 尽管国际社会为减少全球人为排放量做出了努力，但集中度仍在增长。
