冠状病毒的封锁改善了空气质量

Coronavirus lockdown leads to improved air quality

Efforts to curb the spread of coronavirus pandemic have slashed economic activity and resulted in localised improvements in air quality, the World Meteorological Organization (WMO) has said.

世界气象组织(WMO)表示：遏制冠状病毒大流行蔓延的努力大幅削减了经济活动，并使局部地区的空气质量得到改善。

However, it is too early to assess the implications for concentrations of greenhouse gases that are responsible for long-term climate change. That is because carbon dioxide levels at key observing stations have so far this year been higher than the previous one.

然而，现在评估温室气体浓度对长期气候变化的影响还为时过早，这是因为今年到目前为止主要观测站的二氧化碳含量一直高于前一年。

In its statement on Friday, the WMO stressed that any cuts in emissions as a result of the economic crisis triggered by the pandemic are not a substitute for concerted climate action.

世界气象组织在周五的声明中强调，任何由大流行引发的经济危机导致的减排措施都不能替代协调一致的气候行动。
