中国社会科学院、中国气象局联合发布的《气候变化绿皮书：应对气候变化报告(2013)》(以下简称“绿皮书”)指出，近50年来中国雾霾天气总体呈增加趋势。其中，雾日数呈明显减少，霾日数明显增加，且持续性霾过程增加显著。
Report: Climate change worsens smog
Smog brings notable negative effects to the climate, environment, health and economy, according to a new report calling for greater attention to the problem and effective measures to control it.
Citing historical data analysis, the Annual Report on Actions to Address Climate Change 2013, which was released Monday by the Chinese Academy of Social Sciences, said that China has seen smog with increasing frequency and duration over the past 50 years.
The report noted that smoggy days have increased, particularly in the Yangtze River Delta, a key economic region encompassing Shanghai and parts of Jiangsu and Zhejiang provinces, as well as in southern Guangdong's Zhujiang River Delta, which is adjacent to Hong Kong and Macao.
The report stressed that increased air pollutants caused by growing social consumption of fossil fuels were the main cause of the worsening smog, adding that photochemical pollution and cooking and vehicle emissions also contributed to the phenomenon.
According to the report, more frequent smoggy weather is likely to induce extreme climate incidents, hinder air, water and land traffic due to low visibility, affect lung functions and the human immune system, and lead to more deaths and severe chronic diseases.
"Huge economic costs are lurking behind all these influences," said the report.
While encouraging China to draw experiences from other countries, the report stressed that the country must map out a plan to combat air pollution based on its own situation and conditions.
"Addressing air pollution and reducing smog requires long-term attention and actions from all walks of life," the report added.
