Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. pollution is falling, harmful ground-level ozone pollution is on the rise, especially in large cities. There was so much particulate matter in Chinese cities that it stunted the ozone production.

Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. The findings associated ozone exposure with markers of platelet activation and increased blood pressure.

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. The climate effects of hydrogen have been an under-researched topic.
