Meteorological Organization: Heat waves will cause more air quality to harm human health

Xinhua News Agency, Geneva, September 7th (Reporter Liu Qu) The World Meteorological Organization issued a report on the 7th that it is expected that the frequency, strength and duration of the heat waves in the century will increase, which will lead to the increase in wildfires. And ecosystem.

The "2022 Air Quality and Climate Bulberry" released by the Meteorological Organization revealed the close relationship between air quality and climate change. "With the warming global warming, even under low emissions, wildfire and related air pollution said. , Also affect the ecosystem. "

Tallas said that in the heat waves in Europe and other places this year, it can be seen that stable high -pressure atmosphere conditions, sunlight and low wind speed have led to high -level pollution. "This is a preview of the future, because we expect the frequency, strength, and duration of the heat waves to further increase, which will lead to worse air quality. This phenomenon is called 'climate punishment'."

"Climate punishment" refers to the magnifying effect of climate change on ground oxygen, which will adversely affect the air of people's breathing.

The Special Committee of the United Nations Intergovernmental Climate Change had previously evaluated reports that in the case of high emissions of greenhouse gases, the probability of disaster wildfire incidents may increase by 40%to 60%at the end of this century; %To 50%. If greenhouse gas emissions are still high, global temperatures will be 3 degrees Celsius higher than before industrialization. At that time, the level of ozone levels in some severe pollution areas will rise.
