Air Pollution expected to Cause 60,000 Deaths in 2030 and 2,60,000 in 2100 Globally: Study

According to the study, hotter temperatures speed up the chemical reactions that create air pollutants like ozone and fine particulate matters, which impact public health

  • Air pollution, if left unaddressed, is expected to increase air pollution-related deaths by nearly 60,000 in 2030 and 2,60,000 in 2100 globally
  • Locations that get drier may also have worse air pollution because of less removal by rain and increased fires and windblown dust
  • The team used an ensemble of several global climate models to determine the number of premature deaths that would occur due to ozone and particulate matter in 2030 and 2100

New York, August 2, 2017: Air pollution, if left unaddressed, is expected to increase air pollution-related deaths by nearly 60,000 in 2030 and 2,60,000 in 2100 globally, a study has claimed.

According to the study, hotter temperatures speed up the chemical reactions that create air pollutants like ozone and fine particulate matters, which impact public health.

Locations that get drier may also have worse air pollution because of less removal by rain and increased fires and windblown dust. As trees respond to higher temperatures, they will also emit more organic pollutants, the researchers said.

“As climate change affects air pollutant concentrations, it can have a significant impact on health worldwide, adding to the millions of people who die from air pollution each year,” said lead researcher Jason West, Associate Professor at the University of North Carolina at Chapel Hill.

For the study which appeared in the journal Nature Climate Change, the team used an ensemble of several global climate models to determine the number of premature deaths that would occur due to ozone and particulate matter in 2030 and 2100.

For each model, the team assessed the projected changes in ground-level air pollution that could be attributed to future climate change. They then overlaid these changes spatially on the global population, accounting for both population growth and expected changes in susceptibility to air pollution.

Five out of eight models predicted there will be more premature deaths in 2030, and seven of nine models in 2100.

“Our finding that most models show a likely increase in deaths is the clearest signal yet that climate change will be detrimental to air quality and health,” West noted.

In addition to exacerbating air pollution-related deaths, climate change is expected to affect health through changes in heat stress, access to clean water and food, severe storms and the spread of infectious diseases, the researchers said. (IANS)

The Mayors of Paris, New York, Los Angeles and Copenhagen on Friday announced their support for the global climate strike.

“Today, September 20th, these inspiring young leaders have called for adults to join them for a global climate strike. We have an opportunity to show, not only that we hear their message, but that they have inspired us to act even faster,” they said in a joint statement.

“As mayors, our greatest responsibility is to protect the lives and wellbeing of those that live in our cities. As adults, our obligation is to leave the world in a better state for our children than we inherited it,” they said.

“That is why we are supporting the global climate strike. Mayors around the world, working through C40 Cities, are committed to deliver on the Paris Agreement and taking action to peak their emissions as our cities already have and bring them down sharply by 2030.

“Many businesses, investors, labour groups, faith leaders and local communities share our urgency…Young people are telling us that the climate emergency demands an emergency response. We couldn’t agree more,” the Mayors added.

They are the Mayor of Paris and Chair of C40 Cities, Anne Hidalgo; Mayor of New York City, Bill de Blasio; Mayor of Los Angeles, Eric Garcetti; and Lord Mayor of Copenhagen, Frank Jensen.

Following next week’s UN Climate Action Summit, these four leaders will be among 70 plus Mayors committing to more ambitious climate action at the C40 World Mayors Summit in Copenhagen on October 9-12.
