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 last 10 years were the hottest decade ever measured on Earth, last year was the second warmest ever and NASA says “you haven’t seen anything yet.”

The National Oceanic and Atmospheric Administration said Wednesday that the average global temperature in the 2010s was 14.7 degrees Celsius, with eight of the 10 hottest years ever recorded.

Parts of Africa, Asia, Australia, Europe and South America had record-high temperatures in 2019. Alaska’s average temperature was above freezing for the first time in recorded history.

Many climate scientists who have seen the study said there was no other explanation for the record-breaking warming than human activity.

“This is going to be part of what we see every year until we stabilize greenhouse gases,” said Gavin Schmidt, head of NASA’s Goddard Institute for Space Studies. “We crossed over into more than 2 degrees Fahrenheit warming territory in 2015 and we are unlikely to go back. This shows that what’s happening is persistent, not a fluke due to some weather phenomenon.”

Experts say natural causes of a warmer atmosphere, including more heat from the sun and climate variations, are not big enough to explain the long-term temperature rise.

For those who still question global warming, the scientists say all one has to do is look at melting ice sheets, more powerful storms, floods in some parts of the world and drought in others as clear evidence. (VOA)
