A study by researchers from the International Institute for Applied Systems Analysis (IIASA), published in The Lancet, concluded that extreme heat caused by climate change has lost up to 153,000 million hours of work during 2017 all over the world.
According to the report in the Lancet Countdown: Monitoring Progress in Health and Climate Change, 157 million more vulnerable people suffered heat in 2017 than in 2000, and 18 million more than in 2016. China alone lost 21,000 million hours, equivalent to annual employment for 1.4 percent of its active population. India lost 75 billion hours, equivalent to 7% of its total active population.
The report draws attention to this the rise in temperature due to climate change expose the company to "unacceptably high" health risk, and warns for the first time that older people in Europe and the Eastern Mediterranean are "particularly vulnerable" to extreme temperatures.
This suggests that the risk in Europe and the eastern Mediterranean stems from the aging population living in cities, with 42 and 43 percent of those over 65 being at risk of heat. In Africa, it is estimated that 38 percent are vulnerable, while Asia is 34 percent.
The study also emphasizes that air pollution has caused several million premature deaths due to fine particles worldwide in 2015, the conclusion of IIASA scientists confirming previous research.
Primary doctors, academics and public order experts from 27 organizations contributed to the analysis and are the authors of the report. Along with IIASA, research partners include the World Bank, World Health Organization (WHO), University College London (UK), and Tsinghua University (China).
Half a million deaths from coal
The IIASA researcher, Gregor Kiesewetter, led the team from the research program on air pollution and greenhouse gases, which estimated the risk of air pollution to human health. They estimate it only coal represents 16% of premature deaths related to pollution, around 460,000.
Great benefits for indoor air pollution come from the residential sector, mainly from solid fuels such as biomass and coal. Industry, electricity generation, transport and agriculture are also important contributors. "Distribution shows that, unfortunately, a single sector or fuel approach does not solve the problem. Air pollution is a multifaceted problem that requires integrated strategies that cover many sectors that will vary from country to country, "says Kiesewetter.
On the other hand, the study has shown that heat significantly aggravates air pollution in urban areas, as 97% of cities in low and middle income countries do not meet the WHO air quality guidelines. It has also shown that increasing temperatures and seasonal heat are responsible for the spread of cholera and dengue.
"Heat stress is very pronounced, especially among urban elderly people and people with basic illnesses, cardiovascular diseases, diabetes or chronic kidney diseases." "At high temperatures, work in the countryside, especially in agriculture, is dangerous." North of England and California to Australia are experiencing fires with direct deaths, shifts and domestic losses, as well as breathing effects of the respiratory tract, "warns co-chairman of the coalition responsible for Hugh Montomer's study.
