This is the effect that a team of researchers from the University of Wisconsin-Madison (USA) predicted an additional 1,000 deaths a year in the eastern part of the country by mid-century because of the high levels of air contamination caused by the increased use of fossil fuels to cool buildings.
The analysis combines the projections of five different models to forecast more energy during the summer in a warmer world and how that would affect the energy consumption of fossil fuels. , the quality of air and, therefore, human health in a few decades.
The principal author of the study, Jonathan Patz, of UW-Madison, assured that during the summer seasons of the future, in which the waves of heat will increase in terms of frequency and intensity, air conditioning will "save lives".
However, Professor Patz warned that if this upward use of air conditioning is dependent on energy Due to fossil fuels, air pollution "will cause more illness and death".
Residential and office buildings are the largest energy consumers in the United States, responsible for more than 60% of energy demand in the East. The report predicts an additional 13,000 annual human deaths caused by higher levels of fine particulate matter in the summer and 3,000 by ozone in the United States by mid-century.
Most of these deaths will be attributable to natural processes such as atmospheric chemistry and natural emissions, which are affected by rising temperatures.
However, about a thousand of these deaths will occur each year due to the increased use of According to analysis, air conditioning is powered by fossil fuels.
The results of the new study, according to the Wisconsi N team, point to the need to move to more sustainable energy sources, such as wind and solar energy, and to deploy more energy efficient air conditioning equipment.
