Jala News – A new study funded by NASA and NOAA has revealed that fire-prone areas and downwind regions in the western United States have witnessed a surge in premature deaths due to worsening air quality caused by wildfires. The study, which analyzed data from 2000 to 2020, raises concerns about the impact of wildfires on human health and the effectiveness of federal efforts to curb air pollution.
According to the study, the increase in frequency and severity of wildfires has led to a significant deterioration in air quality, resulting in approximately 670 premature deaths per year in the western U.S. Although efforts to reduce automobile emissions have made progress in the past 20 years, the rise in wildfires has impeded these advancements, essentially erasing previous achievements.
The researchers focused on analyzing the concentration of black carbon, a fine-particle air pollutant known to cause respiratory and heart diseases. They found that black carbon concentrations experienced an alarming annual increase of 55% in the western U.S., largely attributed to wildfires. The highest rates of premature mortality were observed in the western states and regions affected by smoke originating from Canadian wildfires. However, experts believe that the reported increase in premature deaths may be a conservative estimate.
While the Midwest has also been affected by smoke from wildfires, the direct impact on health seems minimal for now. However, experts caution that if wildfires continue to increase in intensity or frequency, the air quality in the region could deteriorate significantly.
In contrast, the eastern U.S. did not experience major declines in air quality during the studied time period, indicating a disparity in the effects of wildfires across the country.
To arrive at their findings, the researchers utilized satellite data and ground-based stations, employing “deep learning” techniques to calculate black carbon concentrations with a one-kilometer resolution. These findings underscore the growing intensity and frequency of wildfires in the United States, which undermine efforts to reduce anthropogenic emissions and aggravate air pollution, posing substantial risks to human health.
The study’s implications shed light on the urgency of addressing the root causes of wildfires and implementing comprehensive strategies to mitigate their adverse effects on air quality. The findings highlight the need for continued research and cooperation among federal agencies, regional authorities, and the public to safeguard public health and the environment from the perilous consequences of wildfires.
