Forestry fire fires reflect the progress of the clean air
Forest fires reflect contracts from the clean air standards in Canada and the United States, according to the new data published on Thursday.
Researchers issued at the annual University of Chicago Life Index Air Quality (AQLI), which tracks air pollution and how it affects the average life expectancy. This year’s report analyzed the data collected in 2023.
That year, where Canada faced the worst fire season in history, it burns 40 million Land acres caused, and fires have caused air pollution concentrations to levels that have not been seen since 2011 in the United States and since 1998 in Canada, AQLI began to record air quality data. Both Canada and the United States have made great steps in reducing air pollution in the past – but forest fires are the opposite of this progress. The two countries witnessed the highest increases in air pollution around the world in 2023 – although there are strict air quality rules at the time. High pollution levels are concentrated in the pockets of the United States, and the geographical distribution of pollution in the United States has changed, and the most polluted provinces in the United States in California usually concentrated, but that year, forest fires in provinces in many other states including Wisconsin, Illinois, and Indiana, to the far south like Mississippi, caused them to include them among the most states.
Throughout the world, 2023 concentrations of PM2.5 – small particles 2.5 micrometers or less in their diameter that are launched in the air by fires and other pollution sources – witnessed 1.5 % compared to 2022 levels, and AQLI data – which indicates about five times the WHO’s guidelines (World Health Organization). The broad -term exposure to PM2.5 can increase the risk of healthy effects including heart disease, lung cancer and stroke.
The results are a blatant warning of what could be a new fact to treat air quality. The extinguishing season this year was the second worst worst, with a total 18.5 million acres Burning it since the beginning of 2025. Climate change causes an increase in the frequency and firefights of forests, with the largest increases in the western United States and the northern forests in North America and Russia, according to L Nassa He studies.
This comes at the same time as the Trump administration is working to decrease clean air standards in the United States. In March, the Environmental Protection Agency announced that it is planning to retract landmark pollution standards, including National surrounding air quality standardsWhich regulates harmful pollutants such as gem.
Also management Proposal The cancellation of “discovery of exposure” for the year 2009, which decided that greenhouse gases were a threat to public health and provided the legal spine of regulations under the clean air law. The researchers say that climate change and air pollution are deeply linked and that lowering carbon dioxide emissions, which raises temperatures and Worse forest firesIt is an essential part of reducing air pollution.
The researchers wrote in the report: “All of the climate change and air pollution are driven by the same source – the combustion of the faction fuel from vehicles, power and industry stations,” the researchers wrote in the report. “In this regard, the cuts in fossil fuel consumption have the ability to reduce air pollution concentrations and the risk of sabotage climate change.”
