• A study estimates 15,000 deaths and $160 billion in economic costs in the US from 2006 to 2020 are attributable to climate change-related wildfire smoke exposure.
• The study focused on PM2.5, a dangerous particulate matter in wildfire smoke, and its impact on mortality, particularly for vulnerable populations.
• Experts suggest addressing both climate change and land management practices like prescribed burns to mitigate the health impacts of wildfire smoke.

A new study published in Nature Communications Earth & Environment reveals a significant link between climate change-fueled wildfires and increased mortality and economic costs in the United States. The research, analyzing data from 2006 to 2020, estimates that approximately 15,000 deaths and $160 billion in economic damages can be attributed to exposure to fine particulate matter (PM2.5) from wildfire smoke exacerbated by climate change. The study highlights the growing threat of wildfires due to increasing drought and extreme weather conditions, emphasizing the urgent need for mitigation strategies.

• What: A study links climate change to increased deaths and economic costs from wildfire smoke exposure in the US, focusing on the impact of fine particulate matter (PM2.5).
• Who: The study was conducted by Nicholas Nassikas and a multidisciplinary team of researchers. Experts like Lisa Thompson, Jacob Bendix, Marshall Burke, and Patrick Brown provided commentary on the study's findings.
• When: The study analyzed data from 2006 to 2020. The study was published on Friday in the journal Nature Communications Earth & Environment.
• Where: The study focused on the United States, with specific attention to states like Oregon and California, which experienced higher mortality rates.

The study provides compelling evidence of the link between climate change, increased wildfire activity, and adverse health outcomes. The focus on PM2.5 is critical, as it is a known health hazard, particularly for vulnerable populations. While the study highlights the impact of climate change, it is important to consider other factors that contribute to wildfires, such as land management practices. Experts like Patrick Brown raise valid concerns about overemphasizing carbon emission mitigation as the sole solution. A comprehensive approach that includes both climate action and effective land management strategies is essential to address the growing threat of wildfire smoke.

We’re seeing a lot more of these wildfire smoke events. What does it really mean in a changing environment for things like mortality, which is kind of the worst possible health outcome?

This study drives home how far-reaching the impacts are.

Yet in many regions, the more immediate life‑saving action may be fuel breaks, prescribed burns, ignition‑source regulation, public health efforts, etc.

If we have days in what’s called the orange zone or red zone, or even higher zones, it might be a good idea to stay inside and take more preventative measures to protect your health

The study's findings underscore the urgent need to address climate change and its impact on wildfire activity and public health. While the research provides valuable insights into the health consequences of wildfire smoke exposure, further research is needed to fully understand the complex interplay of factors contributing to wildfires. A multi-faceted approach that combines climate action, effective land management practices, and public health initiatives is crucial to mitigate the growing threat of wildfires and protect communities from their harmful effects.
