Particulate Matter in a Changing World: Grants to Combat the Impacts of Climate Change
By Christina Burchette
There are certain things that are always changing: the weather, fashion trends, and technology (which iPhone are we on again?) are a few that come to mind. I can always count on the fact that these things won’t stay the same for long. But there are other things that I typically expect to remain the same: I expect to get hungry around lunchtime, I expect the bus to come every morning, and I expect to be able to breathe clean air. I don’t even think about the possibility of these things not happening—until something changes.
I definitely don’t think about air quality often or expect it to change. As long as I’m breathing and well, why would I? But in reality, air quality changes every day, and over time it may change a lot depending on how we treat our environment—and we need to be ready for these changes. This is why EPA recently awarded research grants to 12 universities to protect air quality from current and future challenges associated with climate change impacts.
Climate change is affecting air quality by influencing the type and amount of pollutants in the air. One type of pollutant present in our air is particulate matter, or PM. Long-term exposure to PM is linked to various health effects, including heart disease and lung function, and it doesn’t take a high concentration to affect our bodies. The more PM there is in the air, the more likely we are to be affected by health conditions.
With EPA Science to Achieve Results (STAR) grants, university researchers are approaching the future of air quality from multiple angles with a focus on learning more about the PM-climate change relationship. They will study the impacts of increased wildfire activity that generates PM, often called soot, in the Rocky Mountains. They will look at the impacts that climate change and land use change have on the development of dust storms in the West and Southwest; and they will evaluate the best means of energy production in California where air quality is among the worst in the nation to reduce health care costs and lower levels of PM and greenhouse gases.
Over the next few decades, climate change will be the catalyst for various environmental trends, so finding a way to manage the impacts of these trends is essential to protecting our health. The work these grantees do will help to inform air quality managers and others to make sustainable and cost-effective decisions that keep our air quality at healthy levels and protect public health and the environment. That way, future generations will think of good air quality as something we can expect.
