    66  <TEXT> In addition to these adverse outcomes, PM,,2.5,, can influence the environment in ways that will eventually affect human health. Fine particles cause haze, which reduces visibility. The long-term effects of PM,,2.5,,, which settles in the soil, natural water sources, forests, and agricultural areas, are still being determined.  </TEXT>

    8   <TEXT> The impact of climate change on particulate matter is not certain, but research is underway to address these uncertainties. . If precipitation events are seen to increase with climate change, it is reasonable to conclude that PM,,2.5,, levels may decrease due to precipitation "clearing" the air. PM,,2.5,, concentrations may also be affected by air stagnation events (i.e., inversions). If air stagnation events increase in frequency with climate change, PM,,2.5,, levels are likely to rise because these events trap the pollution at the Earth's surface^2^. More research is needed to accurately quantify to what extent PM,,2.5,, levels will be affected by a changing climate. </TEXT>
