Climate Changes

Hotter temperatures and lack of rainfall also increase the risk of drought and wildfires, both of which create particle pollution. Wildfires have become a major source of extremely high particle levels in places hundreds of miles from fire sites. Dust storms also contribute to particle pollution, and they are expected to increase as soil dries out and the water table drops. Rising temperatures and reduced rainfall create conditions that foster the formation of ozone. The hotter weather leads to longer periods of high ozone levels, while stagnant air, caused by changes in weather patterns, prevents the dispersal of air pollutants. 

Climate change is intensifying the frequency and severity of extreme weather events, including flooding, which poses significant health risks. Flooding can force families to evacuate. Upon returning, they often face homes damaged by mold, polluted floodwater residue, and structural damage, which can expose them to indoor air pollution. Cleaning and repairing homes after flooding can release harmful particles and contaminants, worsening respiratory conditions and increasing the risk of infections.

Climate change is significantly influencing the prevalence and intensity of allergens, making allergy sufferers' lives more challenging.Rising temperatures have been shown to extend the growing seasons of many plants, allowing them to produce more pollen. Due to warmer temperatures, allergy seasons are becoming longer. As a result, allergy sufferers experience more severe symptoms like sneezing, itchy eyes, and congestion.

Climate change is increasing the frequency of heat and drought, which heightens the risk of wildfires. Wildfire smoke contains microscopic particles that can cause respiratory issues like coughing, asthma flare-ups, and heart attacks, and can even lead to premature death, particularly for individuals with heart and lung conditions. The danger isn't limited to those living near wildfires—smoke can travel hundreds of miles, affecting people in distant areas.
