Climate change affects human health and wellbeing through extreme weather, wildfires, decreased air quality, and diseases transmitted by insects. Climate disruptions to agriculture are increasing and will become worse over this century, a trend that will diminish America’s food supply. Groundwater supplies are stressed, and water quality is diminishing in many areas. For coastal communities, sea level rise, combined with coastal storms, has increased the risk of erosion, storm surge damage, and flooding. Extreme heat and heavy downpours are affecting our roads, rail-lines, airports, seaports, and energy infrastructures. For decades, scientists saw climate change as a distant problem. We know that thinking is wrong, and changes are needed now!
