Editor's Notes

  • Maps show the increase in frequency of extreme daily precipitation events (a daily amount that now occurs once in 20 years) by the later part of this century (2081-2100) compared to the later part of last century (1981-2000).
  • The key question is why does it matter that temperatures are rising? It matters because it is affecting many parts of our life. The one we are focusing on today is how it affects our health. Rising temperatures and sea levels are affecting environmental elements. These include more extreme weather events such as heat waves; floods; hurricanes; droughts; wildfires; and worsening air quality. These factors may also allow various vectors – such as mosquitoes and ticks – to live in places they previously couldn’t survive. These changes in our environment have health effects. They are expected to lead to more heat stress, flood and hurricane-related illnesses, water quality concerns, respiratory health problems, allergies, and various vector borne diseases such as Lyme disease, West Nile Virus, and Rocky Mountain spotted fever.
  • Floods impact public health in many ways. Property damage often includes mold growth that leads to respiratory health problems. Floodwaters can overwhelm the sewage treatment facilities contaminating drinking water. At farms with livestock, flood waters can bring bacteria from the animal waste to drinking water wells. As microorganisms enter the drinking water supply they can cause waterborne diseases. One study found that 51% of waterborne disease outbreaks in the US happened after an extreme rain event. Injuries are also common when people drive in floodwaters. Psychological distress as a result of being exposed to the trauma of a flood is also a health concern that must be addressed. The distress can result from being displaced, having to worry about the financial and sentimental impact of the property damage, or witnessing people in distress during the event itself. Finally, it is important to pay special attention to vulnerable populations, such as the elderly in nursing homes, during flooding events. Nursing home residents were especially impacted during and after Hurricane Katrina. They experienced a significant increase in mortality and hospitalization during Katrina.
  • This figure shows how the length of ragweed pollen season changed at 11 locations in the central United States and Canada between 1995 and 2015. Red circles represent a longer pollen season; the blue circle represents a shorter season. Larger circles indicate larger changes.
  • Populations exposed to ozone air pollution are at greater risk of dying prematurely, being admitted to the hospital for respiratory hospital admissions, being admitted to the emergency department
  • Wildfires emit
    Trends in the annual number of large fires in the western United States for a variety of ecoregions. The black lines are fitted trend lines. Statistically significant at a 10% level for all regions except the Snake Plain/Columbian Plateau, Basin and Range, and Mediterranean California regions
  • The changing geographic range of vectorborne diseases is another public health concern for Illinois. These two image shows where there were reported Lyme disease cases in 1996 and in 2012. Each blue dot represents a Lyme disease case. Over the 16 year-period you can see the geographic ranges spread north and west. In 1996, there were only a handful of cases in Illinois, but, by 2012, there is a dark blue section in northeastern Illinois and many more scattered cases in northwest, central, and east Illinois. The trend of warming temperatures is seemingly linked to vectors and the diseases they carry. As this trend continues, vectors, such as ticks and mosquitoes, will be able to live in environments that used to be too cold for them.

  • NOAA image of algal bloom, eastern Lake Erie, summer 2011
  • Toxic algae prefer warmer water
    Prevents water from mixing, allowing algae to grow thicker and faster.
    Algal blooms absorb sunlight, making water even warmer and promoting more blooms.
  • Psychological distress is of particular concern following natural disasters and is often associated with all climate sensitive illnesses. A study conducted after Hurricane Katrina looked at the impact of the hurricane on 815 people, to investigate the mental health effects post hurricane. An important finding was that natural disasters not only lead to mental health problems but can continue to cause problems even after a year post- event. The rates for all the conditions increased from 5-8 months after Katrina to a year after Katrina. Another important finding is that there was no difference between race and socioeconomic groups. Exposure to a traumatic event does not discriminate and leads to psychological distress for all.
