Earth Calendar for July 2nd and July 3rd

Jul 2, 2012

On hot, summer days, surface temperatures of roofs and pavement can be from 50 to 90 degrees warmer than the air temperature! These hot surfaces contribute to “urban heat islands” where temps in cities are hotter than surrounding, less developed areas. The urban heat island effect can be particularly pronounced at night, when city temperatures may be as much as 22 degrees higher than surrounding areas. These higher temperatures in cities have a number of impacts, including increased energy use for air conditioning, increased emissions of air pollutants, and impacts on human health.   Older individuals are especially vulnerable to heat-related illnesses. The body’s cooling mechanism doesn’t work as efficiently as we age and living alone or being confined to a bed can further increase vulnerability.   Just a few hours per day in an air-conditioned building can reduce risk of illness. If your home does not have A/C, visit a movie theater, library, mall or designated community cooling center. A fan may provide some relief, but when temperatures reach the high 90′s, electric fans do not prevent heat-related illness.  Wear light-weight, loose clothing that is light in color.  Drink plenty of fluids and avoid drinks with caffeine, alcohol or lots of sugar, which can cause dehydration.   If you have a family member, friend or neighbor who is at risk, visit them regularly.  If you see signs of heat-related illness, seek help immediately.  Learn more at the website.    


On Our Calendar.  Grab your wading boots and head to Clermont County’s Sycamore Park. We’ll splash around in the stream searching for crayfish, snails, beetles and other aquatic critters. Then use what you caught to determine how healthy the river is. Bring a net if you have one and meet at the river access July 11th, 6:30 pm.  Call 513 732-2977 or visit the Clermont County Park website.
