Lead author Jonathan Patz of the Johns Hopkins School of Public Health. Other studies have shown that summer heat waves in urban areas are associated with increased mortality. Air conditioning and increased fluid intake are common ways to reduce the risk of illness from heat. The scientists also suggest implementing emergency programs in communities. The death rate due to weather is usually higher in winter than in summer, when influenza and other respiratory infections are most common.
Studies also show a correlation between snowfall and fatal heart attacks.
Patz and colleagues aren't sure how warmer winter months will influence the death rate. Climate change is expected to alter the frequency, timing, intensity and duration of extreme weather events such as tornadoes, hurricanes and extremely heavy rainfall, the researchers note. Direct results of these events are injury or death. Other effects include post-traumatic stress disorder and contamination of drinking water from flooding. Such predictions could help communities develop programs to handle weather emergencies.
