Climate change and health: How vulnerable is your city?

As temperatures rise, so could the threats to your health.

Climate experts predict average temperatures in California could rise between 4.7 to 10.5 degrees Fahrenheit by the end of this century, potentially worsening illnesses related to extreme heat and air pollution, according to Natural Resources Defense Council, which released web-based climate change impact maps Wednesday.

The maps forecast the average number of days likely to spread infectious diseases, such as dengue fever, and when people might suffer from extreme heat, unhealthful air pollution, as well as flooding and droughts. Residents may also use the site to find out more about their city’s strategy to prepare for the effects of climate change and tips to mitigate the effects of unhealthy days.

“Climate change is one of the most serious public health threats in the 21st century,” said Kim Knowlton, NRDC senior scientist. Knowlton said warmer weather can exacerbate smog and ragweed pollen, threatening those suffering from allergies, respiratory problems and asthma.

“We need to start connecting the dots between climate change and our health,” Knowlton said. “It’s time we make it a personal, national priority.”
