‘Weather penalty’ pollution led to 20,000 US deaths in last 20 years

Published in ERW, 14 Sep 2015

Excess pollution arising from weather changes over the past two decades has led to more than 20,000 deaths in the US, according to researchers. Their result, from a study exploring the effect of weather conditions on ozone and fine particulate matter, suggests that pollution-related deaths will continue to rise in the future.

Every year in the US, there are thousands of deaths thought to result from ozone and more than 100,000 deaths linked to fine particulate matter. The presence of these pollutants in the atmosphere is affected by factors like temperature, wind speeds, water vapour pressure and precipitation. Scientists predict that, with temperatures rising and air currents becoming more stagnant in the US, the amount of ozone and particulate matter will rise. […]
