Study Links Adverse Human Health Effects to Increasing CO2 Emissions(January 3, 2008) ?
According to a study by a Stanford University researcher, increasing emissions of carbon dioxide (CO2), the most common anthropogenic greenhouse gas, cause temperature increases that in turn cause more air pollution, leading to adverse human health effects, including death.
The new study details how, for each increase of 1 degree Celsius caused by CO2, the resulting air pollution would lead annually to about a thousand additional deaths and many more cases of respiratory illness and asthma in the U.S. The study author, Mark Jacobson, used a computer model to determine the amounts of ozone and airborne particles that result from temperature increases caused by growth in CO2 emissions. He found links between air pollution and temperature increases caused by growth in CO2 emissions: higher temperatures due to CO2 increased the chemical rate of ozone production in urban areas; increased water vapor due to CO2-induced higher temperatures boosted chemical ozone production even more in urban areas; and where there was an increase in water vapor, particles that were present became more deadly, as they swelled from absorption of water. Jacobson then used a computer 4 model to project the impact on human health of more ozone and particle pollution.
