Nearly half of all Americans — more than 147 million — live in counties in the U.S. where ozone or particle pollutions levels make the air unhealthy to breathe, according to the American Lung Association's "State of the Air 2014" report released today. The 15th annual national report card shows …
A new paper by Kummer & Dessler shows that recent studies suggesting a insensitive climate are flawed Arguments that the climate is relatively insensitive to the increased greenhouse effect have become the last best chance for climate contrarians, but a new study from Texas A&M; University hammers a big nail …
Chlorofluorocarbons (CFCs) are the primary cause of ozone depletion, and they also contribute to global climate change. With the global phaseout of CFCs and the coming phaseout of hydrochlorofluorocarbons (HCFCs), the substitute hydrofluorocarbons (HFCs) are increasingly used. While CFCs were originally used mainly in applications such as spray cans and …
Thousands of volatile organic compounds (VOCs) in the Earth's atmosphere exist which play an important role in various photochemical processes. However, the global model simulations of tropospheric chemistry deal with limited data of speciated VOCs. In the present study, we have used the Global Fire Emissions Database inventory of VOCs …
