of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. The study was published in the journal Atmospheric Environment. Aviation accounts for 3.5% Negative RF (cooling) contributions arise from sulfate aerosol production.

have developed a simulator able to predict tropospheric ozone concentrations across the whole of South and East Asia. Tropospheric ozone is the main cause of photochemical smog, an atmospheric pollutant harmful to human health and plant growth. Toyota Motor Corporation (TMC) and Toyota Central R&D Labs.,

Study Finds Ozone, Nitrogen Change the Way Rising CO2 Affects Earths Water

Green Car Congress

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways.

Urban CO2 Domes May Enhance May Increase Ozone and PM, With Accompanying Increase in Mortality

Green Car Congress

In a new study published online 10 March in the ACS journal Environmental Science and Technology , however, Stanford University professor Mark Jacobson finds that local CO 2 emissions in isolation may increase local ozone and particulate matter. Although the health impacts of such changes are uncertain, he notes, they are of concern.

More Reflective Roofs and Pavements Could Help Offset Climate Emissions

Green Car Congress

Both studies indicate a qualitatively similar response of a reduction in radiative forcing or an increase in total outgoing radiation for an increase in urban albedo and the values indicate an approximate range in potential emitted CO2 offset that may be expected if urban albedos were increased. —Menon et al.
