Net warming from NO x emissions is a sum over warming (short-term ozone increase) and cooling (decreases in methane and stratospheric water vapor, and a long-term decrease in ozone) terms. Negative RF (cooling) contributions arise from sulfate aerosol production. Net warming from contrail cirrus is a sum over the day/night cycle.

have developed a simulator able to predict tropospheric ozone concentrations across the whole of South and East Asia. The project was carried out in collaboration with Tsinghua University in China, The Energy and Resources Institute (TERI) in India, and the International Institute for Applied Systems Analysis (IIASA) in Austria.

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.

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.

Researchers in France have found that ozone depletion above Antarctica has significantly reduced the Southern Ocean’s ability to absorb atmospheric CO 2 and has also accelerated acidification of southern polar waters, despite lesser CO 2 uptake. The results revealed that, between 1987 and 2004, around 2.3 Lenton, A., Tagliabue, and J.

CO2 ratio for this flight track segment decreased from 24.5 VOCs, primarily emitted from the tailpipes of vehicles, are a key ingredient in the formation of ground-level ozone which, at high levels, can harm people’s lungs and damage crops and other plants. ppbv/ppmv to 10.7 Source: Warneke et al.

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.
