It makes an important contribution to the scientific understanding we have of the role of aviation for climate change—an understanding decision-makers and politicians may need on the way to achieving the goals of the Paris Agreement. This new study is based on a thorough review of a decade of research on aviation emissions.

Noting the references in scientific and policy literature to the need for fast-action mitigation to help avoid DAI and abrupt climate changes, the authors define “fast-action” to include regulatory measures that can begin within 2–3 years, be substantially implemented in 5–10 years, and produce a climate response within decades.

Hydrogen is not a greenhouse gas, but its chemical reactions in the atmosphere affect greenhouse gases such as methane, ozone, and stratospheric water vapor. The main changes in the radiative forcing due to 1 Tg flux of hydrogen; methane (green bars), ozone (yellow), stratospheric water vapor (purple), and aerosols (red).

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.

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.

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.,

Aviation climate change impacts pathway. In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming. The corresponding reduction in CH 4 , which is an important ozone precursor, leads to a long-term reduction in ozone. Credit: ACS, Stratton et al.
