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. Schematic overview of the processes by which aviation emissions and increased cirrus cloudiness affect the climate system. Aviation accounts for 3.5% —Lee et al.

Current emissions of anthropogenic greenhouse gases (GHGs) have already committed the planet to an increase in average surface temperature by the end of the century that may be above the critical threshold for tipping elements of the climate system into abrupt change with potentially irreversible and unmanageable consequences, the authors write.

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Hydrogen is not a greenhouse gas, but its chemical reactions in the atmosphere affect greenhouse gases such as methane, ozone, and stratospheric water vapor. Sand et al.

Aviation climate change impacts pathway. An an example, they point out that an SPK fuel option with zero life cycle GHG emissions would offer a 100% reduction in GHG emissions but only a 48% reduction in actual climate impact using a 100-year time window and the nominal climate modeling assumptions in the paper.

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. by 2050.

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.,
