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. CO 2 and NO x aviation emissions and cloud effects remain a continued focus of anthropogenic climate change research and policy discussions. —Lee et al.

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.

Among the findings of the report, “HFC-134a phase-out in the Chinese light-duty motor vehicle sector”, was that, considering the social cost of CO 2 e, up to 1 trillion RMB in costs (US$150 billion) required to address climate change could be avoided through 2050 by transitioning to low-GWP alternative MACs.

R134a replaced CFC-12 as the MAC refrigerant in the early 1990s due to the negative impact of CFCs on the Earth’s ozone layer. The performance-based standards for low GWP refrigerants in Europe and the United States allow automakers to choose a replacement for HFC-134a. transition to a new refrigerant is not easy.
