The rapidly growing space industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL and published in the journal Earth’s Future as an open-access paper. The space industry is one of the world’s fastest growing sectors.

The human health benefits associated with improvements in air quality related to the reduction in greenhouse gas emissions improvements can offset 26–1,050% of the cost of US carbon policies, depending upon the type of policy, according to a new study by a team from MIT. Carbon-reduction policies significantly improve air quality.

A study by researchers at the University of Texas found that in general, use of plug-in hybrid electric vehicles (PHEVs) can lead to an increase in ozone during nighttime hours (due to decreased scavenging from both vehicles and EGU stacks) and a decrease in ozone during daytime hours.

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.

Researchers at MIT have developed a new detailed air-quality model to simulate the effects of physical, chemical, and meteorological processing of highly reactive trace species in urban areas. Thus excluding the urban processing model could lead to an overestimation of some aerosols and an underestimation of others.

Chlorofluorocarbons (CFCs)—commonly used in refrigerators and air conditioners—play a role in creating a hole in the ozone layer over Antarctica. HFCs are particularly strong greenhouse gases, so even relatively small levels in the atmosphere can contribute to warming.
