The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate.
When airborne particles (green) form before PAHs adhere, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the longer-lasting particles enable the long-range transport of the pollutants (bottom).
The study, set in Singapore, suggests that better air quality will bring about climate co-benefits in reducing electricity generation via lower household demand, and thus mitigating carbon emissions. This is important for policymakers when forecasting and influencing future emissions paths in the context of climate change.
Schematic diagram of the trade-offs between the implications for regional air quality and global climate change of new policies for management of the atmosphere. The project builds upon the idea that air quality and climate change issues are linked through “one atmosphere”, an approach that demands coordination and multi-tiered approaches.
Shown are the tipping elements [large-scale components of the Earth’s system] and the temperature threshold range that initiates the tipping. This would mean that the climate system is close to entering if not already within the zone of “dangerous anthropogenic interference” (DAI). From Molina et al. Earlier post.)
A new study by researchers from Canada, Norway and China indicates that warming in the Arctic is revolatilizing persistent organic pollutants (POPs) that have accumulated in sinks such as water and ice. Their paper appears in the journal Nature Climate Change. Nature Climate Change doi: 10.1038/nclimate1167. —Ma et al.
The FY 2011-2012 plan focused primarily on five areas of interest: sustainable communities; behavior and technology adoption; health and air pollution exposures; air pollution science; and greenhouse gas targets. These regulations have led to considerable improvements in air quality throughout California.
EU-funded researchers have developed an innovative climate control system (CCS) that extends the range of electric vehicles while enhancing passenger comfort. At present a substantial amount of energy is required to run the CCS within electric vehicles, creating a major drain on the battery and limiting the range of the car.
Aggregated damage costs by pollutant. Air pollution from the 10,000 largest polluting facilities in Europe cost citizens between €102–169 billion (US$135–224 billion) in 2009, according to a new report from the European Environment Agency (EEA) which analyzed the costs of harm to health and the environment caused by air pollution.
Through 2042, EPA estimates the net climate and health benefits of the standards on new gas and existing coal-fired power plants are up to $85 billion. EPA’s analysis found that power companies can implement the standards with a negligible impact on electricity prices—well within the range of historical fluctuations.
the distribution of black carbon in the atmosphere and determine its role in the climate system. Black carbon (BC) is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this pollutant’sclimate impact.
A recent study by an international team calculated that shipping causes a net cooling of climate across all parametrizations of the indirect aerosol effect (IAE) and scenarios throughout the period 1900?2050. Shipping-induced global temperature change in 2050 using different parameterizations of Indirect Aerosol Effect (IAE).
The California Air Resources Board released a new draft of California’s Short-Lived ClimatePollutant Strategy to significantly reduce the near-term climate impacts of these potent pollutants. Methane is the most abundant of the short-lived climatepollutants in California.
However, while greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate because the aerosol particles cause more of the sun’s light to be reflected away from the planet. In many cases, the strongest climate effects of aerosols are felt far from where the aerosols are emitted.
A climate-neutral alternative to petroleum-based fuels, they also offer the potential for significantly reduced overall emissions, allowing Tenneco’s Clean Air experts to better manage any remaining pollutants through the aftertreatment process. We are excited to be an active part in the development of this type of technology.
A new study by led by Nadine Unger at NASA’s Goddard Institute for Space Studies (GISS) that analyzes the net climate impacts of emissions from economic sectors rather than by individual chemical species has found that on-road transportatation is and will be the greatest net contributor to atmospheric warming now and in the near term.
Policies incentivizing the private sector to push to develop innovative “clean” technologies are likely to play a key role in achieving climate stabilization. Respectively, Title IV of the 1990 Clean Air Act and the Ozone Transport Commission/NO x Budget Program.). c personnel and organizational innovative capacity. —Taylor 2012.
Cutting the amount of short-lived, climate-warming emissions such as soot and methane won’t limit global warming as much as previous studies have suggested, according to a new study from the Joint Global Change Research Institute in College Park, Md., More realistic emission reductions would likely provide an even smaller climate benefit.
The new metamodel is capable of efficiently simulating the urban concentration, surface deposition, and net export flux of these species that are important to human health and the global climate. Urban regions account for an ever increasing fraction of Earth’s population, and are consequently an ever increasing source of air pollutants.
Range Energy announced that its 53-foot electric trailer, the RA, is now eligible for point-of-sale incentives up to $80,000/unit through the California Air Resources Board Clean Off-Road Equipment (CORE) Voucher Program. Range’s platform also works as a mobile power unit.
The climate change benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. °C (within a likely range of 0.2-0.7 Click to enlarge.
Although viewed as a potential target in the global effort to reduce climate change, atmospheric black carbon particles absorb significantly less sunlight than scientists have predicted, according to a new study by an international team of researchers, published in the journal Science. —Cappa et al.

Preparing the US for the impacts of climate change. Earlier post.).
They monitored indoor and outdoor ozone levels, along with other pollutants. The 24-hour ozone exposure concentrations ranged from 1.4 parts per billion (ppb), corresponding to outdoor concentrations ranging from 4.3 In contrast, only 31 million Americans live in counties where other pollutants exceed EPA standards.

A study published in Nature Climate Change suggests that thermoelectric power plants (i.e., nuclear and fossil-fueled generating units) in Europe and the United States are vulnerable to climate change due to the combined impacts of lower summer river flows and higher river water temperatures. Source: van Vliet et al.
In California, reductions in emissions of black carbon since the late 1980s—mostly from diesel engines as a result of air quality programs—have resulted in a measurable reduction of concentrations of global warming pollutants in the atmosphere, according to a study examining the impact of black carbon on California’s climate.
