Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

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.

Researchers present new explanation for the long-range transport of PAH pollutants

Green Car Congress

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).

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

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.

California ARB and NOAA Collaborating in $20M Research on Interaction of Air Pollution and Climate Change; One Atmosphere Approach

Green Car Congress

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.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

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.)

Study indicates warming Arctic is remobilizing persistent organic pollutants into the atmosphere

Green Car Congress

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.

California ARB soliciting research suggestions for FY 2012-2013 plan; sustainable communities, behavior, pollutant exposure, air pollution science, GHG targets

Green Car Congress

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.
