Climate effects of non-compliant Volkswagen diesel cars
On-road operations of Volkswagen light-duty diesel vehicles equipped with defeat devices cause emissions of NOx up to 40 times above emission standards. Higher on-road NOx emissions are a widespread problem not limited to Volkswagen vehicles, but the Volkswagen violations brought this issue under the spotlight. While several studies investigated the health impacts of high NOx emissions, the climatic impacts have not been quantified. Here we show …
Perspective has a strong effect on the calculation of historical contributions to global warming
The politically contentious issue of calculating countries’ contributions to climate change is strongly dependent on methodological choices. Different principles can be applied for distributing efforts for reducing human-induced global warming. According to the ‘Brazilian Proposal’, industrialized countries would reduce emissions proportional to their historical contributions to warming. This proposal was based on the assumption that the politica…
Bounding the role of black carbon in the climate system
Black carbon aerosol plays a unique and important role in Earth's climate system. Black carbon is a type of carbonaceous material with a unique combination of physical properties. This assessment provides an evaluation of black‐carbon climate forcing that is comprehensive in its inclusion of all known and relevant processes and that is quantitative in providing best estimates and uncertainties of the main forcing terms: direct solar absorption; i…
A unifying framework for metrics for aggregating the climate effect of different emissions
Multi-gas approaches to climate change policies require a metric establishing equivalences among emissions of various species. Climate scientists and economists have proposed four kinds of such metrics and debated their relative merits. We present a unifying framework that clarifies the relationships among them. We show, as have previous authors, that the global warming potential (GWP), used in international law to compare emissions of greenhouse…
The integrated global temperature change potential (iGTP) and relationships between emission metrics
The Kyoto Protocol compares greenhouse gas emissions (GHGs) using the global warming potential (GWP) with a 100 yr time-horizon. The GWP was developed, however, to illustrate the difficulties in comparing GHGs. In response, there have been many critiques of the GWP and several alternative emission metrics have been proposed. To date, there has been little focus on understanding the linkages between, and interpretations of, different emission metr…
Climate and air quality-driven scenarios of ozone and aerosol precursor abatement
Tropospheric ozone and aerosols in climate agreements
Surface Ozone in China and its Possible Impact on Agricultural Crop Yields
Emissions of ozone precursors are expected to multiply the next 20 years in China, and the levels of photo-oxidants may increase substantially. Increased surface ozone gives cause for concern regarding the prospects for Chinese agricultural production. We show that crop production may be substantially reduced in the future due to elevated ozone concentrations, and that productivity may already be affected for some crops. However, crop-yield loss …
