Persistent organic pollutants are chemicals of substantial international concern. GEOS-Chem captures observed seasonal trends with no statistically significant difference between simulated and measured mean annual concentrations. The presence of these pollutants in the Arctic is important for several reasons.
A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al. of the data.
This potential leap in destructiveness and pollution—mainly from an increase in wildfire frequency—is forecast by computer models calculating impacts of moderate global warming on western US wildfire patterns and atmospheric chemistry. The increase is due mainly to the simulated rise in wildfire frequency in the future, warmer climate.
Although large emissions cuts are urgently needed to achieve global climate goals, it may take decades before we can measure the effect of the reductions on global temperature evolution, according to a new study by researchers at Norway’s CICERO Center for International Climate Research. —Bjørn Samset. —Jan Fuglestvedt.
Researchers at the University of California, Irvine and other institutions have conducted a statistical analysis of pollution exposure and yields from 1980 to 2015 on a key sector making up about 38% of the state’s total agricultural output: perennial crops such as almonds, grapes, nectarines, peaches, strawberries and walnuts.
The state’s latest Greenhouse Gas Emissions Inventory shows that California emitted 429 million metric tons of climatepollutants in 2016—a drop of 12 million metric tons, or three percent, from 2015. This ambitious target will require California to more than double the rate at which it has been cutting climate-changing gases.
Using a variety of data including direct observations, computer-generated models, and estimates from countries’ energy statistics, the team created a global CO 2 budget—the amount of CO 2 produced and consumed—from 1959 to 2008. Tags: Climate Change Emissions. between 2000 and 2008, compared with 1% per year in the 1990s.
The report for the Department for Transport is based on a survey module included in the Office for National Statistics’ Opinions (Omnibus) survey which has been carried out each August since 2006. It found that 65% of respondents spontaneously selected emissions from road transport as a cause of climate change. Source: DfT.
The findings, published in the 21 September issue of Atmospheric Chemistry and Physics , are generally consistent with official Chinese government statistics and could bolster their credibility as international negotiations proceed on commitments of China and other nations to combat climate change. Munger, J. McElroy, M. Nielsen, C.
A new report by the UK’s Office for National Statistics (ONS) finds that greenhouse gas (GHG) emissions from road transport in the UK rose by 6% from 1990 to 2017.

Information on the other two greenhouse gases, methane (CH 4 ) and nitrous oxide (N 2 O), is only available until 2012, as international statistics on agricultural activities—the main source of these emissions—are not updated as frequently as on energy and industry-related activities. Other greenhouse gases keep creeping up.
A Georgia Tech City and Regional Planning study on climate change concludes that “smart growth” combined with the use of hybrid vehicle technology could reduce cities’ carbon dioxide (CO 2 ) emissions significantly by 2050. Percent change in median CO2 by scenario relative to 2000. Stone et al. 2009) Click to enlarge. Stone et al.
In an effort to reliably predict efficiency and pollutant emissions for new engines and fuels, computer simulations are used to study fundamental turbulence-chemistry interactions. Low emission, low temperature engine concepts of the future operate in regimes where combustion is poorly understood.
First, some background from the New York Times : The rule increasingly limits the amount of pollution allowed from tailpipes over time so that, by 2032, more than half the new cars sold in the United States would most likely be zero-emissions vehicles in order for carmakers to meet the standards. It very much is not. Fear is effective.
China, the world’s largest pollution emitter, is going green with clean energy alternatives and doing so quickly. Recent energy reports detail the nation’s commitment to implementing solar and wind power, so much so that it is expected to achieve its 2030 clean energy targets by the end of the month. Take notes, everyone.
A new study led by researchers from Northwestern University projects that if electric vehicles replaced 25% of combustion engine cars currently on the road, the United States would save approximately $17 billion annually by avoiding damages from climate change and air pollution. Peters, D. Schnell, J. Kinney, P. Naik, V., & Horton, D.
An international team of scientists, led by NTU Singapore, has linked increased air pollution to an uptick in cases of lung adenocarcinoma (LADC) worldwide. Black carbon is a pollutant that is classified as under PM 2.5. Our findings pinpoint the necessity and urgency to reduce air pollutant emissions especially black carbon.
