Study finds some improved cookstoves may emit more black carbon pollution than traditional mud cookstoves

Green Car Congress

In this plot, a red star under the boxes means that the mean values for hardwood and mixed fuel tests are statistically different for that stove technology class (at the 95% confidence level, p. In this regard, this study highlights the need for repeated tests to confirm statistical significance of mitigation potential.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The difference helps explain how much industrial pollution influences clouds. NASA Earth Observatory.

MIT researchers build model simulating atmospheric transport of PAHs; how chemicals get to the Arctic

Green Car Congress

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.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

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.

Study Finds Damage, Pollution from Western Wildfires Could Surge With Moderate Global Warming

Green Car Congress

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.
