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

Green Car Congress

In climate models, if you simulate the world with sulfur emissions from shipping, and you simulate the world without these emissions, there is a sizable cooling effect from changes in the model clouds due to shipping. This path is also part of a popular open-ocean shipping route between Europe and Asia. C, or 1.8 ?F,

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

Green Car Congress

The first real-world, head-to-head comparison of improved cookstoves (ICs) and traditional mud stoves has found that some ICs may at times emit more of the black carbon particles that are linked to serious health and environmental concerns than traditional mud stoves or open-cook fires.

WHO data: global annual PM10 increased by 6% during recent 3-year period; based on data from 851 cities

Green Car Congress

population weighted comparisons in annual mean PM 10 for a three?year WHO notes that the results for the 851 cities are to be interpreted with caution, as yearly variations due, for example, to climatic changes can be important and 3?year year comparisons do not necessarily represent trends, in particular when changes are limited.
