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. F), a change that the Intergovernmental Panel on Climate Change projects would have significant societal impacts.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

An international study of 10 global cities found that a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the greenhouse gas emissions (GHGs) attributable to cities.

Final session on international mercury convention this week expected to culminate in agreement; UNEP Global Mercury Assessment 2013 finds industrial source Hg emissions may be rising

Green Car Congress

Comparison of Hg emissions in 2005 and 2010, by selected sector and region. The session is expected to culminate in the adoption of a new convention by the 147 states attending the session to reduce mercury emissions and releases to the air, water and land. Anthropogenic releases of mercury to water total 1000 tonnes at a minimum.
