Researchers say world faces air pollution pandemic

Green Car Congress

The global total is 233 (221–250) million per year. Using a new method of modelling the effects of various sources of air pollution on death rates, the researchers estimated that globally air pollution caused an extra 8.8 In comparison, tobacco smoking shortens life expectancy by an average of 2.2 Lelieveld et al.

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

Green Car Congress

The result implies that globally, cloud changes caused by particles from all forms of industrial pollution block 1 Watt of solar energy per square meter of Earth’s surface, masking almost a third of the present-day warming from greenhouse gases. For comparison, today the Earth is estimated to have warmed by approximately 1 ?C,

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

Green Car Congress

By including upstream emissions from fuels, GHG emissions from cities exceed those attributed to direct end-use by up to 24% (for Toronto). By including upstream emissions from fuels, the researchers found that GHG emissions attributable to cities exceed those from direct end use by up to 24%. Tonnes CO 2 e/capita.
