World Bank report examines likely impacts and risks associated with a 4 °C global warming within this century

Green Car Congress

A new report commissioned by the World Bank, and prepared by the Potsdam Institute for Climate Impact Research (PIK) and Climate Analytics, provides a snapshot of recent scientific literature and new analyses of likely impacts and risks that would be associated with a 4 °C global warming within this century.

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,

Global and regional-mean temperature responses to identical aerosol emissions in different regions. Diagonal lines (b) indicate the ratio of regional- to global-mean cooling. For example, their models show that aerosol emissions from Western Europe have 14 times the global cooling effect that aerosol emissions from India do.
