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

Green Car Congress

The open-access study was published in AGU Advances, a journal of the American Geophysical Union. 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. C, or 1.8 ?F,

Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

The study shows that Americans face the risk of a 70% increase in unhealthy summertime ozone levels by 2050, assuming continued greenhouse gas emissions with resultant significant warming (IPCC Scenario A2 and RCP (Representative Concentration Pathway) 8.5.). The new study was among the first conducted on the new 1.5-petaflop

UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

The contribution of HFCs to climate forcing is currently less than 1% of all greenhouse gases. If HFC emissions continue to increase, they are likely to have a noticeable influence on the climate system. Climate and the Ozone Layer. There is inherent uncertainty in such projections, the report authors caution.).

Potent GHG SF6 rapidly accumulating in atmosphere, driven by demand for SF6-insulated switchgear in developing countries

Green Car Congress

In an open-access study in the EGU journal Atmospheric Chemistry and Physics , an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6 ) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries.
