I read something rather different: > CO2 is the main greenhouse gas emitted by ships. Methane (CH4) and nitrous oxide (N2O) emissions from ship engines have a minor global warming role compared with CO2. Further, SOx, NOx, PM and VOC also have a minor role in global warming. Particulate matter arising from SOx emissions has a potential cooling effect and/or creates local climate disturbance (see section 6.1). The sulphur content of marine fuels will decrease due to IMO MARPOL Annex VI and other measures. Page 27 says: > Fuglestvedt et al[10] claim net cooling for shipping. Bows pointed out that their methodology was flawed as they did not account for cumulative effect of CO2[11]. That is, CO2 that has accumulated goes on accumulating, but other pollutant concentrations remain steady. The sulphate particulates have a relatively short lifetime in the atmosphere in terms of global warming.
