I'd like , please http://www.onsiteworkshops.com/medical-school-personal-statement-editing-services/ help assignment  Emissions of carbon dioxide have been responsible for over half of the warming influences to date. Methane, carbon monoxide, halo-carbons and nitrous oxide also have a significant warming influence. ﾂ�The major cooling influences are NOx gases, aerosols (like sulphates and organic carbon) and changes in land albedo (how shiny it is). ﾂ�The effect aerosols have on clouds also has a large cooling effect, though there is significant uncertainty in quantifying this.
