Most of this infrared radiation passes through the atmosphere, but some is absorbed by GHG molecules like CO 2 , methane, ozone and others. Based on recent emissions inventories (2000 for global and 2005 for the United States), the majority of global BC emissions come from Asia, Latin America, and Africa. Source: EPA.
