A)aerosols such as sulfur haze typically remain in the atmosphere for about a year whereas greenhouse gases remain for hundreds of year
B)greenhouse gases help warm the planet 24 hours a day whereas sulfur haze cools the Earth only during the day when the sun is shining
C)there has been a concerted effort to increase sulfur emissions to counter the effects of the enhanced greenhouse effect but sulfur emissions are hard to produce
