nty in modeling climate changes during the industrial period. Aerosolsscatter and absorb short wave (solar) radiation and modify the reflectivity of clouds. Botheffects are thought to decrease the abortion of short wave radiation by the Earth, coolingthe climate, even though the troposphere aerosols only last a day in the atmosphere(Charlson). Green House Gases are related to the warming of the Earth, but the future of theclimate is not yet know, or predicted. So many variables make up the atmosphere and it'sclimate, no model can accurately predict the future. Natural Earth warmers like watervapor and clouds also contribute to the warming trend. The Earth's records of ice agesand tree rings can only paint a very small piece of this huge picture. scientist are at adisadvantage because they are not able to see the Earth's full past, as an instructor of mineonce said- they cannot predict the future of climate patterns when they have only beenstudding the atmosphere for the last 100 years....
