Votes and proceedings of the General Assembly of the state of New-Jersey . the infrared radiation fromthe earth is absorbed by the atmosphere.

Aerosols and clouds alter the energy balancebetween the earth and the and aerosols in the atmosphere re-flect and/or scatter a greater amount of thesolar radiation away from the earth atmos-phere system than would be lost from a clearatmosphere. If these conditions act alone, the declinein energy resulting from increases in turbiditywill ultimately reduce the temperature ofthe earth and atmosphere. This mechanismprovides a reasonable basis for assessing de-clining temperatures of the earth to reaching the stratosphere from Recorded changes of annual mean temperature for the northern hemisphere by Budyko and by Asakura.

When fossil fuels are burned, carbon di-oxide is released into the atmosphere. Thisrelease increases the content of COj in theatmosphere with the passage of time. Thereis observational evidence that the C02 con-tent of the atmosphere has increased by 3%since 1958 and indirect evidence that dieCO- content is currently 102 higher than in1S00. Since C02 is a good absorber of infra-red (10 ^n) radiation from the earth, in-creasing the atmospheric COj will result inhigher equilibrium temperatures. The atmosphere and the earth have at leasttwo effects working to change the overall tem-perature. One effect, increasing particle con-centration, tends to induce co
