	--From 1958 to 1986, CO2 increased from 315 ppm to 350 ppm, which

is 1.2% per year. Fossil fuel burning has escalated much faster in recent

years than in the 1800s. Predictions are that it will reach 700 ppm during

this century if nothing is done about it. Populations and per capita

energy consumption in the Third World are increasing rapidly.

	--The problem of predicting consequences is extremely complex, but

some scientists do predict very substantial consequences within this

century.
