Document Summary

Potentially devastating issue that must be analyzed critically and objectively. Direct measurements show that they are rising. Sensitive to global temperature and precipitation patterns. Direct measurements since 1958 that co2 concentration is increasing. It never has gone up to 300 until now. In the absence of an explanatory theory, correlation between the variables don"t mean anything by themselves. Is the present rise in co2 correlated with human activity. The burning of fossil fuels involves taking ancient deposits of co2 and putting them in the atmosphere. The only way to take out co2 from the atmosphere is from decomposing matter buried in the earth. It takes thousands of years for co2 to even be deposited back into the atmosphere.
