CLIMATE CHANGE IN SIMPLE TERMS

As of last year, our atmosphere consisted of 78% nitrogen, 21% oxygen and 1% trace gases, including carbon dioxide.  Although the measurement of carbon dixoide (CO2) in the atmosphere is very low, 0.038% in 2010, it can fluctuate slightly with the change of seasons, water vapors, El Nino and sun flares.  Volcanos and forest fires also emit small amounts of CO2.

We need CO2.  Why?  It is absorbed by all vegetation and is used for photosynthesis and other organic compounds needed for plant development.  Some plants are used for food, of course, but we all need the oxygen they emit.  ~~Data compiled from a column by Bill Conry in The Canon City Daily Record.  Thanks Mr. Conry
