Furthermore, it is highly unlikely that future increases in the air's CO2 content will produce any global warming; for there are numerous problems with the popular hypothesis that links the two phenomena. A weak short-term correlation between CO2 and temperature proves nothing about causation. Proponents of the notion that increases in the air's CO2 content lead to global warming point to the past century's weak correlation between atmospheric CO2 concentration and global air temperature as proof of their contention.
Carbon dioxide adds to the greenhouse gases that are warming the atmosphere. Carbon dioxide moves in and out of the atmosphere using the carbon cycle, from trees, oceans, soil and animal life.Extra carbon dioxide is now being added to the atmosphere by man burning fossil fuel, and by deforestation, removing forests that used to absorb and store carbon.arbon dioxide doesn't really hurt the atmosphere. Venus and Mars both have atmospheres comprised primarily of CO2. CO2 is also a necessary constituent of our atmosphere for â¦ plant respiration (photosynthesis) and for keeping the earth warm.
