Abstract
The dramatic and threatening environmental changes announced for the next decades are the result of models whose main drive factor of climatic changes is the increasing carbon dioxide in the atmosphere. Although taken as a premise, the hypothesis does not have verifiable consistence. The comparison of temperature changes and CO2 changes in the atmosphere is made for a large diversity of conditions, with the same data used to model climate changes. Correlation of historical series of data is the main approach. CO2 changes are closely related to temperature. Warmer seasons or triennial phases are followed by an atmosphere that is rich in CO2, reflecting the gas solving or exsolving from water, and not photosynthesis activity. Interannual correlations between the variables are good. A weak dominance of temperature changes precedence, relative to CO2 changes, indicate that the main effect is the CO2 increase in the atmosphere due to temperature rising. Decreasing temperature is not followed by CO2 decrease, which indicates a different route for the CO2 capture by the oceans, not by gas re-absorption. Monthly changes have no correspondence as would be expected if the warming was an important absorption-radiation effect of the CO2 increase. The anthropogenic wasting of fossil fuel CO2 to the atmosphere shows no relation with the temperature changes even in an annual basis. The absence of immediate relation between CO2 and temperature is evidence that rising its mix ratio in the atmosphere will not imply more absorption and time residence of energy over the Earth surface. This is explained because band absorption is nearly all done with historic CO2 values. Unlike CO2, water vapor in the atmosphere is rising in tune with temperature changes, even in a monthly scale. The rising energy absorption of vapor is reducing the outcoming long wave radiation window and amplifying warming regionally and in a different way around the globe.
Highlights
Climatic studies have reported dramatic and threatening environmental changes mainly what is known as global warming
For more than one century, the carbon dioxide was suspected and neglected as the main cause of climate changes; Geochemistry and Earth history of geologic deposits and landscapes present severe restricttions regarding the increase of weathering and, as a consequence, atmosphere CO2 capture, during cold times
The main conclusion one arrives at the analysis is that CO2 has not a causal relation with global warming and it is not powerful enough to cause the historical changes in temperature that were observed
Summary
Climatic studies have reported dramatic and threatening environmental changes mainly what is known as global warming. For more than one century, the carbon dioxide was suspected and neglected as the main cause of climate changes; Geochemistry and Earth history of geologic deposits and landscapes present severe restricttions regarding the increase of weathering and, as a consequence, atmosphere CO2 capture, during cold times. Policies were recommended to governors, based on the carbon dioxide model of atmosphere warming [1] This investigation was carried out in order to evaluate the hypothesized relationship between carbon dioxide and temperature changes. A higher CO2 pressure in the atmosphere, from independent sources such as burning forest, coal or hydrocarbon, implies an increase in CO2 pressure and up taken by water, the larger reservoir, as gas or carbonic acid These are very well known laws, the application to model CO2 flux finds many barriers because of space and time independent oscillation and scarce control points world wide
