A paper published back in 1998 and co-authored by Richard Tol and titled: A BAYESIAN STATISTICAL ANALYSIS OF THE ENHANCED GREENHOUSE EFFECT dealt with climate sensitivity, even though the main purpose of the paper was to demonstrate: «This paper demonstrates that there is a robust statistical relationship between the records of the global mean surface air temperature and the atmospheric concentration of carbon dioxide over the period 1870 — 1991.&raquOF THE ENHANCED GREENHOUSE EFFECT dealt with climate sensitivity, even though the main purpose of the paper was to demonstrate: «This paper demonstrates that there is a robust statistical relationship between the records of the global mean surface air temperature and the atmospheric concentration of carbon dioxide over the period 1870 — 1991.&raquof the paper was to demonstrate: «This paper demonstrates that there is a robust statistical relationship between the records of the global mean surface air temperature and the atmospheric concentration of carbon dioxide over the period 1870 — 1991.&raquof the global mean surface air temperature and the atmospheric concentration of carbon dioxide over the period 1870 — 1991.&raquof carbon dioxide over the period 1870 — 1991.»

This heat - trapping, warming influence of the blanket of air over the Earth's surface is called the greenhouse effect, and it will become even stronger as greenhouse gases such as carbon dioxide, methane and water vapor increase in concentration.

The debate over global warming centers on the extent to which gases released from the burning of fossil fuels — mainly carbon dioxide — are trapping the sun's heat in the Earth's atmosphere, creating a greenhouse effect.

Until climatologists can properly make models that reflect the entire global history and take into account plate position and how high the plates ride, oceanic levels due to this and the position of oceans, overall insolation, overall daylength and its effects on average global temperature and factor in known carbon dioxide levels over that time period, then they will be unable to give any correlation between current carbon dioxide levels and global temperature.
