Understanding the carbon dioxide content of the early atmosphere is pivotal to under standing the mechanisms of climatic control TWO sometimes conflicting camps have put forth ideas on how this process works The first group holds that global temperatures and carbon dioxide were controlled by inorganic geochemical feedbacks; the second assert ...
