The “mainstream” climatology (MSC)—i.e. which includes the
Intergovernmental Panel on Climate Change (IPCC) community—considers the
present day massive release of greenhouse
gases into the atmosphere as the main cause of the current global
warming trend. The main inference from this stance is that the increase in temperature must occur after the release of greenhouse
gases originating from the anthropic activities. However, no scientific
evidence has been provided for this basic notion. Earth paleoclimatic records
document the antecedence of temperature over CO2 levels. For the
past 65 Ma, the temperature parameter has
controlled the subsequent increase in CO2. This includes the
three rapid aberrant shifts and extreme climate transients at 55 Ma, 34 Ma, and
23 MaREF _Ref159913672 \r \h\* MERGEFORMAT [1]. The
simple fact of their existence points to the
potential for highly nonlinear responses in climate forcing. Whatever
these shifts and transients are, CO2 remains a second order
parameter in their evolution through time. Confronted with the past, a suitable
response must therefore be given to the unresolved question of whether the CO2 trends precede the temperature trends in the current period, or not. The
assertion that the current global warming is anthropogenic in origin implicitly
presupposes a change of paradigm, with the consequence (the increase in
