While I acknowledge that the levels of carbon dioxide and other greenhouse gases in our atmosphere are increasing, that climate change is real, that human activity plays a role in these changes and that these changes are impacting our state, I simply disagree that RGGI is an effective mechanism for addressing global warming.
The causal case is a cumulative case of: 1) correlation + 2) well - evidenced mechanism (i.e. plausibility) + 3) primacy, where the proposed cause occurs before the effect + 4) robustness of the correlation under multiple tests / conditions + 5) experimental evidence that adding the cause subsequently results in the effect + 6) exclusion of other likely causes (see point 7 as well) + 7) specificity, where the effect having hallmarks of the cause (ex: the observed tropospheric warming and stratopsheric cooling, is a hallmark of greenhouse - gas - induced warming, not warming from solar forcing) 8) a physical gradient (or a dose - response), where more of the cause produces a larger effect, or more of the cause is more likely to produce the effect +....

Your point 4: «The early onset of sustained, significant warming in palaeoclimate records and model simulations suggests that greenhouse forcing of industrial - era warming commenced as early as the mid-nineteenth century and included an enhanced equatorial ocean response mechanism.
This is exactly what would be expected from surface warming mediated by greenhouse gases or any other warming mechanism.
The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse, but the way it retains heat is fundamentally different as a greenhouse works by reducing airflow, isolating the warm air inside the structure so that heat is not lost by convection.»
Regarding the earlier point, the numbers refer to the window region, where IR escapes to space with little interception from greenhouse gases, and so as the surface warms (from any mechanism) window OLR will increase.
Unlike water vapor, CO2 has no other mechanism beside its greenhouse effect by which it might cause warming.
If it does not appear as predicted, will you then accept that CO2 greenhouse effect with its concomitant feedbacks is not a major warming mechanism?

Based on an extensive literature review, we suggest that (1) climate warming occurs with great uncertainty in the magnitude of the temperature increase; (2) both human activities and natural forces contribute to climate change, but their relative contributions are difficult to quantify; and (3) the dominant role of the increase in the atmospheric concentration of greenhouse gases (including CO2) in the global warming claimed by the Intergovernmental Panel on Climate Change (IPCC) is questioned by the scientific communities because of large uncertainties in the mechanisms of natural factors and anthropogenic activities and in the sources of the increased atmospheric CO2 concentration.
When someone comes up with an experimental method that predictably and reproducibly can mathematically describe the cause / effect mechanism between greenhouse gases and CO2 then I'll believe global warming is real.
