Has the Canadian government done a calculation to determine what atmospheric CO2 concentration constitutes DAI?
Supporting Information I have recently written two papers, which have gone through a rigorous peer-review process, that provide a simple conceptual framework for determining the CO2 concentration that constitutes dangerous anthropogenic interference, and which provide relevant scientific information needed for this determination. These two papers* are attached. It should be noted the scientific uncertainty does not mean that we cannot at present determine the CO2 concentration that is dangerous; rather, uncertainty is part of what makes increasing CO2 concentrations dangerous at some point.
