You just quoted baloney modeling from when Hansen was putting out lies at NASA... before he was sacked.
Just about every recent relevant paper now says water vapor is what has the major impact on temps... was kicked out.
FC you pulled this boulder dash before... that article is based on climate modeling. Modeling which as all failed. I have pointed this out to you before.
from you link...
This assessment comes about as the result of climate modeling experiments which show that it is the non-condensing greenhouse gases such as carbon dioxide, methane, ozone, nitrous oxide, and chlorofluorocarbons that provide the necessary atmospheric temperature structure that ultimately determines the sustainable range for atmospheric water vapor and cloud amounts, and thus controls their radiative contribution to the terrestrial greenhouse effect. From this it follows that these non-condensing greenhouse gases provide the temperature environment that is necessary for water vapor and cloud feedback effects to operate, without which the water vapor dominated greenhouse effect would inevitably collapse and plunge the global climate into an icebound Earth state.
Is this spike in CO2 from man or not?
