that would make you the biggest ignoramus since Adam, right?

It has been calculated theoretically that, if there are no other
changes in the climate system, a doubling of the atmospheric CO2
concentration would cause less than 1 deg C of surface warming (about
1 deg. F). This is NOT a controversial statement -- it is well understood
by climate scientists. (As of 2008, we were about 40% to 45% of the
way toward a doubling of atmospheric CO2.)

Free Access Energy Balance Models Incorporating Transport of Thermal
and Latent Energy

Abstract
Standard latitudinally resolved energy balance models describe
conservation of energy on a sphere subject to solar heating, cooling
by infrared radiation and diffusive redistribution of energy according
to a Fourier type heat flow with flux proportional to the gradient of
temperature. The model determines the distribution of temperature with
latitude T(x). Here we consider a similar model, the two phase model,
in which we allow for transport of both thermal energy of air and
latent heat associated with water vapor.
We use the two phase model to calculate climate change, i.e., ÎT(x),
as a function of varying insolation and changing concentration of
atmospheric CO[2] under the assumption that relative humidity does not
change. We compare the results with calculations from standard energy
balance models and general circulation models. The distribution of
warming with latitude for doubled atmospheric CO[2] found with the two
phase model agrees far better with the pattern of warming found in GCM
studies than do results found with the standard model. In particular,
the two phase model, like the GCM, shows greater manning at the poles
than at the equator. In the two phase model, polar amplification can
be explained in terms of a temperature dependent effective diffusion
coefficient that increases with warming. Amplification of warming
toward the poles occurs in the two phase model because the ability of
the system to transport heat increases as the system warms.
