Unfortunately
for policymakers and the public, while the basic science pointing to a rising human influence on climate is clear, many of the most important questions will remain surrounded by deep complexity and uncertainty
for a long time to come: the pace at which seas will rise, the extent of warming from a certain buildup of greenhouse gases (climate
sensitivity), the impact on hurricanes, the particular effects in particular places (what
global warming means
for Addis Ababa or Atlanta).
When modelling the effect on
global temperature, they are using the equivilant of 3.18 deg C equilibriom
sensitivity which is par
for the course.
Narrowly scoped, the present situation is either strictly caused by solar variations (in which case I believe the «solar variation» crowd will inappropriately gain credibility over the next 10 to 20 years as we work through the next below average solar cycle or two), or strictly caused by CO2 concentrations (in which case I believe the «CO2 concentrations» crowd will inappropriately lose credibility as the non-linear relationship (
sensitivity is based on doublings, not linear increases) between increased CO2 concentrations, and forecasts
for below average solar cycles reduces the longer term upward trend in
global temperatures).
The obvious answer (from someone who is indeed receptive to arguments
for lower - than - consensus climate
sensitivities) is that it was on a par with recent hot years because temperatures at US latitudes of the globe really weren't as much cooler in the 1930s / 1940s (compared to the present) than GISS / Hadley's best estimates (from often sketchy
global coverage) suggest.

(This large uncertainty essentially due to the uncertainty in the aerosol forcing; it is also the main reason why the magnitude of

Climate
sensitivity is a measure of the equilibrium
global surface air temperature change
for a particular forcing.
Nonetheless, there is a tendency
for similar equilibrium climate
sensitivity ECS, especially using a Charney ECS defined as equilibrium
global time average surface temperature change per unit tropopause - level forcing with stratospheric adjustment,
for different types of forcings (CO2, CH4, solar) if the forcings are not too idiosyncratic.
In this case the CO2 concentration is instantaneously quadrupled and kept constant
for 150 years of simulation, and both equilibrium climate
sensitivity and RF are diagnosed from a linear fit of perturbations in
global mean surface temperature to the instantaneous radiative imbalance at the TOA.
(PS we are considering the climate
sensitivity to be in terms of changes in
global - time average surface temperature per unit
global - time average radiative forcing, though one could also define other
sensitivities for other measures of climate).
I sincerely hope that you are not serious in maintaining the following: The peak warming is linearly proportional to the cumulative carbon emitted It doesn't matter much how rapidly the carbon is emitted The warming you get when you stop emitting carbon is what you are stuck with
for the next thousand years The climate recovers only slightly over the next ten thousand years At the mid-range of IPCC climate
sensitivity, a trillion tonnes cumulative carbon gives you about 2C
global mean warming above the pre-industrial temperature.
So my question is: are there any other papers I should look at
for a realistic estimate of the
sensitivity of
global temperature to the solar cycle?
Over very long time periods such that the carbon cycle is in equilibrium with the climate, one gets a
sensitivity to
global temperature of about 20 ppm CO2 / deg C, or 75 ppb CH4 / deg C. On shorter timescales, the
sensitivity for CO2 must be less (since there is no time
for the deep ocean to come into balance), and variations over the last 1000 years or so (which are less than 10 ppm), indicate that even if Moberg is correct, the maximum
sensitivity is around 15 ppm CO2 / deg C. CH4 reacts faster, but even
for short term excursions (such as the 8.2 kyr event) has a similar
sensitivity.

for the man - made
global warming theory to be incorrect, climate
sensitivity must be low (see Climate Sensitivity: The Skepti
sensitivity must be low (see Climate

I have since shown that your assumption here was wrong, and that the premise was IPCC's own climate
sensitivity assumption of 3.2 C (and scenario B1
for CO2 increase without this
global carbon shutdown).

Their reconstructed CO2 concentrations
for the past five million years was used to estimate Earth - system climate
sensitivity for a fully equilibrated state of the planet, and found that a relatively small rise in CO2 levels was associated with substantial
global warming 4.5 million years ago.
The climate
sensitivity is defined as the equilibrated change in
global mean surface air temperature (SAT)
for a given change in radiative forcing and has been a major focus of climate research over the last three decades.
