The
effect of tides is interesting since the Indian earthquake followed an eclipse
of the
sun when the tidal
forces from the moon and
sun are aligned exactly.

In fact, if the physics - based understanding
of «equilibrium sensitivity» to any
forcing is too low, then not only will CO2 have a greater
effect, so too will all other
forcings, such as: changes in the
sun, in cloud cover, in albedo, etc..
Many
of science does not include the difference in the circumference
of the equator to the poles, circular motion and the deflection
of solar energy off a moving object, the energy difference
of compression which has a huge impact to the atmosphere and under the planet's surface (centrifugal
force), the possibility
of two magnetic fields, the
force of the
sun's magnetic field in the sequence to the planets circular motion (bugs on the windshield
effect), etc. etc. etc..
To you and others like you — it may seem intuitive that when you sit a large stone saucer
of water out in the
sun, magic
forces make part
of it get colder due to green house gas
effect chaos.
But CO2 and other GHGs absorb infrared and add to the
effects of the
Sun in additional
forcings and feedbacks.
If there was a Jupiter where Mercury is, and a Jupiter where Neptune is, which would have the greatest
effect on the
Sun (in terms
of the
forces / processes which ultimately drive solar activity)?
This also explains (along with the logarithmic
forcing effect of CO2) why a runaway greenhouse didn't occur: with a dimmer
sun, high CO2 is necessary to stop the Earth freezing over.
Our climate changes because
of outside
effects, called
forcings: the
sun grows brighter, or its magnetic field changes, ocean currents shift, vegetation changes, or continents move.
(Parenthetically, if it were due to the
sun, the same would apply, but elsewhere, Dr. Curry, I, and others have cited references indicating that solar
forcing, even with some amplification beyond total solar irradiance, would have only minor moderating
effects on significant anthropogenic warming even in the case
of a severe solar lull.
Further, when they detailed different climate
forcings, the
forcing from changing solar irradiance was a trivial rounding error (though they had the good grace to mark their understanding
of this as «low») meaning the
sun has very little
effect vs. what the
sun had in 1850 (in the Little Ice Age!)
It seems that you agree that incremental Watts
of power from the
Sun and incremental Watts
of GHG
forcing power have the same
effect, relative to the surface temperatures.
I always believed that the oceans were an important element in localised weather conditions over the short term but feel that relatively sudden shifts in climate occur through external
forcings such as volcanic eruptions, meteor strike and the
effects of changes in cosmic rays and
sun spot activity, which are, unfortunately, all chaotic by nature and unpredictable.
They do not calculate body - wide tidal
forces in their paper, but look at perturbations induced by gravitational
forces directly on the inelastic material
of the
sun «locally focussed tidal
effects» if you will.
As the
Sun provides an explicit external
forcing, a better understanding
of its cause and
effect in climate change could help us evaluate the importance
of other climate
forcings (such as past and future greenhouse gas changes).
Who is to say that the
effects of the polarity reversal
of the
Sun's magnetic field (marking Solar Cycle 24's midpoint) will not act in concert with other natural
forces to amplify the
effects of the
Sun on the Earth's future climate in ways we can not comprehend?
Many don't want to believe that the environment is far bigger than us - not to say humans don't influence it, because we do, but much
of the
effect is from outside
forces outside
of human control, in particular, the
Sun.
It is simply that after accounting as best one can for the influence
of the
sun you still can't match the observed climate over the past ~ 30 - 50 years without including the
effects of additional greenhouse gas
forcing.
