Critics of this result might argue that the solar forcing in these experiments is only based on the estimated change in total irradiance, which might be an underestimate, or that does not include potential indirect amplifying effects (via an ozone response to UV changes, or galactic cosmic rays affecting clouds).

Correlations such as the cosmic - ray / cloud hypothesis are based on, are merely suggestive of such physics (although they may simply reflect a joint correlation to a third independent factor).

So Mr. Lambert puts in this skeptical view based on this research, BUT fails to ALSO comment whether CO2 has an equally significant ELECTRICAL significance, and, hence, has a dependant relationship with the cosmic ray flux.

Plotted are the period and phase (of expected peak coldness) of two extraterrestrial signals (astronomical determinations of the spiral arm pattern speed and cosmic ray flux reconstruction using Iron meteorites) and two paleoclimate reconstruction (based on sedimentation and geochemical records).

Agreed, but if it isn't CO2 [based on this absence of a temperature corrolation] then we would be wise to assume the above solar irradiance, solar UV irradiance, cosmic ray flux, Milankovitch cycles etc as being the most likely culprit.

As an alternative way, a number of (semi --RRB- empirical models are based on observations, aiming to associate cosmic - ray variations with various solar and heliospheric parameters.

My calculations show that combining heliospheric magnetic field (controlling input of the cosmic rays basis of the Svensmark's theory) with changes in the Earth's magnetic field indeed shows close correlation with the temperature variability in the N. Hemisphere on the annual, decadal and multi-decadal scale.

Well, Dr. Shaviv, having read your treatise on cosmic ray's influence on global climate based on our solar system's position in the galactic spiral arms, posted on your blog in 2006, I am wondering why you didn't get any credit for Svensmark's research.
