Video: Geophysicist explains how the Sun controls climate, not CO2
Dr. Vincent Courtillot is a professor of geophysics at the University Paris-Diderot and Chair of paleomagnetism and geodynamics of the Institut Universitaire de France. In the recent lecture below he explains how solar cycles control the climate by influence on cloud formation (the cosmic ray theory of Svensmark et al) and via influence on ocean oscillations and length of day. Dr. Courtillot notes that IPCC climate computer models do not correlate with observations and that temperature trends vary substantially between North America and Europe (which is contrary to IPCC computer model predictions).
He also notes that while the total solar irradiance (TSI) only varies by about .1% over a solar cycle, the solar UV varies by about 10% and that secondary effects on cloud formation may vary up to 30% over solar cycles. The IPCC computer models dismiss the role of the sun by only considering the small variations of the TSI and ignore the large changes in the most energetic and influential part of the solar spectrum – the ultraviolet.

Viv Evans says:
It is no surprise to me that he and his colleagues have run into the brick wall of pal review, as have so many others whose findings are not in line with the AGW crowd. His remark about his co-workers, i.e.no students because that would have a bad effect on their careers is saddening. One would wish someone of his calibre would be able to teach many a generation of young minds.
The applause for his statement about too many models and not enough observations illustrates one of the great frustrations most of us have with the model- but not reality-based AGW papers.
Personally, I fond the clarity and logic of his thoughts and presentation very refreshing, showing the great tradition of French physicists.

David L. Hagen says:
Courtillot gives a brilliant 30 min back to basics/data presentation of major correlations with solar cycles that are ignored and not explained by the IPCC models.
Enormous underestimation of uncertainties.
Temperature variations different between Eu and US.
Ocean oscillation correlates with solar cycles.
Earth Length of Day – thus winds – vary with solar cycles.
10% variation in UV; > 10% variation in EUV
Variation in atmospheric charging, currents, clouds
Highly recommend.
PS Moderator – Courtillot refers to an associated presentation by Nir Shaviv
Please post Shaviv’s presentation.
Thanks Ernest. I will view the video.

Well DUH!!!
Scientists, real scientists that is, have been saying that if there is an increase in global temps, then it may be due to the Sun and the recent increase in solar output.
Slightly off topic but an interesting link about Global Warming.

Thanks for the ping!

This is another very good article along the same lines but details further how the Sun is the controlling factor for temperature on Earth.

The Radiative Equilibrium Temperature of the Earth with the Sun.
We‟ll now get into some physics and discover that we can quite accurately predict the
radiative temperature of the Earth given just a small spattering of the laws of physics
