There is an emphasis in the presentation on the history of work in this area, and extensive extracts from classic materials dating back to the turn of the century.
The presentation intends, very deliberately, to demonstrate the fact that radiation balance to the Earth's atmosphere is NOT merely a function of CO2 concentration. But rather extremely dependent upon water distribution, cloud formation and dissipation, the conversion of Ozone (ALWAYS formed in the upper atmosphere and ALWAYS decaying from O3 to O2, with release of the UV captured in the upper atmosphere as "heating" to the lower atmosphere...) to normal O2, and many other factors.
Mention is made of state of the art work by Dr. Hienrick Svensmark (Dutch Space/Atmospheric agency, their equivalent to our NOAA) and Dr. Roy Spencer (University of Alabama Huntsville, primary data analyst, NASA "Aqua" satellite.)
Dr. Svensmark has been elucidating the connection between sunspots, the solar wind, cosmic rays and cloud formation rates, and Dr. Spencer has been clarifying the proper "feedback" coefficient for "climate models" which will make the connection between temperature rise or fall, formation of clouds, and increase in "albedo" or reflection of incoming visible radiation. (Current climate models being used by the IPPC have ALL used "positive" feedback. Dr. Spencer has demonstrated the feedback coefficient is NEGATIVE, based on 9 years of Aqua data.)
