Of green and not-so-green thoughts
Who guessed that it could be so simple?All measurements point to the average global temperature TREND since 1610 (the start of regular recording of sunspot numbers) being driven by something(s) that are driven by the sunspot number time-integral. OSCILLATIONS above and below the trend are the net effect of ocean cycles. Since temperatures have been accurately measured world wide, the net effect of ocean cycles has been very nearly ±1/5 K with a period of 64 years. Most recent peak was in approximately 2005.Aerosols, volcanos, change to the level of atmospheric carbon dioxide, etc. have had no significant effect on average global temperature.All this is shown at http://conenssti.blogspot.com/ and sub links.
