Dr Noor van Andel spoke at the Dutch Meteorological Institute (KNMI), provocatively concluding there is no observational evidence for the influence of CO2 on past or present climate. He has released a high caliber slide set. He is the former head of research at Akzo Nobel.

In the very long run, we need not mind about CO2 or global warming, but instead about higher [galactic cosmic ray] activity and global cooling. There is no way we can influence [galactic cosmic ray] activity, originating in active black holes and imploding supernovae.
Essentially he uses empirical evidence to draw the conclusion that most recent climate variability is due to Pacific Decadal Oscillation, and to Cosmic Ray effect as described by Svensmark. This fits with what William Kinninmonth explained and I described as essentially a massive pool of “stored cold”* in the abyssal depths of the oceans, which erratically reaches up and pulls in heat from the insubstantial atmosphere above. Air temperatures are at the beck and call of the releases of this “cold” (yes I know cold is just an absence of heat). In El Nino years when the cold pool lies deep and unstirred, the incoming solar heat builds up on the surface.

With the oceans covering 70% of the planet and the clouds covering over 60% of the sky, water in its various forms, dominates our climate. Solar magnetic effects correlate with changes in clouds. This graph below shows the rise and fall over the last 1000 years. Both the Medieval Warm Period and the The Little Ice Age (upper graph) match the highs and lows of Galactic Cosmic rays (lower graph).

Cloud cover has reduced by 4% since 1984. This would account for a significant part of the warming since then. Less incoming sunlight gets blocked and reflected out to space.
