Scientist: Climate changes are not caused by greenhouse gases


Dr. Noor van Andel, former head of research at Akzo Nobel, has a new paper out showing the available data to date contradicts the notion of greenhouse gas induced global warming or ‘climate change.’ He notes that while there have been extensive efforts to ‘prove’ the ‘greenhouse’ warming theory by bringing computer models and observations into agreement, this has been done “strangely only by adjusting the measurements instead of adjusting the models,” in other words, via unscientific means. Dr. van Andel instead finds that ocean oscillations and the cosmic ray theory of Svensmark et al best explain climate changes.

CO2 and climate change
Noor van Andel,, 17-01-2011.

Abstract: It is shown that tropical Pacific sea surface temperature anomalies are closely congruent to global temperature anomalies, and that over more than a century. When we understand the cooling mechanism over the tropical Pacific, and especially its CO2 dependency, we can draw conclusions for the global CO2 climate sensitivity.

It is shown that the cooling of the tropics, or trade wind belt, is by deep convection, i.e. by a few thousand concentrated tropical thunderstorms that carry all the sensible and latent heat swept up by the trade winds all the way on to the tropopause. The physics of deep convection have been formulated since 1958 and are based on sound thermodynamics and measurements on location.

The trends of the temperature in the high atmosphere in the last half century are very negative, starting on this height where the convection reaches. That means that more CO2 has a cooling effect rather than a warming effect. Cloud tops radiate much more intense than the thin air on this height. This is the cause behind the cooling, as much as the CO2 increase.

The cooling trend is quite in discrepancy with the ?greenhouse-gas-induced-global-warming? theory, but is quite in accord with increasing deep convection. The adjustment of these temperature measurements to bring them more in line with the climate models leads to unphysical conditions and processes. The response of the upper atmosphere temperature on volcanic eruptions also fits in the deep convection theory, but not in the mainstream theory.

Not CO2 increase, but two other parameters are the cause of climate change: ENSO or El Niño Southern Oscillation, a large change in the cold water upwelling along the coast of South America correlates well to short term climate change, and change in the intensity of hard, deeply penetrating Galactic Cosmic Radiation, well documented by 10Be deposits and 14C levels, correlates very well with long-term climate change including ice ages.

My conclusion is that climate changes are not caused by greenhouse gases.

selected excerpt from the paper:

The global warming started in 1976 with the ?big climate shift?, the trend stopped in 1999 but the climate stayed warm until 2010. We see that in the warming period 1079-2009 not only the warming trend at the surface is higher, but the cooling trend in the high tropical troposphere is more clearly enhanced. We see even a cooling trend 1979-2009 replacing a warming trend 1958-2009 at the tropical 500-800 hPa height. We could even conclude that more CO2 cools the climate, because it cools the upper regions where the deep convection reaches, increasing the effective lapse rate over the whole height with 0.35 K/decade, over 2 decades and 12 km that means 0.07*2/12=0.012 K/km, not much, but we see in the table that a 0.1 K/km lapse rate increase at SST -302K increases the convection top 1.5 km. So this CO2 cooling trend over 2 decades brings the convection top 1.5 km/0.1*0.012=180 m higher, which is not negligible.

This behavior has been a problem for many, as it contradicts the global-warming-by-greenhouse- gases theory. So there has been a large activity to bring models and observations into agreement, strangely only by adjusting the measurements instead of adjusting the models.

and from the paper’s conclusion:

Our present climate is due to an increased length of the last interglacial period, more than 10000 years, due to a low level of GCR [galactic cosmic rays] that maintains a low cloud cover, a low albedo, more absorbed sunshine and a pleasant climate. In the very long run, we need not mind about CO2 or global warming, but instead about higher GCR activity and global cooling. There is no way we can influence GCR activity, originating in active black holes and imploding supernovae.
