# AGW theory and Fukushima nuclear disaster

by Kyoji Kimoto

The AGW theory of the IPCC was established by Dr. S. Manabe (NOAA GFDL in Princeton University) and Dr. J. Hansen (NASA GISS, Columbia University). It is theoretically failed due to the three Errors as shown below. Manabe and Hansen will be in a difficult situation when global cooling will occur with low solar activity and minus PDO index near future.

The central claim of the AGW theory can be expressed as follows, in which Planck response = 1.2K is the most basic assumption. In this essay, Planck response means no-feedback climate sensitivity obtained with the fixed absolute humidity.

Manabe & Wetherald (1967) with 1DRCM:

Climate Sensitivity=Planck response x Feedback effect (wv)

=1.3K x 1.8=2.4K

Soden & Held (2006) with fourteen 3DGCMs for AR4 of the IPCC:

Climate Sensitivity=Planck response x Feedback effects (wv, a, cl, lp)

=1.2K x 2.5=3K

Where

• wv: water vapor,
• a: albedo,
• cl: cloud,
• lp: lapse rate

Japanese government used the AGW theory to promote nuclear power in this small country where huge earthquakes and tsunamis have occurred repeatedly. In 1998, it decided to promote 20 nuclear reactors increasing the share of nuclear power over 50 % of the energy for electricity to meet the 6% CO2 cut by Kyoto protocol in 1997. The Fukushima nuclear disaster occurred in 2011 under Government policy to avoid AGW with nuclear power.

The following is the history of the AGW theory and its use in Japan for the promotion of nuclear power. Errors in red character are explained afterwards.

History

• 1967 Manabe: 1DRCM, Planck=1.3K. CS=2.4K (Error 1)

Error 1

Manabe & Wetherald (1967) utilized the fixed lapse rate (temperature decrease with height) of 6.5K/km for 1xCO2 and 2xCO2. The lapse rate of 6.5K/km is defined for 1xCO2 in the U.S. Standard Atmosphere (1962). On the contrary, the lapse rate for 2xCO2 is a parameter which needs a sensitivity analysis as shown below in Fig. 1. Since Planck response greatly changes with a minute variation of the lapse rate for 2xCO2, it is concluded that Manabe & Wetherald (1967) is theoretically meaningless.

Error 2

In 1976, Cess obtained -3.3(W/m2)/K for Planck feedback parameter λ0 utilizing the following procedure, which gives Planck response of 1.2K with the radiative forcing of 4W/m2 for 2xCO2 at the tropopause [Cess.1976].

OLR (Outgoing Long wave Radiation at the top of atmosphere) = Eeff σ Ts4

Planck feedback parameter λ0 = -dOLR/dTs = -4 Eeff σ Ts3

= -4 OLR/Ts = -3.3(W/m2)/K

Planck response = Radiative forcing/-λ0 = 4(W/m2)/ 3.3(W/m2)/K = 1.2K

Where,

Eeff: the effective emissivity of the surface-atmosphere system

σ: Stefan-Boltzmann constant

Ts=288K

OLR= 233W/m2

Cess’s procedure has been followed by many researchers including the IPCC AR4 as shown in Soden & Held (2006), furnishing the basis of IPCC’s claim that Planck response is 1.2K.

However, this procedure is apparently a mathematical error since Eeff is not a constant. Furthermore, the combination of Ts=288K and OLR=233W/m2 is not in accordance with Stefan-Boltzmann law as pointed out in Kimoto (2009).

The following Fig. 2 is the energy budget of the earth adapted from Trenberth et al. (2009).

Based on Fig. 2, Climate Sensitivity (CS) for 2xCO2 is 0.15-0.5K as shown below.

Natural greenhouse effect:          289K – 255K = 34K

Natural greenhouse energy:         Eb – Es = 333 – 78 (W/m2) = 255 (W/m2)

CS factor:                          34K/255(W/m2) = 0.13K/ (W/m2)

Radiative forcing at the tropopause:  3.7(W/m2)  [Kiehl & Ramanathan (1982)]

CS at the tropopause:               0.13K/(W/m2) x 3.7(W/m2) = 0.5K

Radiative forcing at the surface:         1.1 (W/m2)   [Kiehl & Ramanathan (1982)]

CS at the surface:                     0.13K/(W/m2) x 1.1(W/m2) = 0.15K

Error 3

Physicist Hoyt pointed out IR radiation can only penetrate the skin of 15 microns over the ocean, being reflected to the upper atmosphere. It escapes to space through the IR window of greenhouse gases absorption.  http://www.warwickhughes.com/blog/?p=87

Oceanographer Stevenson pointed out heat is dissipated to the upper atmosphere by evaporation.  http://www.21stcenturysciencetech.com/articles/ocean.html

Newell & Dopplick (1979) stated the same idea as Stevenson that the sea surface temperature does not increase due to evaporation when CO2 doubling.

In the orthodox AGW theory, heat is accumulated in the upper atmosphere instead of the ocean raising the temperature at the effective radiation height (5~8km) to recover the energy imbalance there as shown by the following figure from Fig.4 in Mitchell (1989) and Fig.1 in Held & Soden (2000).

Conclusions

The AGW theory of the IPCC was established with the bold computer simulation by Manabe and Hansen, lacking in the cautious evaluation of computed results with self-criticism mind. It has caused the following evil things to the world.

1. Fictitious science utilizing GCMs having more than 100 tunable parameters.
2. Serious economic damage.
3. Excuse for Japanese government to promote nuclear power in this small country where huge earthquakes and tsunamis have occurred repeatedly, resulting in the Fukushima nuclear disaster.

Solar activity has been the main driving force of climate change. It produced the Climatic Optimum (+2.5K), the MWP (+1K), the LIA (-1K) and the warm 1930’s (+0.5K) according to the following article:

D. Dahl-Jensen et al., 1998: Past Temperatures Directly from the Greenland Ice Sheet. SCIENCE, Vol.282, 268-271

Global cooling might occur due to low solar activity and minus PDO index near future.

Manabe and Hansen will be in a difficult situation at that time.
