No significant correlation between CO2 increases

and human caused annual CO2 emissions (P>0.10).

A multiregression statistical analysis show:

A highly significant correlation between temperature anomalies and annual CO2 increases (P<0.0001)

There are primarily three factors controlling the CO2 level in the atmosphere due to

the atmopshere-ocean surface equilibrium process

1. The ocean water surface temperature and its correlated surface area. During ice ages the ocean surfaces are also reduced and a larger ice area reduces the albedo factor. Changes over long time cycles due to ocean currents

There are basically three factors controlling the CO2 level in the atmosphere

1. The ocean water surface temperature and its correlated surface area.2. Annual seasonal changes of ocean water temperatures

What about the human CO2-emissions?

Today human emissions are 1% of the total CO2 content in theatmosphere

Considering that the annual turnover of CO2 with oceans andBiomass is 25% of all CO2 in the atmosphere the annualhuman contribution is insignificant

The amount of CO2 dissolved into the oceans are determinedby the ocean surface temperature to reach equilibrium with atmosphere

Page 28: Goldberg CO2

In 1991-1992 as a result of the Pinatubo eruptionthe Earth cooled almost 1 C.

The increase of CO2 in the atmosphere was 1,47 ppm or 3 Gton C

At the same time human emissions were 12,5 Gton C.

Where did the remaining 9,5 Gton C go?

Most of it was dissolved into the oceans due to colder water

Encircled values selected by Callendar made an average 19th century CO2

concentration of 290 ppmv.

IPCC models show that the total greenhouse effect ofCO2 and other gases in addition to

particles and aerosols, will result in a heating of the atmosphere at

8.000-12.000 m altitude

Page 43: Goldberg CO2

MSU and balloon measurements show no warming

Increasing CO2 leads to a very limited green-house effect following a logaritmic deacreasing curve

A doubling of 1900 level of 290 ppmleads to a temperature increase of1,2 C
