On the significance of the shortwave CO2-absorption in investigations concerning the CO2-theory of climatic change


Hitherto absorption of solar radiation has completely been disregarded when investigating how a CO2 increase of the atmosphere modifies the earth's climate. It can be shown that shortwave and longwave influence of a higher CO2 concentration counteract each other. The temperature change at the earth's surface is ΔT=+1.2°C when the present concentration is doubled.


In den Untersuchungen über den Einfluß des atmosphärischen Kohlensäuregehaltes auf das Klima der Erde wurde bisher die Absorption kurzwelliger Sonnenstrahlung völlig außer acht gelassen. Es kann gezeigt werden, daß der kurzwellige und der langwellige Einfluß einer höheren CO2-Konzentration einander entgegenwirken. Für den Fall einer Verdopplung des gegenwärtigen Kohlensäuregehaltes wird eine Temperaturänderung an der Erdoberfläche von ΔT=+1,2°C berechnet.


Jusqu'à présent l'absorption du rayonnement solaire de courte longuer d'onde n'a pas été prise en considération dans les recherches de l'influence de la concentration du CO2 de l'atmosphère sur le climat de la terre. Il peut être démontré que les influences du rayonnement de courte et de grande longueur d'onde agissent l'une contre l'autre. La variation de la température de la surface de la terre est ΔT=+1.2°C si la concentration présente est doublée.
