Abstract
IPCC claims that Global Warming is caused more or less exclusively by
anthropogenic emissions of CO2. Therefore, only a total stop of these
emissions could avoid a disaster. In IPCC’s reasoning, two concepts are
central: The “constant airborne fraction”, according to which about 50
% of all anthropogenic emissions remain in the atmosphere, whatever the
emissions and whatever the concentration, and the “fixed carbon
budget”, which is the maximum amount humans may emit, when Global
Warming should stay below a given limit, independent of the temporal
distribution of the emissions. In this article, it is shown that three
prerequisites must be fulfilled for these two central concepts to be
viable: All natural sources of CO2 must have remained constant, the
short-term partners of the atmosphere must store the same amount of CO2
as the atmosphere itself, and the atmosphere together with its
short-term partners must be a closed system. And it is shown with high
confidence that, according to the rules of physics, all three are not
fulfilled. If this were confirmed, it would have a serious impact on the
entire climate debate. A careful review seems to be needed urgently.
