Abstract
Recent ice age hypotheses
Highlights
The ice ages or, to be more precise, major climate fluctuations in Earth’s history, are primarily a field of research for geologists and – as far as the last ice age is concerned – for physical geographers
Most of the ice age hypotheses do not come from geologists or meteorologists, but from the representatives of the exact natural sciences: physicists, geophysicists and astronomers
Lack imagination, rather that they have a better understanding than non-geologists of how uncertain and, inevitably, how incomplete geological facts of observation are
Summary
The ice ages or, to be more precise, major climate fluctuations in Earth’s history, are primarily a field of research for geologists and – as far as the last ice age is concerned – for physical geographers. Lack imagination, rather that they have a better understanding than non-geologists of how uncertain and, inevitably, how incomplete geological facts of observation are. They would not even dare to construct an edifice of ideas on the subject which would come from the mind of a scientist from afar (if one can put it that way), because the less one knows, the easier it is to form a hypothesis. A second reason lies in the fact that thoughts going beyond the factual often tend to come from neighbouring sciences These considerations can be expressed in another way. A diagram I published earlier, completed by 1968, indicates that we are currently in a stage of relatively active hypothesis building
