Possible climatic agencies in the development of post-Glacial habitats
For the meteorologist the elucidation of the reasons for past climatic fluctuations or changes must be a major scientific objective in order that he may be better placed with regard to the future. But before he can attempt a satisfactory explanation of past climatic events, great or small, he must b...

For the meteorologist the elucidation of the reasons for past climatic fluctuations or changes must be a major scientific objective in order that he may be better placed with regard to the future. But before he can attempt a satisfactory explanation of past climatic events, great or small, he must be provided with quantitative data. He must know the magnitude, the extent and the time of incidence of the phenomena. We are acutely in need of more accurate dating of the events whose effects are brought to our notice by botanical evidence. We need to know their spatial extent because we can readily think of events affecting the sun which would be likely to produce immediate reactions over the whole earth. But we can equally readily think of others, such as the freezing of the Norwegian Sea that would very rapidly affect the climate and the vegetation of the coast of Norway but would, at best, make but a slight impression on that of a distant area such as the plain of north China.
