Climate and Time in Their Geological Relations

Climate and Time in Their Geological Relations: A Theory of Secular Changes of the Earth's Climate, is by James Croll of H.M. Geological Survey of Scotland. The preface says the writer has endeavoured to give a full and concise statement of the facts and arguments adduced in support of the theory of Secular Changes of the Earth's Climate.

The text says Dr. Carpenter directs attention to the necessity of examining the broad and deep channel separating Iceland from Greenland. The text says the western half of an area is occupied by water which at the surface is flowing southwards, while the eastern half, regarded by almost everybody but Dr. Carpenter himself and Mr. Findlay as an extension of the Gulf-stream, is moving polewards. The text says that the eccentricity continuing to increase in extent, the second inter-glacial period is more warm and equable than the first, and the sea this time sinks to 2. A section headed A remarkable Circumstance regarding those Causes which lead to Secular Changes of Climate says that physical causes not only all lead to one result, an accumulation of snow and ice, but they react on one another.
