Not illustrated. 1892 Excerpt: ...no degree of eccentricity and no position of the equinox can disturb that fundamental law which asserts, that each hemisphere receives its due half of the total sunbeams of the year? It seems, therefore, hardly surprising that some should have drawn the erroneous inference that changes in the eccentricity could produce no appreciable effect on climate. Closer examination will reveal the irregularities of heat distribution which changes of eccentricity are capable of originating. At this point I have to introduce the theorem which throws much light on the subject. The demonstration cannot be obtained without the use of mathematical symbols, and I have accordingly relegated it to the Appendix; but we shall here enunciate the important result to which it leads. It being granted that a hundred is the expression for the total quantity of heat received on, let us say, the Northern Hemisphere in a year, it is required to determine the shares into which it is to be divided, if they are to represent the heat received during summer and winter respectively. At first sight it might seem that the distribution would depend upon the eccentricity of the orbit, and would also be affected by the situation in which the line of equinoxes was placed with reference to the axis of the ellipse. It fortunately happens that these elements are found to disappear in the course of the calculation. The shares into which the total heat of the hemisphere is divided between summer and winter remain unaffected both by eccentricity and by the position of the line of equinoxes. The datum in our system on which the distribution does depend is the obliquity of the ecliptic. It will be, indeed, obvious that the obliquity must form a significant factor; for if we should suppose the obliquity to b...
