Do you disagree with the contention of the author .... Yes, In 1887 Ignatius Donnely was the victim of two errors in his premise which led him to a completly wrong conclusion. Error number one was in the age of the Earth. The premere expert in thermodynamics at that time estimated the age of the Earth at 100 million years or less since that was how long it would take a molten ball to cool to the current temperature. eas.slu.edu He did not take the unknown heating of radiation into account. The age of the earth is more than 4 billion years. The second thing that Donnely didn't know was that the continents and landmass of the Earth are moving around. ucmp.berkeley.edu As the continents drift they move from the equator to the poles and back again. They also group together in super landmasses and break apart into continental chunks. All of this greatly affects the climate that is experienced over that piece of land at any given time. Sometimes the land is on the equator where it is hot and wet, and sometimes it is near the poles where it is cold and dry, and in the meantime it is somewhere in between. The combination of Donnely trying to fit all of the wet-dry and hot cold scenarios into a few million years of time leads to his completely discredited theory of massive and frequent weather changes. In reality those changes happened much more slowly, over the course of 4 billion years, and were caused by changes in the land location not the weather. Ignatius Donnely was doomed by building his theory on fundamental errors. TP
