What's more, according to the same computer simulations, the cumulative effect of thousands of years of human influence on climate is preventing the world from entering a new glacial age, altering a clockwork rhythm of periodic cooling of the planet that extends back more than a million years.

Further information about glacial-age floods is found in comparing the thickness and properties of sand and gravel in river valleys that were close to the former ice front with deposits more distant from the glacier.

Flint stated Croll's theory is not confirmed by geologic evidence, since there is no indication of alternation of glacial activity between the hemispheres. Besides, the calculated variations in temperature are far too small to bring about the results ... Perhaps this level of confidence about the Ice Age is temporary.
