Spaces added: Mikhail I. Budyko's article, "The effect of solar radiation variation on the climate of the Earth," published in 1969 was one of the first theoretical investigation of the ice-albedo feedback mechanism; i.e., the more snow and ice, the more solar radiation is reflected back into space and hence the colder Earth grows and the more it snows. Budyko notes that over the last 200 million years the temperature difference between the poles and the equator was comparatively small compared what it is today.
