Actually, only about 70% of the incident solar energy is absorbed by the Earth; nevertheless, the solar input far exceeds that which derives from the interior. Therefore geothermal energy may be ignored in dealing with the heat balance of the Earth.

Summary of climate variations,a combination of deep-sea temperature and ice sheet volume and, during periods when there were ice sheets, the data had to be corrected for this (see Figure 2.7). Deep-sea temperature dropped by about 12_C over the past 50 million years.

Book 20122nd edition to provide a long-term perspective, the first chapter briefly reviews some of the wild gyrations that occurred in the Earth‘s climate hundreds of millions of years ago: snowball Earth and hothouse Earth. Coming closer to modern times, the effects of continental drift, particularly the closing of th

Ocean sediment data, From these down-core records came a realization that the major features in marine stable isotope records were recognizable in almost all cores; and thus, if they were synchronous, these features could be used as a tool to correlate cores on a global scale.
