For example, during the Mesozoic Era, the Age of Dinosaurs, the climate was much warmer and carbon dioxide was abundant in the atmosphere. However, throughout the Cenozoic Era (65 Million years ago to today), the climate has been gradually cooling. This section summarizes some of these major past climate changes and how scientists study past climate change.

These include changes in the radiation from the Sun, changes in the tilt of the Earth, changes in Earth's orbit, changes in greenhouse gas concentrations in the atmosphere, shifts in the location of land on earth through plate tectonics, and changes in ocean circulation.
