Document Summary

The troposphere is the region of the atmosphere involved. Temperature and climate have been changing throughout the earth"s history. Geologic records and atmospheric measurements provide information about past atmospheric temperatures and climate. The two major greenhouse gases are co2 and water vapor. Global warming temperature increases in the troposphere, which can cause climate change. Global climate change changes in any aspects of the earth"s climate, including temperature, precipitation & storm intensity that can involve global warming or cooling. The world"s floating ice and land-based glaciers are slowly melting which reflects less incoming sunlight back into space and helps warm the troposphere even more. Complex mathematical models of the earth"s climate systems have been developed that are used to project future changes in the earth"s average temperature. A warmer troposphere would have beneficial and harmful effects (see fig. 21. 14) but poor nations in the tropics would suffer the most.
