Document Summary

Geog 207: week 03: 0 degrees celsius = 273 kelvin, 1 degree celsius = 274 kelvin. If all heat energy emitted from the surface passed through the atmosphere directly into space, Increases in all three gases contribute to warming of earth, with the increase in co2 playing the largest role: scientists have examined greenhouse gases in the context of the past. Analysis of air trapped inside ice that has been accumulating over time in antarctica shows that the co2concentration began to increase significantly in the 19th century (see figure b3), after staying in the range of. The heat content of the ocean has increased. In the overall climate system, however, things are more complex; warming leads to further effects (feedbacks) that either amplify or diminish the initial warming: the most important feedbacks involve various forms of water. A warmer atmosphere generally contains more water vapour.
