9/8/2010 2 Global Climates: An Uncertain Forecast Climate Change due to anthropogenic activities Global warming – increase in temperature of the Earth’s atmosphere Greenhouse effect – natural process of lower atmospheric heating that results from trapping of incoming and reradiated solar energy by water moisture, clouds and other atmospheric gases. Change in temperature and rainfall patterns Rise in sea level Increase in heat waves More intense tropical storms http://topics.nytimes.com/top/news/science/topics/globalwarming/index.html# http://news.bbc.co.uk/earth/hi/earth_news/newsid_8972000/8972021.stm Key Terms: Global Climate World Climate Regions Weather: short-term, day-to-day expression of atmospheric processes Climate: long-term, average conditions At least 30 years of daily weather data (temperatures and precipitation) Climate regions: boundaries drawn around areas with similar average climate conditions World Climatic Region Knowledge of climate regions helps us make inferences about human activities and settlement.

Climograph: provides information on average high and low temperatures and precipitation for every month in a year Graph includes these components: Average high temperature (upper line) Average low temperature (lower line) Average precipitation (bars) Provides “Average Annual Precipitation” Climograph TERRE HAUTE, INDIANA 30-Year Normals 1971-2000 0 10 20 30 40 50 60 70 80 90 100 1 2 3 4 5 6 7 8 9 10 11 12 Degrees (F) 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 Inches Average Annual Precipitation: 40 inches

9/8/2010 4 Global Warming FIGURE 2.5 Increase in CO 2 and Temperature These two graphs show the relationship between the rapid increase of CO 2 in the atmosphere and the associated rise in average annual temperature for the world. The graphs go back 1,000 years and show that both CO 2 and temperature have been relatively stable until the recent industrial period, when the burning of fossil fuels (coal and oil) began on a large scale. Anthropogenic (human-caused)
