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.

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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
