GEOG 111 1st Edition Lecture 11 Outline of Last Lecture I. Complexities of climate change (cont’d)II. Threats of climate changeIII. Indirect effects of climate changeIV. How should we handle uncertaintyOutline of Current Lecture I. Combating global warmingII. Temperaturea. Heat vs. temperatureCurrent LectureI. How much should we combat global warming?a. More warming in high latitudesb. Lots of uncertainty but undisputable/differential costsc. Side benefits of CO2 reduction:i. Only a finite amount of fossil fuels in the Earthii. Encourages development of technologies (wind power/solar power/more efficient cars)iii. Reduce CO2 emissions… you will reduce ozone (a pollutant) as wellII. Temperaturea. Heat vs. temperature1. Heat is a form of energya. Atmosphere’s strong transmissivity absorbs radiation2. Temperature is a measure of molecular activitya. The average speed of molecules or vibrations in a solidb. After applying heat to a material, temperature will rise3. Three factors that control relationship:a. Specific heat- the amount of energy required to raise one gram of a material one degrees Celsius i. Takes more energy to warm water than land (continental areas have a higher seasonal range and diurnal range than temperatures than marine areas)ii. Heating and cooling rates are inversely related to specific heatiii. Does Hatteras Island, NC or Monterey, CA have a more marine climate? Monterey, even though Hatteras has These notes represent a detailed interpretation of the professor’s lecture.
