  • Sadra Sepehri D block 11/6/2011 What is Global Warming?
  • Introduction
    • Global Warming is the gradual increase in the temperature of Earth
    • “ Evidence continues to build that the world is slowly but surely getting warmer.” James Hansen 
    • Earth temperature has warmed up by 1.5 degrees Fahrenheit since 1900
  • How are human activities causing global warming?
    • Burning fossil fuels release Co2 in atmosphere.
    • More Co2 means “thicker” atmosphere and that means more Co2, more heat, is trapped in the Earth’s atmosphere.
    • Coal burning plants produce 2.5 billion tons of Co2 every year
    • Automobiles create nearly 1.5 billion tons of Co2 annually
    • 1 gallon of gas is equal to 19 pounds of Co2
    • Other air pollution also cause global warming
  • How can we reverse the effects of global warming ?
    • We should stop pumping Co2 into Earth’s atmosphere
    • Economies should start using cleaner cars
    • Countries should use more renewable energy such as wind energy, solar energy, wave energy, geothermal energy and etc.
    • Scientists should use technology to cut the amount of carbon dioxide
  • Should a national change policy be implemented? Why or why not?
    • International cooperation is needed because emissions to the atmosphere circulate worldwide.
    • Benefits of climate change will be worldwide too
    • Some examples of those benefits are climate stabilization and health
    • Incentives opportunities and economic opportunities are also ways to stop global warming
    • United Nation held an earth summit in 1992 ( Rio de Janeiro)
    • All countries should agree to work together because it is something that affects everyone
    • Many countries met in Kyoto, Japan and signed an agreement called Kyoto Patrols
    • U.S and Australia haven’t agreed yet because the are afraid that reduction in energy could harm their economy make unemployment worse.
  • How does Greenhouse emission cause global warming?
    • The sun’s rays heat the earth’s land and sea and make it livable for humans and other living things
    • More than one-third of the heat bounces back off the earth’s surface but green house gases capture the heat
    • Some of the green house gases are carbon dioxide ( most important one), methane (CH4) nitrous Oxide (N2O), ozone (O3), water vapor, halo carbons
    • The progress is called “green house emission” because it is similar to the way glass traps the heat inside a green house
    • Natural green house effect makes a big deference to temperature of our earth
    • Without it average temperature is 0 degrees Fahrenheit, but with it average temperature is 50 degrees Fahrenheit
    • Green house effect is now stronger and can trap more of sun’s energy
  • What are the impacts of global warming?
    • The greatest of global warming is the increase in extreme weather
    • Arctic’s perennial polar ice cap is declaring at the rate of 9% per decade
    • Global warming doesn’t make hurricanes, but it makes them stronger
    • Rising sea level will lead to coastal flooding ( Florida, Gulf of Mexico and etc.)
    • Other great impacts of global warming are more common and intense heat waves, rising average air temperature over land and sea, warmer Springs and longer summers
  • Career
      • Atmospheric scientists mostly study the atmosphere surrounding our Earth. Also, they analyze the changes in the atmosphere that might affect the rest of our environment. For example, atmospheric scientists forecast the weather, study the weather in the past years, and examine the current weather
      • Salary : $55,150- $101,340
      • Trends : Operational meteorologist, Climatologist, Physical meteorologist
      • Advancements : The American Meteorological Society (AMS) offers the Certified Consulting Meteorologist professional certification for consulting meteorologists.
  • Career
      • Experienced meteorologists can advance supervisory and governmental jobs, or might work on more complicated forecasting jobs.
      • Related Careers : Environmental scientist and specialist, Geoscientist and hydrologist
  • High School Career academies
    • High School : River Hill High School
    • Career Academy : Allied Health Academy
    • Reason : I liked to know more information about the academy that includes Pharmacist. Pharmacist is one of the careers which might be eligible after finishing this academy
  • Cornell University
    • Ithaca , New York
    • Yearly tuition of $25,185.00 for New York state residents and $41,325.00 for non resident students
    • The program requirements are Atmospheric sciences, Mathematics, statics, computer science, and basic physical science
    • Cornell University has 13,935 under graduates, 3,179 first time degree-seeking freshman, 7,004 graduate enrollments, and 13,885 degree seeking undergraduates
  • Community Service
    • Volunteered at a nursing home
    • I think that we all should help the elderly because they were once young and helped others too. We can learn a lot of life lessons by listening to the stories they have to tell us.
