What is Global Warming?What is Global Warming?

1

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

2

How are human activities causing global warming?

Burning fossil fuels releases CO2 in atmosphere.

More CO2 means “thicker” atmosphere causing more heat to be trapped in the Earth’s atmosphere.

Coal burning plants produce 2.5 billion tons of CO2 every year

Automobiles create nearly1.5 billion tons of CO2 annually

1 gallon of gas produces up to 19 pounds of CO2

3

How can we reverse the effects of global warming?

We should stop pumping CO2 into Earth’s atmosphere

Economies should start using cleaner carsCountries should use more renewable energy

such as wind energy, solar energy ,hydraulic energy, geothermal energy etc.

Scientists should develop technology to cut the amount of carbon dioxide

4

Should a national 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, and economic opportunities are also ways to stop global warming

5

Should a national change policy be implemented? Why or why

not? ( cont.)

United Nations 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 they are afraid that reduction in energy could harm their economy and make unemployment worse.

6

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 greenhouse gases capture the heat

Some of the greenhouse gases are carbon dioxide ( most important one), methane (CH4), nitrous Oxide (N2O), Ozone (O3), water vapor, halocarbons

The process is called “greenhouse emission” because it is similar to the way glass traps the heat inside a green house

7

Natural green house effect makes a big deference to temperature of our earth

Without it, the average temperature is 0 degrees Fahrenheit, but with it average temperature is 50 degrees Fahrenheit

Greenhouse effect is now stronger and can trap more of sun’s energy

8

What are the impacts of global warming?The greatest impact of global warming is the

increase in extreme weather Arctic’s perennial polar ice cap is decreasing

at the rate of 9% per decade

9

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. For instance, heat waves, rising average air temperature over land and sea, warmer Springs and longer summers

Career Atmospheric scientist 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- $101,340Trends: Operational meteorologist, Climatologist,

Physical meteorologist Advancements: The American Meteorological

Society (AMS) offers the Certified Consulting Meteorologist professional certification for consulting meteorologists.

11

Career (cont.)Experienced meteorologists can advance in

supervisory and governmental jobs, or might work on more complicated forecasting jobs.

Related Careers: Environmental scientist and specialist, Geoscientist and hydrologist

High School Career academiesHigh School: River Hill High SchoolCareer 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

13

Cornell UniversityIthaca , New YorkYearly tuition of $25,185.00 for New York state

residents and $41,325.00 for non resident studentsThe program requirements are Atmospheric sciences,

Mathematics, statics, computer science, and basic physical science

In 2010,Cornell University had 13,935 under graduates, 3,179 first time degree-seeking freshman, 7,004 graduate enrollments, and 13,885 degree seeking undergraduates

14

Community ServiceVolunteered 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 that they will tell us.
