Many people consider that Global Warming is the greatestenvironmental threat of the 21st Century.

However, during the 80s and early 90s scientists arguedabout the causes and effects of global warming.

So In the late 1990s scientists reached Agreement thatglobal warming was a cause for worry .

So, why should you be concerned about global warming?

Why should we be concerned about Global

Warming?

What is the Global Warming ?

Earth is naturally insulated by a delicatebalance of heat-trapping Greenhousegases in the atmosphere.

When the sun shines on the Earth, some ofthe heat is absorbed, keeping earth warmenough to support life.

Global Warming Facts

The 1990s were the warmest decade since 1861,

when thermometer records began.

1998 was the warmest year on record.

The temperature increase of the 20th Century

was

the largest of any century in the last 1,000 years.

The ten hottest years since the beginning of the

last millennium have all occurred since 1983.

Causes of global warming

1- Natural Causes

- Greenhouse effect.

The other greenhouse gases are methane,

chlorofluorocarbons (CFCs) and nitrousoxide (N2O)

1. Methane - is released during coal-miningactivities, oil exploration and whenvegetation is burnt during land clearance

2. Nitrous oxide - comes from both naturaland man-made processes

3. CFCs - found in fridges, air conditioners,aerosols etc. are extremely effective

greenhouse gases.

2- Man-made Causes

- Carbon Dioxide ( Cars, Airplanes&

Buildings).- Burning fossil fuels.

- Population.

- Cutting Down trees.

Effects of global warming

Increase of temperature on the earth byabout 3 to 5 C (34 to 41 Fahrenheit) bythe year 2100.

Rise of sea levels by at least 25 meters(82 feet) by the year 2100

Arctic Ice Cap Will Be Gone by 2100

By 2100 Greenland Glacier Likely to beLocked Into Complete Melting

1. Effects on weather

Increasing temperature is likely to lead to

increasing precipitation but the effects onstorms

are less clear.

1. Increased evaporation

. As the climate grows warmer and thecauses of global dimming are reduced,

evaporation will increase due to warmeroceans.

1. Sea level rise

With increasing average global

temperature, the water in the oceansexpands in volume,

1. Forest fires

This releases more stored carbon into theatmosphere than the carbon cycle cannaturally re-absorb, as well as reducing

the overall forest area on the planet,creating a positive feedback loop.

1. Effect on sulfur aerosols

Sulfur aerosols, especially stratospheric

sulfur aerosols have a significant effecton climate. One source of such aerosolsis the sulfur cycle,

Solutions to the problem

- Investing in renewable energy. (wind, solar)- Plant more trees.

- Built more cool cities projects.

- Save electricity and power.

- use public transportation.

- Eat more organically grown food.

- Recycling.

- Re- think about your life style.

What are people doing to stop


20/27

What are people doing to stopglobal warming?

1. Carpooling

Carpooling is driving with someone to aplace that you are both going to. Thisminimizes the amount of greenhousegases put into the air by a car.

2. is being more careful about leaving thingsturned on

like the television, computer, and thelights.

3. Planting trees and recycling also helps

If you recycle, less trash goes to the

dump, and less trash gets burned. As aresult, there are fewer greenhousegasses in our atmosphere.

4. Watch what you buy. Many things, suchas hairspray and deodorant

now are made to have less of an impact

on the atmosphere. Less greenhousegasses will rise into the air, and globalwarming will slow down.

5. Reduce, Reuse, Recycle

Do your part to reduce waste by choosingreusable products instead of disposables.Buying products with minimal packaging(including the economy size when thatmakes sense for you) will help to reduce

waste

6. Use Less Heat and Air Conditioning

Adding insulation to your walls and attic,

and installing weather stripping or caulkingaround doors and windows can lower yourheating costs more than 25 percent, by

reducing the amount of energy you needto heat and cool your home.

7. Change a Light Bulb

Wherever practical, replace regular lightbulbs with compact fluorescent light (CFL)bulbs.

8. Drive Less and Drive Smart

Less driving means fewer emissions.

Besides saving gasoline, walking andbiking are great forms of exercise

9. Encourage Others to Conserve

Share information about recycling andenergy conservation with your friends,neighbors and co-workers, and take

opportunities to encourage public officialsto establish programs and policies that aregood for the environment

Conclusion

Making small changes in our habits can makea huge difference in our future.

In my opinion, every one on this planet musttake part and work together to find out thequickest, cheapest and most effective wayto reduce carbon emissions and overcomethis serious threat of Global Warming.
