Introduction: What is Global warming? An average increase in the temperature of

the atmosphere near the Earth’s surface and in the troposphere1, which can contribute to changes in global climate patterns

Causes of global warming Burning of fossil fuels

(Coal/Crude oil) Power plants generate electricity

Transportation fuels for transports (E.g. LPG, kerosene, fuel oil)

Industrial processes (E.g. manufacture of cement, steel, aluminum)

Greenhouse gases emission Agriculture Forestry Waste management

Serious cause is Green House Effects Green house gases acts like a mirror which

reflect a part of heat radiation back to the earth.

Deforestation the state of being clear of trees. It is an activity of cutting out trees in

the forests in with the purpose of development of that particular place, resourcing the raw material to process goods like papers.

Deforestation leads to less carbon dioxide (CO2) being absorbed and causing much more of the greenhouse gases.

Effects of Global warming Sea level rising - rising at an average

rate of 1 - 2 mm/year over the past 100 years

Direct Temperature Effects - Harmful to those with heart problems, asthma, the elderly, the very young and the homeless

Climate-sensitive diseases - E.g. Malaria, dengue fever, yellow fever, encephalitis Diseases , cholera accompanying algal blooms become more frequent

Air Quality - Harmful for those with asthma and other chronic lung diseases

Food supply - Increasing risks of malnutrition

Cont… Population displacement -Rising sea levels

which increase the risk of coastal flooding UV Exposure

Skin Cancer  - an abnormal growth of skin tissues. Premature aging - make the skin thin, wrinkled,

and leathery   Cataracts  - No longer have transparent lenses in

their eyes Suppression of Immunity  

UV-B radiation weakens the immune system increases the chance of infection and disease

Resolutions For Global warming Government

set some laws to limit the amount of pollutants produced by factories

develop the skills of using renewable fuels, e.g. solar energy, wind energy

encourage the factories to replace fossil fuels by renewable fuels, which would not cause environmental pollution

carry out energy saving scheme → reduce the pollution produced by burning fossil fuels

build more plants → reduce the pollutants e.g. CO2

Citizens

reduce the use of plastic bags → as burning plastic emit CH4

recycle the resources, e.g. plastic ,

bottles .

reduce the use of air-conditioner, which will emit CFCs

use public transportation instead of private cars → reduce the pollutants emitted by cars

Conclusion The earth is too old to stand up through this phenomena. IF we want to live longer, to be safer and in good

health we must protect our environment.
