Presented By

Introduction
 An average increase in the temperature of the
atmosphere near the Earth’s surface and in the
troposphere, which can contribute to changes in
global climate patterns
zaeemnaqvi@hotmail.com 4
Causes
 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, aluminium)
zaeemnaqvi@hotmail.com 5
Causes
 Other greenhouse gases emission
 Agriculture
 Forestry
 Other land uses
 Waste management
zaeemnaqvi@hotmail.com 6
How serious the problem is..
 Increase ingreenhouse gases
 Concentration of greenhouse gases in the
atmosphere is highly increasing by human activities
→ Leads to the increasing seriousness of global warming
zaeemnaqvi@hotmail.com 7
Problems…
Global surfacetemperatures
 Increased about 0.6°C/century since the late 19th
century
 Increased to 2°C/century over the past 25 years
zaeemnaqvi@hotmail.com 8
Problems…
 Increasing temperature extremes
 Regions that have temperatures (1-3°C) warmer
than the average:
 United States
 Most of the Europe
 Regions that have temperatures (1-3°C) cooler than
the average:
 Australia
zaeemnaqvi@hotmail.com 9
Problems…
Sea levelrising
 rising at an average rate of 1 - 2
mm/year over the past 100 years
zaeemnaqvi@hotmail.com 10
Environmental and Human Effects
zaeemnaqvi@hotmail.com 11
zaeemnaqvi@hotmail.com 12
DirectTemperature Effects
Increase in average temperature
More extreme heat waves during the summer; Less
extreme cold spells during the winter
Harmful to those with heart problems, asthma, the
elderly, the very young and the homeless
zaeemnaqvi@hotmail.com 13
Extreme Events
 Extreme Events:
 Heat waves; Cold waves; Storms; Floods and Droughts
Global warming
An increase in the frequency of extreme events
More event-related deaths, injuries, infectious diseases,
and stress-related disorders
zaeemnaqvi@hotmail.com 14
Climate-sensitive diseases
 Increase the risk of some infectious diseases
 [particularly that appear in warm areas; are spread
by mosquitoes and other insects]
 E.g. Malaria, dengue fever, yellow fever, encephalitis
 Algal blooms occur more frequently as
temperatures warm (particularly in areas with
polluted waters)
Diseases (e.g. cholera) accompanying algal blooms
become more frequent
zaeemnaqvi@hotmail.com 15
Air Quality
An increase in the concentration of ground-level ozone
Damage lung tissue
Harmful for those with asthma and other chronic lung
diseases
zaeemnaqvi@hotmail.com 16
Food supply
Rising temperatures and variable
precipitation
Decrease the production of staple
foods in many of the poorest
regions
Increasing risks of malnutrition
zaeemnaqvi@hotmail.com 17
Population displacement
Rising sea levels
Increase the risk of coastal flooding
(Necessitate population displacement)
 More than half of the world's population now lives within
60km of the sea.
 Most vulnerable regions: Nile delta in Egypt, the Ganges-
Brahmaputra delta in Bangladesh, many small islands, such as
the Maldives, the Marshall Islands and Tuvalu.
zaeemnaqvi@hotmail.com 18
UV Exposure (Australia)
 Skin Cancer
 an abnormal growth of skin tissues.
 Premature aging
 make the skin thick, wrinkled, and leathery
 Cataracts
 No longer have transparent lenses in their eyes
zaeemnaqvi@hotmail.com 19
 Other Eye Damages
 Skin cancer around the eyes
 Degeneration of the yellow spot
 Suppression of Immunity
 Overexposure to UV radiation  suppress proper functioning
of the body's immune system and natural defenses of skin
 UV-B radiation weakens the immune system  increases the
chance of infection and disease
zaeemnaqvi@hotmail.com 20
Measures oncontrollingthe problem
zaeemnaqvi@hotmail.com 21
Solutions..
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
zaeemnaqvi@hotmail.com 22
Solutions..
 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
zaeemnaqvi@hotmail.com 23
Solutions..
Citizens
 Reduce the use of plastic bags → as burning plastic
emit CH4
 Recycle the resources, e.g. plastic
 Reduce the use of sprays → as CFCs would be emitted
out
