This presentation discusses global warming, its causes, consequences, and ways to minimize it. The causes presented are burning fossil fuels, greenhouse gas emissions from industrial and agricultural processes, deforestation, and the greenhouse effect. Consequences include ozone layer depletion, increased temperatures, ocean acidification, rising sea levels, and health impacts. Recommended measures to control global warming involve government policies like limiting pollution and promoting renewable energy and afforestation, as well as individual actions such as reducing plastic use, using public transport, and carpooling.

3. “The facts are there that we have created, man has, a self-
inflicted wound that man has created through global warming. “
-Arnold Schwarzenegger

4. ▶ 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.
Introduction

5. 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)
• Other greenhouse gases emission
– Industrial Process
• – Improper waste management
Agricultural process

6. Causes of Global warming
• Deforestation
– Forests remove and store carbon dioxide from the
atmosphere, and this deforestation releases large amounts of
carbon, as well as reducing the amount of carbon capture on
the planet.

8. With no greenhouse gases at all in its atmosphere, scientist
estimate that Earth’s average atmospheric temperature
would be about -18° C, or about 0°F.

9. The greenhouse gas content of the atmosphere is being
altered by human activity. The result of this change is globa
warming.

10. Consequences of Global warming
• Devastation of ozone layer(O3)
• A layer in earth’s atmosphere which contains relatively high
concentrations of ozone (O3 ).
Ozone absorbing Solar UV light is what heats up the
stratosphere.
▪ Effects on health
▪ It has the vital impact over the health of the people , Global warming can
intensify the problem of smog which causes lungs relating problem
▪ Similarly the exposure to UV rays can lead to the cancer related diseases

11. Consequences of Global warming
• Increase in the Annual Temperature
• One of the most obvious fact of the Global warming is that it
increases temperature around the world.

12. Consequences of Global warming
• Ocean Acidification
• As levels of atmospheric carbon dioxide (CO2) increase, the oceans
absorb some of that CO2, which increases the acidity of seawater.
Since the Industrial Revolution began in the early 1700s, the acidity of
the oceans has increased about 25 percent.
❑ Rise in Sea Level
❑ Due to the increase the temperature the glaciers and the icebergs melt which
lead to the rise in the sea level.

13. Measures on controlling the problem
• Government
• Set laws by the government to limit the amount of pollutant by the
factories
• Develop the renewable source of the energy
• Promote the afforestation

14. Measures on controlling the problem (Cont.)
• Citizen
• Reduce the use of the plastic seek for the alternative to plastic
• Avoid the use of the object like Fridge that produces the CFC
• Use the Public transport in spite of the Public vehicle
• Carpool
