The document discusses global warming, its causes, effects, and potential solutions. It explains that the main cause of global warming is the drastic increase in CO2 emissions from burning fossil fuels over the last 30 years. If left unaddressed, global warming will have significant effects like changes in weather patterns; rising sea levels; impacts on agriculture, plants, and animals; and consequences for human health. The document advocates addressing global warming by changing human behavior and consumption patterns, promoting reforestation to sequester carbon, and developing alternative energy sources to fossil fuels.

1. Global Warming, Greenhouse Gas Effect, Carbon Sequestration & Air Pollution By Waqas Ali Tunio Department of Mechanical Engineering, Quaid-e-Awam University of Engineering, Science & Technology, Nawabshah - Pakistan

2. Global Acceptance of GW It took more than 20 years to broadly accept that mankind is causing global warming with the emission of greenhouse gases. The drastic increase in the emission of CO2 (carbon dioxide) within the last 30 years caused by burning fossil fuels has been identified as the major reason for the change of temperature in the atmosphere

4. Global Warming More than 80% of the world-wide energy demand is currently supplied by the fossil fuels coal, oil or gas. It will be impossible to find alternative sources, which could replace fossil fuels in the short or medium term. The energy demand is simply too high.

5. Global Warming Another issue is the non-renewable characteristic of fossil fuels: It took nature millions of years to generate these resources, however we will have used them up within the next decades. Alone the shrinking supply will not make it possible to continue as usual for a longer time.

6. Global Warming Global Warming, increase in the average temperature of the atmosphere, oceans, and landmasses of Earth. The planet has warmed (and cooled) many times during the 4.65 billion years of its history. At present Earth appears to be facing a rapid warming, which most scientists believe results, at least in part, from human activities.

7. The main cause of global warming is our treatment of Nature The true cause of global warming is our thoughtless attitude to Nature. In our technology and scientific minded world, we seem to have forgotten that mankind is only a relatively minor part of Nature. We ignore being part of a larger whole.

8. Scientifically Fighting Global Warming We believe to be able to control Nature instead of trying to arrange ourselves with Nature. This haughtiness is the true main cause of global warming. As a matter of fact, some people still believe that technical solutions alone would be sufficient to fight global warming.

9. The lesson from global warming is to base all decisions on deep respect and consideration for Nature. Although we are guests on Earth, we behave as if no further visitors would arrive after us. It's like having a wild party where we destroy beds, the kitchen as well as the living room of a hotel without ever thinking about our future staying in the hotel nor about other guests arriving later.

10. The ultimate global warming solutions is to behave as part of a larger whole Many people between 20 and 65 years seem to live for the one and only purpose of earning as much money as possible in order to be able to buy as many things as possible. Someone who respects Nature and regards mankind as a part of a larger whole would never dream about using up non-renewable resources in a short time nor would this person contaminate the environment with gigantic amounts of pollution.

11. It's your personal decision whether you want to be the cause of global warming In this context the question is whether global warming and its effects will eventually wake up mankind and spark off a change of paradigm. Will we understand this hint of Nature to follow the true meaning of life or will we continue to let us manipulate by media and advertisement as sheer and willing consumers in the economic cycle? Will we continue to strive for power, prestige and possessions following the concept „the more the better "? Shall economic growth and an ever increasing personal income continue to be the reason for being here, beyond everything else?

14. EFFORTS TO CONTROL GLOBAL WARMING The total consumption of fossil fuels is increasing by about 1 percent per year. No steps currently being taken or under serious discussion will likely prevent global warming in the near future. The challenge today is managing the probable effects while taking steps to prevent detrimental climate changes in the future.

15. Let's emphasize it again: Not the others need to change, we must change ourselves. There are no international treaties or additional national laws required to start changing. We can start to change our consciousness immediately. It is really only about our personal behaviour - independent of what others do or don't do.

16. The energy that lights and warms Earth comes from the Sun. Most of the energy that floods onto our planet is short-wave radiation, including visible light. When this energy strikes the surface of Earth, the energy changes from light to heat and warms Earth. Earth’s surface, in turn, releases some of this heat as long-wave infrared radiation. THE GREENHOUSE EFFECT

17. TYPES OF GREENHOUSE GASES Greenhouse gases occur naturally in the environment and also result from human activities. By far the most abundant greenhouse gas is water vapor, which reaches the atmosphere through evaporation from oceans, lakes, and rivers.

18. Carbon Footprint The total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2). In other words: When you drive a car, the engine burns fuel which creates a certain amount of CO2, depending on its fuel consumption and the driving distance. (CO2 is the chemical symbol for carbon dioxide). When you heat your house with oil, gas or coal, then you also generate CO2

19. Hard Facts About Pollution 5000 people a day die because of dirty water 1 billion people have no access to water Nearly 1 billion going Hungary Over 50 % of grain traded around the world is used for animal feed or bio fuels 40 % of arable land has suffered long term damage Every year 13 millions hectares of forest disappear

20. Hard Facts About Pollution One mammal in 4, one bird in 3 and one amphibian in 3 are threatened with extinction. Species are dying out at a rhythm 1000 times faster than the natural rate. Three quarters of fishing grounds are exhausted in dangerous decline The average temperature of the last 15 years have been the highest ever recorded. The ice cap is 40% thinner than 40 years ago
