CHAPTER: 1 INTRODUCTION

  1.1      Background of the Study

 Developed and developing countries are facing serious environmental problems. The problems might be alike due to their global warming, depletion of the ozone layer and others. Global warming is a part of cyclic climate change and not manmade process. Global warming has appeared to be of different aspects to different people in different times. Once the global warming was indeed good news for the people of Northern areas. It was not until 1960s when scientists started to realize the long term hazards of global warming in terms of threat to the world supply of food and the increased level of oceans. The list of complains was enhanced by a number of categories added lately like the degradation of ecosystems and the threats to human life.

Besides climate analysts, the debate on the possible consequences gained popularity in not only economists, but also among the security experts. Until then it was impossible to put forth something concrete while keeping in mind the complexities associated with the global warming. There were issues regarding the differences of one region from others and the different impacts of humans on different parts of the world.

However, the dawn of 21st century evolved the fact that the climate changes would be harmful for the globe especially for certain regions. Some of those damages were even appearing in different parts of the world as an alarm to wake up before it is too late. It was perceived by a majority that the balance of nature will make any catastrophic situation. In case industrialization led men to some consequence, then it will be surely in mankind’s advantage. In short it was assumed then in case the damage will occur due to climate change it will affect their remote descendants and to a minor level in several centuries to come. It was not until late 1950s when scientists started to realize that the quantity of carbon dioxide (CO2) is increasing in the atmosphere suggesting that the global temperature will increase by few degrees in 21st century.

The effect of climate change on human beings’ health was in focus in 1990s.The issue was not only attracted the experts but also made the general public worried. This work was, like many other ongoing researches was supervised by not only government but also international organization like World Health Organization (WHO) and International Panel on Climate Change (IPCC).The UN Framework Convention on climate change published a shocking report in 1994 that global warming is in progress and 90% of ozone layer is destroyed.  It can be explained by the example that insect vectors of tropical diseases such as malaria and fever that has already inflicted half a billion people would expand its range. It was revealed that the impacts of global warming will be felt in developing nations where the habitants of developed world were worried about the transport of diseases to temperate zone. Many environmental related NGOs began public movement for reducing carbon dioxide emission.

Global Warming has led to the rise of Carbon Dioxide in the atmosphere, rise in the temperature of sea surface, rise in frequency of hurricanes and extent of sea ice.

Graph 1 shows the level of Carbon Dioxide in atmosphere in past 1200 Years. The increase in the level of Carbon Dioxide in atmosphere determines the Global Temperature.

Table 1.1.1 – Level of Carbon Dioxide in atmosphere in past 1200 years.

Year	CO2
800	240
1000	260
1200	280
1400	300
1600	320
1800	340
2000	360

Evidence against global warming-

According to Andrew Marshall, a global research astrophysicist, Pluto has been also experiencing Global Warming; earth is not only the planet to be experiencing the Global Warming. In May, 2006, space.com reported that a massive hurricane occurred in Jupiter caused by climate change, which is expected to rise the planet temperature by 10 degrees. In addition, National Geography news reported that climate change is a natural phenomenon as opposed to being man made. The report of NASA mentions that Mars ice caps are melting due to rise in Carbon Dioxide just like the earth. In 2004, the associated press and London telegraph reported that satellites which measure the temperature of sun light has recorded an increase in the sun’s temperature. The sun is warming up that is leading to Global Warming in the past 100 years. The increased radiation from the sun results in climatic change.
