Introduction
Recognizing the severity of the impact of global climate change, the Intergovernmental Panel on Climate Change (IPCC) in 1 drew attention to the issue of vulnerability, which it defined as "the degree to which a system is susceptible to, and unable to cope with, adverse effects of climate change, including the variability and extremes… [it] is a function of the character, magnitude and rate of climate change variation to which a system is exposed, its sensitivity and its adaptive capacity". 2 I argue, however, that this definition needs to be expanded if we truly are to grasp what it means to be vulnerable to climate change induced effects. The definition must account not only for physical risks and resiliency, but for the capacity of societies to mitigate those risks and respond to climate change induced crises.
The need for such an expansive understanding of vulnerability is clear when we consider that discussion of climate change issues in the media and policy forums of developed nations-especially the United States and European Union-tends to focus on the potential impacts on the economies of these nations in the future. Climate change, however, already is having devastating effects on developing nations-effects that, despite being quantified; receive virtually no attention in the Western world.
The impact of climate change and physical vulnerability to its effects has been well documented globally; in particular it is intense in the lower Himalayan developing world such as Nepal and Northern India, the effects of which translate directly to the ecosystems of the lowland and coastal islands, as in Bangladesh. 1,3 Bangladesh, India, Nepal, and Pakistan already face severe problems due to rapid climate change, but these problems are utterly exacerbated by the fact that these nations are unprepared to mitigate them because of societal factors such as population growth and poverty.

climate change, vulnerability, human development, developing nations, poverty Background CIA 4 estimates show that population growth in all four of these countries significantly exceeds the global average. For example, Nepal's population is growing at the rate of 1.596 percent, followed by Pakistan 1.573; Bangladesh 1.566 and India 1.344 percent, while the global growth rate is 1.1% and the rate in much of the developed world is either stable or negative. 5 Further, we find that poverty in these four countries, as measured by the Human Development Index (HDI) and Multidimensional Poverty Index (MPI) is extensive (as shown in the table 1 below).

Review
The climate change induced problems in South Asia, a case study of Bangladesh, India, Nepal, and Pakistan  The table reveals the limitations stem from a lack of resources and their over dependence on underdeveloped technologies. In these countries climate forecasting has been very inefficient and ineffective.
Exceptional climate change has worsened the existing social and environmental problems. This has caused mass migration of both elites and agricultural workers and has yielded severe socio-economic and political ramifications. 7 The climate change induced problems "Observed physical and biological impacts of recent climate change in the developing world, especially in the tropics and sub-tropics, where substantial evidence is known to exist, but poor documentation, limited accessibility, and the sheer diversity of studies and sources has so far precluded proper scrutiny and assessment". 8 Increasing vulnerability of these South Asian nations has been widely noted. 7,9,10 For example, the UN International Strategy for Disaster Reduction (2010) identifies this region as being at the greatest risk globally with regard to climate change; Scandinavia being at lowest risk. 11 In the Germanwatch report of, 12 Bangladesh tops the list as the country at the greatest risk globally, followed by Nepal (11 th ), India (12 th ), and Pakistan (37 th ). It is no coincidence that countries at the greatest risk are characterized by high levels of poverty, dense populations, and inordinate exposure to climate-related events. These countries are dependent agriculture and prone to floods and drought. The severity and consequences of these risks can be seen vividly and tragically in terms of lives lost due to climate events over the period 1990-2009, as in Figure 1 below.
The Germanwatch Global Climate Risk Index (GCI) is an analysis based on the most reliable available data on the impacts of extreme weather events and associated socio-economic data. Thus, it only looks at one important piece in the overall, more comprehensive puzzle of climate-related impacts on socio-economic systems and, for example, does not take into account aspects such as sea-level rise or glacier melting...data only show the direct impacts of extreme weather events...The Climate Risk Index indicates a level of exposure and vulnerability to extreme events which countries should see as a warning signal to prepare for more severe events in the future. GCI ranks 172, whereas lower number in rank shows extreme risk and higher rank shows lower risk. 12 Overall scenario shows that all four countries are in the threat zone due to climate change, poverty, uncontrolled population growth, and weak mitigation options in their respective geographical locations. 1 For example, globally, Bangladesh is recognized as one of most vulnerable countries to be impacted by global warming and climate change. This is due to its unique low level of geomorphic location, dominance of floodplains, high population density, high levels of poverty, and overdependence on primary activities for survival by the majority of the population. Similarly, Nepal is the second most vulnerable country among four due to her high vulnerability to natural disasters with raising temperature in higher elevations. 13 India and Pakistan are no exceptions either. Each year natural disasters such as flood, drought, cyclone, and land slide take bring catastrophic damages taking toll of thousands of lives, houses, and large swathes of farmland. The annual monsoon rains forced reservoirs to release massive volumes of water into already burgeoning rivers, bursting banks and submerging villages and crops in low-lying areas in all four countries. 14 Though the governments of the respected countries individually and collectively are aware of this severity of the climate change impacts, and have taken some mitigation initiatives; however due to the lack of technology and economic resources coupled with poor institutional arrangements, uncontrolled population growth and ever-increasing poverty have constrained them from taking effective actions.

Conclusion
Reading the prevailing attitude in the West through media reports and public policy discussion leaves one with the distinct impression that the effects of climate change are still somewhat distant and primarily economic. As a result, while Western public dialogue about climate change often reflects serious concern, it utterly fails to capture the urgency demanded by the disastrous effects already wreaking havoc on lives and economies of developing nations-a tragically ironic situation, as the global scientific consensus points to developed nations as bearing primary responsibility for the climate change effects we are witnessing globally today. A more expansive understanding of vulnerability to climate change would promote deeper appreciation globally-but especially in the West-for the meaning and impact of climate change in real terms.
As seen in this study Bangladesh, India, Nepal, and Pakistan have been facing extreme climate change induced risks, losing property and facing human causality which are quantifiable. The people of this vulnerable zone may even need to move or migrate to safer places, which also can have an impact on social wellbeing and can create the conflicts. Clearly, climate change issues cannot be addressed in isolation. They require global cooperation and also unprecedented levels of cooperation, collaboration and resource mobilization among governments, businesses, civil society groups and communities themselves. 2 Existing mechanisms of cooperation need to develop special provisions to help the most vulnerable to mitigate climate change induced risks. 15,16 While the consequences of climate change may not be readily apparent in the developed world, in the developing world they are tragically apparent and warrant not only a heightened sense of urgency globally, but concerted and immediate action to develop plausible solutions.
