Climate Change and Sustainable Development

Global climate change is a burning issue for all over the world. It caused by greenhouse gases and ozone layer depletion. Both are two key space environmental issues of the present decade. All over the world there is growing concern about the far reaching consequences of the continuing build-up of greenhouse gases in the atmosphere and depletion of ozone layer in the stratospheric region of the atmosphere. Climate change in our environment is generated by several causes such as- population growth, pollution from industrialization, urbanization, carbon dioxide from rotting trees, the burning of coal, ozone layer depletion, natural gases and fossil fuels lead to methane travelling into the Earth�s atmosphere any transportation vehicles, water vapor, and many other little things which contribute to make global climate change even worse. The average global temperature rose by 0.74 0C during last century. This is the largest and fastest warming trend in the history of the Earth that scientists have been able to discern. Current projections show that trend will continue and will accelerate. The best estimate indicates that the Earth could warm by 3 0C during the 21st century. Therefore, science and technology education is need of 21st century for better work to safeguard environmental, social and economic wellbeing for both in the present and for future generation. Scientists are now certain that most of the change is due to human activities that emit greenhouse gases. Greenhouse gases, of CO2 are the most important, trap heat in the Earth�s atmosphere, leading to the overall rise of global temperatures, which are liable to disrupt natural climate patterns. Climate change is already having significant impacts in all over the world, particularly in developing countries, and on most ecosystems. This is based on evidence of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level. The challenge now is to develop a fairer and more effective global response to address this global problem. This requires concerted efforts by all countries, especially industrialized countries and major emerging economies, to significantly reduce the amounts of greenhouse gas emissions. Since climate change is already negatively affecting people in many areas, it is necessary to develop methods that will allow people and communities to adapt to the realities imposed by global climate change. So we can turn the graph back to normal. The start of the 21st century has found biotechnology emerging as a key enabling technology for sustainable development. Therefore, science and technology education must be need for social, environmental, economic benefits and go hand-in-hand to contribute towards sustainable development.
