Understanding Tropical Climate Change from geological perspectives through multi-dimensional approach
Climate Change is a serious global environmental concern and is one of the complex problems facing mankind today. It is primarily caused by the building up of Green House Gases (GHG) in the atmosphere. The global increases in carbon dioxide concentration are due to primarily fossil fuel use and land use change, while those of methane and nitrous oxide are primarily due to agriculture. Nevertheless climate change is a complex system having variety of components which play significant yet intriguing role. Understanding such a complex issue with vast and varied dimensions and implications, assumes greater significance for all stakeholders, especially from tropical regions in general and Indian perspectives in specific. Climate change is impacting the natural ecosystems and is expected to have substantial adverse effects in India, mainly on agriculture on which 58 per cent of the population still depends for livelihood, water storage in the Himalayan glaciers which are the source of major rivers and groundwater recharge, sea-level rise, and threats t o a long coastline and habitations. Climate change will also cause increased frequency of extreme events such as floods, and droughts. These in turn will impact India’s food security problems and water security. Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level. Therefore, there is an imperative need to discuss various cross cutting issues of climate change involving multi-dimensional multi-disciplinary approach to evolve appropriate response to meet the emerging challenges of climate change. Climate change is not an isolated issue. It has several aspects and inter-linkages namely, science and technology, economy and trade, diplomacy and politics - that makes it not just another issue in this complicated world of proliferating issues, but the mother of all issues. Climate change refers to the variation in the Earth’s global climate or in egional climates over time. It describes changes in the state of the atmosphere over time scales ranging from decades to millions of years and therefore demands to bring synergy among various experts with geologists to understand climate system with a holistic view . In the proposed symposium experts of varied filed having goal to understand climate change shall be invited for detailed deliberations.
