Stabilization Of Greenhouse Gas Concentration: A Remedy To Fight Global Warming

摘要

The concentration of greenhouse gases are increasing at a rate never seen during the last 650,000 years. This is the cause of global warming. Being very stable, their concentration can reduce if a long stabilization period is given without further increase of emissions or controlled addition of emissions. The recent report of the Intergovernmental Panel on Climate Change (IPCC), the Summary of which has been published during early 2007, has held human being mostly responsible for the present level of climate change, which may increase global mean temperature even upto 6.4 deg C and sea level upto 59 cm by 2100. This will have devastating effects, especially on developing countries which are predominantly agricultural economies dependent on water. The glaciers will melt and the snow fed rivers will become seasonal. The coastal areas will be submerged in sea and there will be unbearable economic losses to developing countries like India. The developed countries are responsible for such a situation and they must immediately take actions not only to reduce any further increase in emissions but to reduce present emissions. The developed countries are in a condition of shock as they are not willing to compromise in their present life style and the conspicuous consumption patterns. North-South dialogue on such a matter of international importance is facing road blocks. The Scientists have strongly advised to immediately reduce the further emission of greenhouse gases which are responsible for global warming. By this at least after a lapse of time, may be 100 years, the concentration of greenhouse gases in the atmosphere will stabilise at a level which is expected not to interfere with the climate system. Any delay in taking such action will delay the period of stabilisation. The paper deals with the challenges of stabilization dynamics in a "win-win" situation.
