The Global warming gases are increasing steadily in the world due to the advent of industrialization. In 1800 before the industrial revolution started, the concentration of CO2 gas in the atmosphere was estimated to be 260 ppm only. The concentration of CO2 in the year 1988 was observed in Hawaii to be 350 ppm. The data indicate that the rate of concentration of global warming gases (GWG) in the atmosphere has increased considerably in the past few decades. This pushes the average global surface temperature by about 0.7°C. The United Nations Intergovernmental Panel on Climate Change (IPCC) has taken the view that average global temperature could rise by 1.4°C-5.8°C by the end of this century. This paper discusses some aspects of global warming and the role of admixtures in reducing emissions of CO2 to the atmosphere.

Abstract


The Global warming gases are increasing steadily in the world due to the advent of industrialization. In 1800 before the industrial revolution started, the concentration of CO2 gas in the atmosphere was estimated to be 260 ppm only. The concentration of CO2 in the year 1988 was observed in Hawaii to be 350 ppm. The data indicate that the rate of concentration of global warming gases (GWG) in the atmosphere has increased considerably in the past few decades. This pushes the average global surface temperature by about 0.7°C. The United Nations Intergovernmental Panel on Climate Change (IPCC) has taken the view that average global temperature could rise by 1.4°C-5.8°C by the end of this century. This paper discusses some aspects of global warming and the role of admixtures in reducing emissions of CO2 to the atmosphere.
