Greenhouse Gases
Many of the challenges we face, from poverty to armed conflict, are linked to the effects of global warming and Climate Change. Now we are finding solution to the climate change problem. Some scientists are now warning that the sea level could rise by up by two meters by 2100. We must cut emissions of Green House Gases (GHGs) as well as carbon dioxide (CO2). According to the Kyoto Protocol (1997), the combination of Carbon Dioxide, Methane, Nitrous oxide, Hydro-fluorocarbons and Per-fluorocarbons sulfur hex fluoride is called Green House Gases (GHGs).The carbon dioxide accounts for more than sixty percent of total Green House Gases(GHGs) emissions. Carbon dioxide enters the atmosphere through the burning of fossil fuels (oil, natural gas, and coal), solid waste, trees and wood products, and also as a result of other chemical reactions (e.g. manufacture of cement, iron and steel production, ammonia production and urea combustions etc. Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from livestock and other agricultural practices and by the decay of organic waste in municipal solid waste landfills. Nitrous oxide is emitted during agricultural and industrial activities, as well as during combustion of fossil fuels and solid waste. The developed countries have not done much for the Most Vulnerable Countries (MVCs) which include Bangladesh. They must improve their performance in this respect.
