For 10,000 years, CO 2 concentration in atmosphere was around 280 parts per million. This concentration has increased since the industrial revolution and is now equal to 364 ppm. It is estimated that it will reach 500 ppm by 2100. They are likely to remain there for 100 years or more. Transportation uses more energy and produces more emissions than for industrial, agricultural, commercial and institutional uses combined.
Deforestation also increases the levels of carbon dioxide in the atmosphere.
Landfills produce 40-100 Kg of CH 4 per tonne of waste. Greenhouse gases remain in the atmosphere for a long time after they have been released. As a result, their effect on the climate continues for many years after they have been released. Global Warming A change in global temperature will have an impact on all aspects of climatic patterns, including the intensity and distribution of precipitation and winds. Besides sea level rise, an increase in global temperature is expected to have an effect on natural ecosystems.
