Abstract:
    Carbon dioxide (CO<sub>2</sub>), Methane (CH<sub>4</sub>) are two most potent greenhouse gases and are major source of climate change. Human activities particularly fossil fuels burning have caused considerable increase in atmospheric concentrations of greenhouse gases. CO<sub>2</sub> contributes 60% of anthropogenic greenhouse effect whereas CH<sub>4</sub> contributes 15%. Ice core records also show that the concentrations of Carbon dioxide and methane have increased substantially. The emission of these gases alters the Earth’s energy budget and are drivers of climate change. In the present study, atmospheric concentration of CO<sub>2</sub> and CH<sub>4</sub> over Pakistan is measured using Atmospheric Infrared Sounder (AIRS). Time series and time averaged maps are prepared to measure the concentrations of CO<sub>2</sub> and CH<sub>4</sub>. The results show considerable increase in concentration of Carbon dioxide and methane. The substantial increase in these concentrations can affect human health, earth radiative balance and can damage crops.
