Climate change refers to a statistically significant disparity in either the mean state of the climate or in its variability, persisting for an extended period of time which usually decades or longer. Climate change may be due to natural internal processes or external forcing, or to tenacious anthropogenic changes in the composition of the atmosphere or in land use (IPCC). Human activity worsen and fasten the effects of climate change.

    Greenhouse gases are transparent to definite wavelengths of the sun’s radiant energy, allowing them to enter deep into the atmosphere or all the way into the Earth’s surface. Greenhouse gases and clouds inhibit some of infrared radiation from escaping, trapping the heat near the Earth’s surface where it warms the lower atmosphere. Alteration of this natural barrier of atmospheric gases can elevate or lower the mean global temperature of the Earth (NASA). Greenhouse gas helps our world to regulate the temperature but due to the drastic amount of GHG present in our world, it becomes unbalanced and it results in the birth of climate change.

    Climate change mitigation denotes to efforts to cut or avoid emission of greenhouse gases. New technologies and renewable energies, making older equipment more energy efficient, or varying management practices or consumer behavior can mean mitigation (UN). Human activities are the main problem of GHG emission but also the human efforts will be the key to mitigate the emissions.
