We are already encountering climate crisis on our earth. In the last few decades, there have been many reports about earth changes, such as the melting of ice in polar, the rising of global sea level and the severe damage of Great Barrier Reef in Australia. The increase of Greenhouse Gas emissions in the atmosphere is considered to be the cause of increasing rate of climate change.
Our climate problem is now getting more severe. Earth surface temperature is getting warmer day by day. The amounts of CO2 emission in the atmosphere is increasing annually by human activities such as the use of fossil fuel for power generation, transportation and industrial activity that produce huge amounts of antrophogenic-CO2 emissions into the atmosphere and also deforestation activity.
