Countries like the US, China, Japan, South Korea intent to withdraw the Paris agreement due to their indirect supports (financial support ) to the coal plants...
Our earth is covered with 1/3 with land and 2/3 with water.  Due to global warming, Greenland ice melts more rapidly, which increase the sea level, hence sea water would enter the land and there is a risk of our land to sink in the vast ocean. Though various steps are taken by UNO and other nations, to reduce global warming, still there is a risk of flooding due to the melting of ice from the polar regions.
Greenhouse gases from trees are required for the survival of living things. Greenhouse gases are water vapor, carbon dioxide, ozone, methane, nitrous oxide, chlorofluorocarbons, and hydrofluorocarbons.   Greenhouse gases trap the escaping heat in the atmosphere that surrounds our earth, similar to the greenhouse glass that traps warm air.  Nearly 50-60% of global warming is as the result of carbon dioxide emission from fuel use (such as coal), deforestation and the production of a product such as cement.
The building of the greenhouse with the glass roofing allows the sunlight to pass through to the plants inside and make the building warm and it can stay warm even during cold days of the winter season. Thermal energy is trapped in the greenhouse. The same effect is happening in the earth’s atmosphere which acts as a shield and responsible for global warming if more releases of carbon dioxide from the fuel.
On 22 April 2016, which is observed as Earth’s day, 175 world leaders signed an agreement in Paris, United Nations Headquarters to reduce the undesirable gas emissions. This was the first highest number of counties to sign an international agreement in a day. There are at present 184 countries that have with mutual consent joined the Paris agreement. But countries like the US, China, Japan, South Korea intent to withdraw the Paris agreement due to their indirect supports (financial support) to the coal plants in these countries.
