The pollution has caused the ozone hole. UVA rays are sent to the Earth from the sun, bouncing on the ground and become Infrared are returned to the atmosphere but they can't go outside because they find the layer of smog and remain imprisoned warming Earth's surface. This is the “ Greenhouse effect”

Consequently, the glaciers melt and flood coastal areas and increase flooding seaside city like Venice. The area of glaciers in the North Sea has been reduced by almost 10%.

A few of mountains between 1850 and 1980 have lost about a third of their surface and half of their mass. (The Dolomites Marmolada glacier has lost Within a few years about 16 meters extension).

The hot and salt water leaves the Mexico’s Gulf and arrives at the North Pole, during the way the water evaporates so its density grows, and it starts to go downward. For that reason the water is getting cold and it’s going down until it changes rout. If the melting of glaciers makes much fresh water, the salt water will not grow the density and will not go downward, so the Gulf Stream will be stopped.
 Furthermore the increase of temperatures will lead to an increase of force 4 and 5 cyclones and typhoons and as has already been seen, in the last thirty-five years temperatures have doubled.

 Droughts, floods and temperature increases will be ideal conditions for tropical infections.

     Animals and plants will experience enormous difficulty to adapt to climatic changes and many species will die out. The amount of water in the oceans will increase and the salt water percentage will rise, killing many species of fish and thus breaking the food chain of the entire planet.
