Most theories say that global warming started since the 19th century because of the increase in the "greenhouse effect." All climatic predictions say that since human emissions of CO2 are not reduced global temperature will continue to rise. Global warming is caused by several factors such as industrialization drawbacks, greenhouse effect, and the ozone layer hole.

The first cause of global warming is industrialization. The fact that global warming started at the 19th century, which is when industrialization started, showing the relation between industrialization and global warming. Two aspect of industrialization that increases global warming are fossil fuel combustion, and deforestation. These fuels, during their combustion, tend to release a tremendous amount of greenhouse effects gases, especially CO2. These gases have causes a serious damage to our atmosphere. However...
