Causes of global warming:

Many factors caused global warming, and I’ am going to write about some of them.
Building structures account for about 12% of carbon dioxide emissions. Another 13% of U.S carbon dioxide emissions come from trucks used mostly for commercial purposes.

Both the above are sources of carbon dioxide which increase global warming at a higher rate. Deforestation, which is the cutting of trees, maximizes the amount of Co2 in the air due to less absorption from trees .Also the burning of fossil fuels can cause carbon dioxide to be emitted, therefore fossil fuels are also considered to be a cause of global warming.
Another cause is nitrous oxide which is a non-flammable gas. It is naturally produced from rainforests and oceans. It’s broken down in the atmosphere by chemical reactions that involve sunlight.

In conclusion, I would say that nowadays the causes of global warming are more numerous than before. All the factors I mentioned above cause serious damage and global warming. Countries should introduce strategies to reduce these causes of global warming.
