What Are The Main Points Of Global Warming?

Global warming theory is a big threat to the planet earth and its living organisms. Global warming is the increase in the average temperature of earth and is marked by extreme climate changes. The adverse effect of the global warming theory is the melting of polar ice regions which might result in floods and increase in the temperature causing more hot weather in certain regions of the world. The cycle of weathers can be disturbed which can affect the natural resources and living patters if global warming continues to prevail.  The global warming will increase the sea levels, affect precipitation process, expansion of desert regions, extinction of some species, agricultural disasters etc.
