Global warming in simpler terms is an increase in the overall temperature of the Globe. When we talk about the global level, even a 1-degree temperature increase can cause an adverse effect on the environment. The main reason behind global warming is the increase in greenhouse gases which are, carbon-di-oxide, methane, etc. Due to their accumulation, solar heat reaching earth is unable to escape and gets trapped within the surroundings leading to an overall increase in the global temperature and ultimately causing global warming.
