Main source of energy for earth is sun i.e. solar energy in the form of heat. So if it continues to absorb large amount of heat and emit very less,the earth's average temperature will increase causing increase in global warming. This will also cause increase in diseases.
The main source of energy for the earth is primarily the sun. The sun emits lots of solar radiation which is observed by the earth and used in various phases of it's life cycle.
If the amount of radiation absorbed becomes more than the amount of radiated released then the average temperature of earth will increase and leading to an increase in global warming.
