Answer:
natural factors and human activity
Explanation:
Global warming is the gradual increase in the earth's atmospheric temperature. It is a cause of concern for every country as it affects the whole planet. Global warming is caused by the production and release of Greenhouse gases into the atmosphere.
Greenhouse gases like C02, methane, nitrous oxide etc. are gases that have the ability to trap heat energy, hence, the increased accumulation of these gases in the atmosphere leads to a rise in global temperature.
The emission of greenhouse gases, which in turn induces global warming effect, is majorly contributed by natural factors and human activities. Natural occurrences like volcanic eruption etc release these gases into the atmosphere. Also, on a large part, the emission of CO2 caused by the burning of fossil fuels is the major problem. This burning of fossil fuels is carried out by humans. Coals, petroleum and other non-renewable source of energy are used daily, which creates havoc to the environment.
Therefore, the contribution of natural factors and human activities play a huge role in global warming.
