Natural causes of climate changeThe earth has gone through warming and cooling phases in the past, long before humans were around. Forces that can contribute to climate change include the sun's intensity, volcanic eruptions, and changes in naturally occurring greenhouse gas concentrations.
Modern global warming is the result of an increase in magnitude of the so-called greenhouse effect, a warming of Earth's surface and lower atmosphere caused by the presence of water vapour, carbon dioxide, methane, nitrous oxides, and other greenhouse gases.
Global warming is the term used to describe the rising of the average temperature on Earth. It has to do with the overall climate of the Earth rather than the weather on any given day.

| Greenhouse gas | Chemical formula | Global Warming Potential, 100-year time horizon |

| Carbon Dioxide | CO2 | 1 |
| Methane | CH4 | 25 |
| Nitrous Oxide | N2O | 265 |
| Chlorofluorocarbon-12 (CFC-12) | CCl2F2 | 10,200 |
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
The biggest causes of global warming are deforestation, factories, electricity wastage, etc. Deforestation reduces the number of trees, which means there will be more carbon dioxide in the air. Factories produce a lot of greenhouse gases, and most electricity requires burning fossil fuels.
The earth's climate is influenced and changed through natural causes like volcanic eruptions, ocean currents, the Earth's orbital changes, solar variations and internal variability.
Global warming can result in many serious alterations to the environment, eventually impacting human health. It can also cause a rise in sea level, leading to the loss of coastal land, a change in precipitation patterns, increased risks of droughts and floods, and threats to biodiversity.
Factors that Influence Climate
- Elevation or Altitude effect climate. Normally, climatic conditions become colder as altitude increases.
- Prevailing global wind patterns.
- Topography.
- Effects of Geography.
- Surface of the Earth.
- Climate change over time.
So, Global warming refers to the gradual rise in the overall temperature of the atmosphere of the Earth. There are various activities taking place which have been increasing the temperature gradually. Global warming is melting our ice glaciers rapidly. This is extremely harmful to the earth as well as humans.
The two most important factors in the climate of an area are temperature and precipitation. The yearly average temperature of the area is obviously important, but the yearly range in temperature is also important.

“Global warming is a gradual increase in the earth's temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
Answer: Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth's surface.
The 'greenhouse effect' is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the 'greenhouse,' but blocking Earth's heat from escaping into space.
The global warming happens because the natural rotation of the sun that changes the intensity of sunlight and moving closer to the earth. Another cause of global warming is greenhouse gases. Once carbon dioxide increase, the temperature of earth increase and greenhouse trap the solar radiations in the earth.
