Weather of Arabia - What are greenhouse gases or greenhouse gases? What is the effect of greenhouse gases on the Earth's temperature and on the phenomenon of global warming, global warming and climate change?
What are greenhouse gases?
Greenhouse gases can be defined as gases found in the atmosphere, which absorb infrared radiation that is reflected by the earth, trapping heat in the atmosphere and preventing it from passing into space, which makes the earth warmer, which also contributes to global warming and global warming.
Factors that determine the extent to which greenhouse gases affect climate change:
People add several types of greenhouse gases to the atmosphere, and the magnitude of the impact of each gas on climate change depends on three main factors:
- amount of greenhouse gases produced.
People produce more of some greenhouse gases than others. For example, carbon dioxide is the gas that we hear people talking about the most and its impact on global warming, because we produce a much larger amount of carbon dioxide than any other gas, which makes it the most responsible for most of global warming.
- How long greenhouse gases remain in the atmosphere.
Some greenhouse gases remain in the atmosphere for only a short time, while others can remain in the atmosphere and affect the climate for thousands of years.
- The ability of greenhouse gases to trap heat.
Greenhouse gases are not equal in their ability to trap heat. For example, one pound of methane gas sequesters about 21 times more heat than one pound of carbon dioxide.
The percentage of the impact of greenhouse gases on global warming and climate change:
Carbon dioxide is the most greenhouse gas produced by humans, but there are many other greenhouse gases that contribute to global warming and climate change in different proportions as follows:
- Carbon dioxide (CO2): contributes 64.3% of global warming. It results from driving vehicles such as cars, logging, various fuel combustion operations, and some manufacturing operations. It remains in the atmosphere for 50 to thousands of years.
- Methane (CH4): contributes to 17% of global warming. It results from the decomposition of organic waste, animal digestion, fossil fuels and on the sea floor. It stays in the atmosphere for about 12 years.
- Nitrous oxide (N2O): contributes to 6% of global warming. It is produced by soil bacteria, agricultural fertilization processes, coal fuel and some production processes. It remains in the atmosphere for 114 years. Nitrous oxide traps 298 times more heat than the same amount of carbon dioxide.
- Fluorinated gases: contribute 0.8% of global warming. It results from refrigeration processes in refrigerators and air conditioners, and some manufacturing and production processes, such as the production of computer chips. Some of these gases remain in the atmosphere for thousands of years, and some trap an amount of heat approximately 23 thousand times more than carbon dioxide.
- Other gases: contribute 11.9% of global warming.
Another important greenhouse gas is water vapour.
