What are the causes of climate change?
Greenhouse gases
Most climate scientists agree that the main cause of current global warming is the increase in greenhouse gases from human activities, which trap radioactive heat from the Earth into space. [1] It should be noted here that the Earth's temperature The United Nations has formed an international team on climate change to examine climate change, its impacts and write reports that summarize its results. [2]
Water vapor, carbon dioxide (CO 2 ) is one of the most important greenhouse gases, and it is very small in the atmosphere. Water vapor varies according to time and place, so it is difficult to measure its average concentration globally. Active around the atmosphere, with a concentration of about 0.04%, and other greenhouse gases: methane, nitrous oxide and chlorofluorocarbons. [3]
Sources of greenhouse gases
Most greenhouse gases are emitted from burning fossil fuels in cars and factories, in electricity production, especially carbon dioxide, which is the most responsible for global warming , as well as methane emitted from landfills, agriculture, nitrous oxide emitted from fertilizers and gases used in refrigeration and industrial processes , And it is worth noting that deforestation works to keep carbon dioxide stored in the atmosphere. [2]
Natural causes of climate change
The Earth's climate can be influenced by natural factors, such as changes in volcanic activity, solar radiation reaching it, and movement of the Earth around the Sun. These factors affect the amount of energy coming into the Earth. All these causes have led to climate change in different parts of the Earth. Decrease. [4]

Hi.
it is regrettable that despite all the evidence presented in this publication governments do not do what is appropriate to reduce pollution, do you remember the treaty of kioto? Have you asked yourself if this treaty was really fulfilled? I believe that the necessary was not done to reduce the problem of global warming. How do you force China to prevent it from contaminating so much? How do you ask the United States to force the automobile companies to stop using gasoline and from now on only manufacture electric cars? Unfortunately, economic interests are more important than the global climate.
Maybe for 20 years, thanks to advances in technology, pollution could be reduced, but for now we must continue to watch passively as the most industrially powerful countries continue to pollute.
