Global warming has emerged as a major concern for governments worldwide with respect to global temperature.

Global warming is primarily caused by an increase in the concentration of greenhouse gases, including carbon dioxide, methane, water vapor, and nitrous oxide, in the Earth's atmosphere. These gases act like a blanket, trapping heat from the sun that would otherwise escape into space, and causing the Earth's temperature to rise. This process is often referred to as the greenhouse effect. The increase in greenhouse gas concentrations is primarily due to human activities, such as burning fossil fuels and deforestation, which release large amounts of greenhouse gases into the atmosphere.
