To understand the role of infrared radiation in global warming according to An Inconvenient Truth, we need to understand the concept of greenhouse gases and the greenhouse effect. Greenhouse gases such as carbon dioxide (CO2), methane (CH4), and water vapor are present in the Earth's atmosphere. These gases have the unique property of trapping certain wavelengths of energy, including infrared radiation, which is the type of radiation emitted by the Earth.
When sunlight reaches the Earth's surface, it warms the surface, which then radiates some of that energy back into the atmosphere in the form of infrared radiation. Normally, a portion of this infrared radiation would escape into space, allowing the planet to maintain a stable temperature. However, greenhouse gases present in the atmosphere absorb and re-emit some of the outgoing infrared radiation, trapping it within the Earth's atmosphere.
This trapped infrared radiation acts as a blanket, preventing heat from escaping and causing a warming effect on the planet. This is known as the greenhouse effect. The more greenhouse gases are present in the atmosphere, the more infrared radiation they can trap, leading to an increase in global temperatures.
It is important to note that this phenomenon of trapping infrared radiation is a natural process and necessary for sustaining life on Earth. Without the greenhouse effect, the Earth would be too cold to support life. However, human activities, such as the burning of fossil fuels and deforestation, have significantly increased the concentration of greenhouse gases in the atmosphere, amplifying the greenhouse effect and contributing to global warming.
Therefore, the correct answer is that greenhouse gases trap some infrared radiation in the atmosphere, which warms the atmosphere.
