According to An Inconvenient Truth, what is the role of infrared radiation in global warming?
All of the sun’s energy is converted to infrared radiation and then remains in the atmosphere. This warms the atmosphere.
Over time, infrared radiation makes the atmosphere thinner. This warms the atmosphere.
Greenhouse gases trap some infrared radiation in the atmosphere. This warms the atmosphere.
The correct answer is: Greenhouse gases trap some infrared radiation in the atmosphere. This warms the atmosphere.

Question
In which sentence below is the dashed word an indirect object?
Gore published -An Inconvenient Truth- a few years after he ran for president.
My sister gave -me- a signed copy of the book.
She said she preferred the documentary -film-.
The sentence "My sister gave -me- a signed copy of the book." contains the dashed word "me" as an indirect object.
What does Al Gore, author of An Inconvenient Truth, demonstrate about the level of atmospheric carbon dioxide levels?
Each year, the CO2 level rises and then falls. Over the past 50 years, it has steadily increased.
Each year, the CO2 level increases at a faster rate. Over the past 50 years, it has nearly doubled.
Each year, the CO2 level decreases. Over the past 50 years, it has steadily decreased.
The correct answer is: Each year, the CO2 level increases at a faster rate. Over the past 50 years, it has nearly doubled.
In the context of global warming, infrared radiation plays a significant role. According to "An Inconvenient Truth," here is a step-by-step explanation of its role:
1. The sun releases energy, including visible light and ultraviolet (UV) radiation, which reaches the Earth's atmosphere.
2. When this energy reaches the Earth's surface, it is absorbed and re-emitted as infrared radiation (also known as longwave radiation).
3. The Earth's atmosphere naturally contains greenhouse gases (such as carbon dioxide, methane, and water vapor) that allow visible light and UV radiation to pass through but absorb and trap infrared radiation.
4. As a result, some of the infrared radiation that tries to escape the Earth's atmosphere is reflected back towards the surface, contributing to the warming of the planet.
5. The concentration of greenhouse gases in the atmosphere has been increasing due to human activities, primarily the burning of fossil fuels (such as coal, oil, and natural gas) and deforestation.
6. This leads to an enhanced greenhouse effect, meaning that more infrared radiation is trapped in the atmosphere than normal, causing additional heating.
7. The overall increase in atmospheric temperatures due to this enhanced greenhouse effect is commonly referred to as global warming.
Therefore, infrared radiation plays a key role in global warming by being absorbed and trapped by greenhouse gases, which contributes to the warming of the Earth's atmosphere.
The role of infrared radiation in global warming is to contribute to the warming of Earth's atmosphere. Infrared radiation is a form of electromagnetic radiation that is emitted by the Sun as a result of its high temperature. When sunlight reaches the Earth, some of it is absorbed by the surface and converted into heat. This heat energy is then re-emitted from the Earth's surface as infrared radiation.
Normally, this infrared radiation would escape into space, but certain greenhouse gases present in the atmosphere, such as carbon dioxide and methane, can absorb and trap this radiation. As a result, the trapped infrared radiation increases the temperature of the atmosphere, leading to global warming.
To understand this concept, one can watch the documentary "An Inconvenient Truth" by Al Gore. The documentary explains the mechanisms of global warming and how increased levels of greenhouse gases, particularly carbon dioxide, contribute to the greenhouse effect by trapping infrared radiation in the atmosphere.
Additionally, scientific studies and research can provide more in-depth information and evidence on the role of infrared radiation in global warming. These sources often contain data, models, and analyses that illustrate how the interaction between greenhouse gases and infrared radiation impacts our climate.
