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.

What is the role of infrared radiation in global warming?
Infrared (IR) radiation is just as important to the Earth’s weather and climate as sunlight is. Greenhouse gases in the atmosphere, especially water vapor, “trap” (absorb and emit) some of this infrared radiation, and keep the earth habitably warm. Clouds also produce their own greenhouse effect.
What is global warming in an inconvenient truth?
Global warming is a global phenomenon caused by many things like: the accumulation of CO2 and other greenhouse gases in the earth’s atmosphere, the man’s activities e.g. air pollution from fossil fuel burning, deforestations, dumping garbage, traffic and industrial pollution and by the population (more people means
How does radiation affect global warming?
Because all objects are continually emitting radiation, the atmosphere (having absorbed the Earth’s radiation) then emits radiation, some of which is then reabsorbed by the Earth’s surface. This causes the Earth’s atmosphere and surface to be warmer than otherwise expected.
Does infrared radiation warm the earth?
It warms the surface of Earth, causing Earth to give off a radiation of its own: infrared radiation. The infrared radiation of Earth is invisible to us. Unlike the higher-energy radiation from the Sun, the low-energy, long-wavelength infrared radiation can’t pass back through the atmosphere with ease.
What is the role of radiation in the greenhouse effect?
If the concentration of greenhouse gases increases, then more infrared radiation will be absorbed and emitted back toward Earth’s surface, creating an enhanced or amplified greenhouse effect.
How does infrared radiation affect greenhouse gases?
Just like things that have temperature emit infrared radiation and cool as a result, things that absorb infrared radiation increase in temperature. So, the greenhouse gases increase in temperature, and they share that heat with the rest of the molecules in the air.
What is the purpose of an inconvenient truth?
Synopsis. An Inconvenient Truth presents in film form an illustrated talk on climate by Al Gore, aimed at alerting the public to an increasing “planetary emergency” due to global warming, and shows re-enacted incidents from his life story which influenced his concerns about environmental issues.
What is the meaning of an inconvenient truth?
According to this writer, when Al Gore refers to global warming as an “inconvenient truth” he acts as if just admitting global warming exists would help solve the problem. The writer goes on to say that even if we admit that global warming exists, we don’t know how to decrease it, or fix it.
What is the main greenhouse gas in an inconvenient truth?
Gore’s film exaggerates the rise by about 2,000 percent. Even 17 inches is likely to be high, because it assumes that the concentration of methane, an important greenhouse gas, is growing rapidly.
How does infrared radiation cause global warming a level?
When visible light and high frequency infrared radiation are absorbed by the surface of the Earth, the planet’s internal energy increases and the surface gets hotter. Some of this infrared radiation is transmitted through the atmosphere back out into space, and some is absorbed by greenhouse gases in the atmosphere.
Which type of radiation causes global warming?
INCOMING SOLAR RADIATION Larger aerosol particles in the atmosphere interact with and absorb some of the radiation, causing the atmosphere to warm. The heat generated by this absorption is emitted as longwave infrared radiation, some of which radiates out into space.
What is global warming discuss the main causes of global warming?
Global warming is an aspect of climate change, referring to the long-term rise of the planet’s temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, and farming.
Which is responsible for global warming?
Greenhouse gases The main driver of climate change is the greenhouse effect. Some gases in the Earth’s atmosphere act a bit like the glass in a greenhouse, trapping the sun’s heat and stopping it from leaking back into space and causing global warming.
What is the main reason why global temperatures have varied greatly throughout Earth’s history?
Earth’s climate has changed dramatically many times since the planet was formed 4.5 billion years ago. These changes have been triggered by the changing configuration of continents and oceans, changes in the Sun’s intensity, variations in the orbit of Earth, and volcanic eruptions.
How do greenhouse gases keep the Earth warm?
Greenhouse gases keep our planet livable by holding onto some of Earth’s heat energy so that it doesn’t all escape into space. This heat trapping is known as the greenhouse effect. Just as too little greenhouse gas makes Earth too cold, too much greenhouse gas makes Earth too warm.
