There is a natural greenhouse effect, supported by the earth's carbon and water cycles, that has kept the earth warm enough for life for millions of years. Water vapour is the most significant greenhouse gas for this effect.
However, there is now an enhanced, or accelerated, greenhouse effect which is causing global warming. The most significant contributor to this enhanced greenhouse effect is carbon dioxide, caused by the human activities of deforestation and the burning of fossil fuels (oil, coal and natural gas).
What else can I help you with?
Why does concrete contribute to the greenhouse effect?
Concrete is made from cement, and the manufacture of cement releases carbon dioxide that had been sequestered underground for millions of years. Since the greenhouse effect is the result of atmospheric greenhouse gases, principally carbon dioxide, retaining heat, any increase in the atmospheric level of carbon dioxide contributes to the greenhouse effect and therefore to global warming. Because it is made from cement, concrete is an important contributor to the greenhouse effect.
What is meant by the term greenhouse effect listing the three most significant greenhouse gases?
The term "greenhouse effect" is made up of two different effects: "Natural and Man-made". There is a "natural" greenhouse effect that keeps the Earth's climate warm and habitable. There is also the "man-made" greenhouse effect, which is the enhancement of Earth's natural greenhouse effect by the addition of greenhouse gases from the burning of fossil fuels (mainly petroleum, coal, and natural gas). The three most significant green houses gases and the amount they contribute are water vapor (80%), carbon dioxide (6%) and methane (1%). Nature produces 99.7% of all green house gas emissions.
Trapping of heat in the earths atmosphere by certain gases is known as the?
greenhouse effect
What layer is most responsible for the green house effect?
The greenhouse effect is primarily caused by the presence of greenhouse gases in the Earth's atmosphere. These gases, such as carbon dioxide and methane, trap heat from the sun, leading to warming of the Earth's surface. Thus, the layer most responsible for the greenhouse effect is the troposphere, the lowest layer of Earth's atmosphere where most of the greenhouse gases are concentrated.
How much carbon is released into the atmosphere each year by fossil fuel's?
Approximately 36 billion metric tons of carbon dioxide are released into the atmosphere each year from burning fossil fuels. This significant amount of carbon dioxide is a leading contributor to the greenhouse effect and global warming.
Which single gas has the greatest impact globally on the enhanced greenhouse effect?
Carbon dioxide (CO2) has the greatest impact globally on the enhanced greenhouse effect. It is the most prevalent greenhouse gas emitted through human activities such as burning fossil fuels. CO2 is a major contributor to global warming and climate change.
An increase in the levels of carbon dioxide is the biggest contributor to what?
The greenhouse effect - Global warming.
How does the manufacture of concrete contribute to the greenhouse effect?
The use of concrete cools the planet when compared to asphalt. The albedo of concrete is better then that of asphalt or other darker materials.I guess we need to understand what we consider to be the manufacturing point.If we are discussing the actual pouring of cement, the overall effect is cooling.AnswerThe greenhouse effect is the result of atmospheric greenhouse gases, principally carbon dioxide, retaining heat. Any increase in the atmospheric level of a greenhouse gas contributes to the greenhouse effect and therefore to global warming. Concrete is made from cement, and it is when we look at the manufacture of cement that we see a real and significant contribution to the greenhouse effect. The manufacture of cement releases carbon dioxide into the atmosphere and is an important contributor to the greenhouse effect.
What planet has an atmosphere with a greenhouse effect?
EarthVenusMarsThe greenhouse effect occurs on every planet with an atmosphere (including Earth). On Venus, there is a runaway greenhouse effect causing temperatures high enough to melt lead.Mars has a greenhouse effect that is weak because of its thin atmosphere.
Are greenhouse gasses less of a problem than carbon dioxide?
Carbon dioxide is a green house gas. It is a minor contributor to the total greenhouse effect producing over 5% of all warming.
Why does concrete contribute to the greenhouse effect?
Concrete is made from cement, and the manufacture of cement releases carbon dioxide that had been sequestered underground for millions of years. Since the greenhouse effect is the result of atmospheric greenhouse gases, principally carbon dioxide, retaining heat, any increase in the atmospheric level of carbon dioxide contributes to the greenhouse effect and therefore to global warming. Because it is made from cement, concrete is an important contributor to the greenhouse effect.
What effects does deforestation have on the climate?
Deforestation is a contributor to global warming, and is often cited as one of the major causes of the enhanced greenhouse effect. Tropical deforestation is responsible for approximately 20% of world greenhouse gas emissions
Does the manufacture of concrete contribute to the greenhouse effect?

Which of the following would most likely increase the green house affect?
Burning fossil fuels, such as coal and oil, is the primary human activity that increases the greenhouse effect by releasing carbon dioxide and other greenhouse gases into the atmosphere. Deforestation is also a significant contributor as trees help absorb carbon dioxide.
