Why is global warming known as the greenhouse effect?

Answer 1

A greenhouse gas is any gas, such as carbon dioxide, or methane, that traps large amounts of heat from the sun in an atmosphere. Global warming takes place when these greenhouse gases accumulate in the atmosphere which makes the average temperature on Earth warmer.

A:The greenhouse effect is the process by which greenhouse gases keep the earth warm, or raise its temperature. The normal greenhouse effect is a natural phenomenon that occurs when atmospheric carbon dioxide concentrations are in the range of 260-280 parts per million (ppm), thereby maintaining a comfortable global climate suitable for human existence. Some scientists suggest 350 ppm may be the maximum sustainable CO2 level.

The atmospheric carbon dioxide concentration has recently risen above 390 ppm, and continues rising at an exponential rate. Since carbon dioxide is a greenhouse gas, this rise results in global warming and climate change.

The difference between the normal greenhouse effect and what contributes to global warming are the increasing carbon dioxide concentrations as a direct result of human activities, such as burning fossil fuels (oil, coal, and natural gas), as well as deforestation and cement manufacture.

Answer 2

Global warming is not known as the greenhouse effect.

The greenhouse effect is the way the greenhouse gases in the atmosphere hold in the sun's heat and keep the earth warm. The earth's carbon cycle and water cycle have been keeping this balanced for millions of years, releasing and absorbing carbon dioxide and water vapor.

How the greenhouse effect works:

The atmospheric greenhouse effect heats the earth because greenhouse gases are transparent to short wave thermal radiation from the sun, but are opaque to the long wave infrared radiation which is re-emitted. These absorb outgoing infrared radiation and re-emit some of it back towards earth, caused a heating effect.

The enhanced greenhouse effect (or accelerated greenhouse effect) is the warming effect caused by all the extracarbon dioxide greenhouse gas that man has put into the atmosphere in the past 250 years by burning fossil fuels (coal, oil and natural gas).

Global warming is the warming of the earth because of this enhanced greenhouse effect.

Answer 3

The greenhouse effect is called the greenhouse effect because the atmosphere acts as a greenhouse in the way that when the suns rays shoot down to earth they cannot get out of the atmosphere because the fuels that are being put into our atmosphere acts as a shield or a wall not letting the suns rays out. Just as a greenhouse does not let the sun's energy out.

Answer:

The popular view is that the atmosphere has some sort of layer of carbon dioxide "up there" that reflects heat back down to Earth rather than letting it escape to space. That would be like the glass on a greenhouse trapping warm air inside while letting the sunlight through to increase the heat. In a greenhouse the sunlight warms the benches and floor, the warm objects heat the air, the air is trapped by the double layer of insulating glass.

It does not happen that way in the Earth's atmosphere.

Sunlight comes in and warms the Earth's surface. It warms the gases in the air too, at least some of them with a bond size that gets excited by sunlight. These special gases are greenhouse gases (carbon dioxide, methane, water vapour and a few others). They are mixed evenly through all of the atmosphere (not in layer). When the gases are warm they share their heat with all their gas molecule neighbour and heat the atmosphere generally.

The effect is more like wet sand in a microwave. Microwaves do not heat sand. They do heat water. When you microwave wet sand, the water heats up - might even turn to steam. The hot water warms the sand.

Answer

greenhouse effect get its name because some of the sun's heat energy passes through the atmosphere and is absorb by the Earth. some heat energy is reflect by the atmosphere back into space or is reflected back downward by the atmosphere to EARTH, that what happen to the energy that is reflected by EARTH.

Answer 4

The greenhouse effect, which is the way the greenhouse gases warm the atmosphere, is causing global warming (because humans have added extra carbon dioxide into the atmosphere by burning fossil fuels).

Answer 5

Carbon dioxide is called a greenhouse gas because it acts somewhat like a greenhouse in keeping the earth warm. Solar radiation, re-radiating out from the surface of the earth, is captured by greenhouse gases (essentially any gas with more than two atoms). This warmth is held in the atmosphere, now causing global warming.

Answer 6

Global warming is known as the greenhouse effect because it is caused by the trapping of heat in the Earth's atmosphere, similar to how a greenhouse traps heat to create a warm environment for plants to grow. Greenhouse gases such as carbon dioxide and methane act like a blanket, allowing sunlight to enter the atmosphere but preventing some of the heat from escaping back into space.

Answer 7

Human activities. Mainly extracting and burning fossil fuels.
