Is the greenhouse effect caused naturally?

Answer 1

Yes, the greenhouse effect is a natural warming process. It is completely natural on any planet with greenhouse gases, including Mars, Venus and Earth.

What is not completely natural is referred to as the enhanced greenhouse effect. This is caused by man's deforestation and burning of fossil fuels (coal, oil and natural gas) which is raising the levels of greenhouse gases in the atmosphere.

Answer 2

Yes. If the green house effect did not occur then night time would be extremely cold. Life on our planet needs some degree of green house gases in order to stay alive. CO2 for example not only keeps the planet at a relatively constant temperature, but is also used in the respiration (breathing) of both plants and animals.

Answer 3

There are greenhouse effects caused both naturally, and exacerbated by man's activities.

Earth's natural greenhouse effect is caused mostly by water vapour, and to a much smaller degree, by carbon dioxide, methane, and a few other minor gases. These factors help keep the Earth warm and habitable.

The "unnatural" (or enhanced) greenhouse effect is what results from the burning of fossil fuels and deforestation. Fossil fuels release extra carbon when they are burnt, and forests are no longer there to absorb and store carbon.

Answer 4

The natural greenhouse effect (as opposed to the manmade enhanced greenhouse effect) is the warming effect of naturally occurring greenhouse gases (water vapour, methane and carbon dioxide). The presence of these gases in our atmosphere have maintained then temperature of the Earth above the temperature that would be present by simple solar radiation. Without a natural greenhouse effect, the temperature of the Earth would be about zero degrees F (-18°C) instead of its present 57°F (14°C).

Answer 5

Yes, the greenhouse effect is a natural phenomenon. It has kept the earth comfortably warm for millions of years. However, since we began burning fossil fuels (coal, oil and natural gas) at the beginning of the Industrial Revolution, more than 200 years ago, we have an enhanced (or accelerated) greenhouse effect which is causing global warming

Answer 6

The greenhouse effect is a natural process that warms the Earth's surface. It occurs when certain gases trap heat in the Earth's atmosphere, such as carbon dioxide and methane. However, human activities, such as burning fossil fuels and deforestation, have increased the concentration of these gases, leading to an enhanced greenhouse effect and global warming.

Answer 7

Yes.

CO2 is exhaled by animals, humans and plants while methane is produced by swamps, decaying vegetation and ruminant (cow) digestion, to list but a few
