What is the function of the natural greenhouse effect?

Answer 1

The Earth would be a much colder place without the heat trapping effect of CO2 and methane, and life would probably never have evolved without it. The recent increase in greenhouse gasses is something we don't need, though. So,we need it to keep us warm.

Answer 2

green house effect is one of the most important phenomenon for life on earth. Now,what does green house effect does? it traps the heat and helps to maintain the temp. from being extreme. so if it is not there then temp will become worse and survival on earth will become impossible.

Answer 3

Naturally occurring Green House effect actually keep our planet in a stable climatic conditions i.e. it doesn't allow the heat from the eart to escape in the night time. It is just like a normal green house which has a controlled climate.

Answer 4

• The natural greenhouse effect keeps the earth warm.
• The enhanced (or accelerated) greenhouse effect is causing global warming.

NASA estimates that natural global warming (not influenced by the man-made additional warming) keeps the average surface temperature of the planet at 288oK (15oC or 59oF). Without this greenhouse effect, the average surface temperature would be 255oK (-18oC or 0oF) in effect all water on Earth would freeze, the oceans would turn into ice and life, as we know it, would not exist.

Answer 5

Two causes of greenhouse effect to be noted.

1. First is the effect from water vapour and long term effect from volcanic activity that cause ice age and recovery from the colder earth to a warmer climate naturally.
2. Second is man induced climate change, disrupting carbon cycle through use of fossil fuel and mass release of CO2 from ocean biological collapse. Human action speed up the natural process, but at what significant is still under debate due to ecological and meterological complexity.

Answer 6

The natural greenhouse effect is the way that gases in the atmosphere hold the sun's heat to keep the earth warm.

We need this for life on earth, otherwise Earth would be much colder.

(The enhanced greenhouse effect is when too much greenhouse gas is put into the atmosphere, as we are doing now. This is causing global warming.)

Answer 7

Some important greenhouse gases are water vapor, carbon dioxide, and methane.

-Water Vapor- evaporates naturally from the oceans and from land.

- Carbon dioxide is produced naturally by plants, including many plants in the ocean. It is also naturally produced by the many volcanoes and by the burning oil seepages in the Middle East and elsewhere that have naturally been on fire for centuries.

-Methane- is naturally produced by the rotting or spoiling of certain matter like horse poop or cow poop.

By the way, without greenhouse gases, the Earth would be one big iceball, so greenhouse gases are what keeps us and the plants alive.

Answer 8

There is a natural greenhouse effect caused by the amount of carbon dioxide and other greenhouse gases that have been in the atmosphere for thousands of years. These greenhouse gases capture some of the heat rising from the earth and prevent it escaping to space. This keeps the earth warm enough for life.

There is also an enhanced greenhouse effect that we are experiencing now, caused by the addition of billions of tons of extra greenhouse gas (carbon dioxide) because we have been burning fossil fuels for almost 300 years. This is not a natural process, caused by nature, but caused by us; humankind.

Answer 9

Greenhouse gases are needed to keep the planet warm. If it was not for greenhouse gases in the atmosphere, the earth would be like the moon, warm during the day and frozen at night.

Answer 10

The natural greenhouse effect keeps the earth warm enough for life. Without it we would all die.
