Are greehouse gasses good or bad?

Answer 1

Yes and no.

We need greenhouse gases in our atmosphere to keep the earth warm enough for human life. So the right level of greenhouse gas is good.

Too much greenhouse gases are bad for us. Carbon dioxide, methane, nitrous oxide and fluoridated gases are the gases which trap sunlight and heat from the surface of the earth and so they are used by the greenhouse effect to heat the atmosphere. This leads to overheating in the atmosphere which in turn leads to global warming.

Answer 2

Green house gases, like carbon dioxide and methane, are good in moderation. They act like a blanket, keeping the Earth warm and keeping it from going into the next ice age. However, when there are too many green house gases in the atmosphere we have problems like global warming.

Answer 3

The amount of greenhouse gases in the air before we began burning fossil fuels (coal, oil and natural gas) was just right for keeping the earth comfortably warm enough for life.

Since the Industrial Revolution, when we discovered that burning coal would power a steam engine, we have been adding more and more greenhouse gases to the atmosphere. This is causing global warming, which is not good for the earth.

Another Perspective:One must consider that what is good for the Earth, may not be what is good for humans, and vice versa. The Earth, after all, has been here far longer than humans, and is likely to be here long after humans are an historical footnote.

For the record, the primary greenhouse gasses are carbon based: chlorofluorocarbons, carbon monoxide, carbon dioxide, etc.; and, those other gases that reflect thermal energy: water vapor, methane, nitrous oxide, and ozone The current level of carbon in the Earth's is around 391 ppm. One of the highest levels of carbon in the Earth's atmosphere is roughly ten times that amount, at 3,950 ppm. That existed about 56 million years ago, during the transition from the Paleocene and Eocene epochs. The average temperature at the poles during this time was 55 to 68 °F.

Oh! And the human infestation wasn't to occur until over 55 million years later. One has to wonder what caused that explosion of atmospheric carbon before all those nasty humans started burning coal and oil.

Answer 4

Greenhouses are bad because that they start global warming.

Answer 5

All greenhouse gases are good for eartj but when the ratio of greenhouse gases increases then they will all be dangourus for the earth
