Greenhouse gasses harm the Earth because they pollute the air and makes our atmosphere thinner. When that happens, it is letting more and more heat in our Earth that drought will happen and water will be lost.

How do greenhouse gases affect the earths atmosphere?
They slow the loss of heat
Why do greenhouse gases warm the atmosphere but other gases do not?
Greenhouse gases don't "warm the atmosphere". What they do is trap heat.Why is because that's the definition of "greenhouse gas". Okay, a little more detail: they're transparent to high frequency radiation (visible light and UV) but largely opaque to lower frequency radiation (like IR). So energy in the form of visible light gets to the surface just fine, but when it's time to reradiate it as heat, greenhouse gases block the emission of the lower frequency IR "heat" radiation.
Why do you need greenhouses?
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.
What do gases affect?
Greenhouse gases affect the temperature of the atmosphere. They capture the sun's heat and warm the planet.
What causes earth surface to get warm?
Sunlight. The warmth rises into the atmosphere where some is trapped by greenhouse gases. These warm gases then warm the earth's surface again.
What is earth's lower atmosphere is kept warm by?
gases
Why is it incorrect to say that greenhouse gases cause global warming?
It is not incorrect, Greenhouse gases are Methane and Carbon Dioxide and their increasing presence in Earth's atmosphere is causing the temperature of the atmosphere to rize (warm).
What two things keep your atmosphere warm?
The natural greenhouse effect, helped by greenhouse gases and the carbon and water cycles of the earth keep the atmosphere warm. Greenhouse gases keep back some of the sun's heat so it doesn't radiate back out to space. This has kept the earth warm for millions of years.
Why does the greenhouse effect cause warmer temperatures near the surface of earth?
The greenhouse gases are in the troposphere, that's the lowest layer of the atmosphere. The sun's rays come in and warm the earth. The warm earth then radiates infrared heat, some of which is trapped by greenhouse gases in the lower atmosphere. These greenhouse gases (water vapor, carbon dioxide, methane, nitrous oxide and CFCs) warm up. They in turn radiate their warmth and some of it goes down again and warms the earth's surface. The heat can continue going up and down like that.
What are the functions and actions of greenhouse gases?
To trap heat. The functions of greenhouse gases are to absorb heat from sunlight and trap it in the atmosphere to warm the Earth and melt the ice caps.
How does the greenhouse effect affect the air temperature?
The greenhouse effect keeps the air and earth warm enough for life.The sun's energy warms the earth.Infrared heat rises from the surface of the earth into the atmosphere where it is trapped by greenhouse gases causing the greenhouse effect.The warm greenhouse gases in turn warm the surrounding atmosphere, and some of this heat goes back down to earth, where it adds more warmth to the earth's surface.
What happens to greenhouse gases at natural levels in the atmosphere?
At natural levels of greenhouse gases in the atmosphere (before the Industrial Revolution), the carbon cycle moved carbon dioxide in and out of land, sea and air. Enough carbon dioxide remained in the atmosphere to keep the earth comfortably warm, warm enough for life.
