The more greenhouse gases there are the less heat flows out of the Earth's atmosphere. The less greenhouse gases there are the more heat flows out of the Earth's atmosphere.
Greenhouse gases rarely flow into the earth's atmosphere

Sunlight hits the earth and warms it. Carbon dioxide receives this heat and reflects (re-radiates) it back down warming more earth. In effect, carbon dioxide traps the heat, keeping it on the earth and warming it more.
36 million years ago carbon dioxide levels were 400 parts per million. At 400 part per million the earth was very warm and there were trees growing on Greenland. For the next 36 million years carbon dioxide level were falling at a very slow rate until 1850. In 1850 there were 280 parts per million of carbon dioxide in our atmosphere and the planet was at its coolest point in 36 million years. In 1850 the industrial age started and factories began to pour out carbon dioxide laden smoke. The earth began to warm. Now we have about 380 parts per million of carbon dioxide. The earth is warmer than it was a hundred years ago. We are getting close to 400 parts per million when there was no ice on any glacier and the sea was at its highest level.
Methane is another greenhouse gas, but is 20 times stronger in trapping heat. It is estimated that methane hydrates are on the order of 1 to 2 million trillion cubic feet and it is just under our feet and not in the atmosphere. This methane is stable when very cold or under pressure. This methane can be trapped under ice caps, permafrost, and cold lakes. Warming water can release this methane and it will bubble to the surface. Also, thawing permafrost allows the dead plants trapped in the frozen ground to decompose and make more methane. The combination of carbon dioxide and methane will accelerate the temperature rise here on earth. Currently, methane gas is bubbling up in lakes from Siberia to Alaska. Even Mono Lake in California is releasing methane.
They make it warmer.
They slow the loss of heat

The greenhouse effect warms the gases in the atmosphere.
They stop heat from escaping the atmosphere.

greenhouse effect
Greenhouse gases affect the temperature of the atmosphere. They capture the sun's heat and warm the planet.
The greenhouse effect warms the gases in the atmosphere.
They stop heat from escaping the atmosphere.
Of course, greenhouse gases keep the Earth from being one large popsicle. The newest studies of the atmosphere indicate that the atmosphere is pretty stable, now. The reason is that nearly all of the greenhouse gases are water vapor mostly evaporated from the oceans.
How are atmospheric gases like the glass in a greenhouse
The greenhouse effect is caused by greenhouse gases that absorb infrared rays and thereby keep the earth warmer than it otherwise would be. The greenhouse effect is important to life on earth. Without greenhouse gases, there would be global cooling and life as we know it would no longer be possible. With increased levels of greenhouse gases, there is global warming and undesirable climate change.
The greenhouse effect (greenhouse gases capture heat radiating up from the earth).
it allows solar radiation to penetrate to the surface!
Greenhouse gases absorb heat rising from the suface of the earth. The more greenhouse gases there are, the more heat is absorbed. This is what is happening now. By burning fossil fuels (coal, oil and natural gas), we are adding extra carbon dioxide to the atmosphere and this is causing global warming.
