They do. Greenhouse gases in the atmosphere retain heat rising from the surface of the earth and stop it escaping into space. This keeps the earth comfortably warm and has done for thousands of years.
Greenhouse gases have been working with the heat from the sun to keep the earth comfortably warm for millions of years. The gases absorb some of the heat from the warmed earth and keep it from escaping into space. When greenhouse gas levels increase, as they are from recent human activity, they retain more heat and the earth warms up.
The earth's overall temperature with greenhouse gases is 76442 degrees F.
The greenhouse effect is the way certain gases in the atmosphere trap heat rising from the surface of the earth. This warming keeps the earth comfortably warm enough for life. Since the Industrial Revolution, 200 years ago, we have been adding extra gases which are now producing an enhanced (or accelerated) greenhouse effect which is causing global warming.
Greenhouse gases keep the earth warm.Too much greenhouse gas is causing global warming.
If it weren't for the Greenhouse Effect, the Earth would be very cold. But it is only good to a certain point. We humans are throwing high levels of greenhouse gases into the air that is causing what we have labeled Global Warming.
They slow the loss of heat
Yes, greenhouse gases trap heat in the troposphere, which is the lowest layer of the earth's atmosphere.
Yes, greenhouse gases are part of the natural greenhouse effect. The gases absorb the heat coming off the surface of the earth and become warm. This warming has kept the earth warm enough for life for millions of years.
Greenhouse gases are helpful because they keep the earth warm enough for life. Too much greenhouse gases warm the earth up too much.
If there were no greenhouse gases the earth could not support life. Greenhouse gases are naturally occurring and allow heat to be retained within the atmosphere.
Water vapor, carbon dioxide, methane, ozone and nitrous oxide. They are known as 'greenhouse gases'.
