The average surface temperature of Earth is maintained by a balance of various forms of solar and terrestrial radiation. Fourier, however, neither used the term greenhouse effect nor credited atmospheric gases with keeping Earth warm.
Without this atmospheric condition, life on Earth would be vastly different, or even nonexistent. This trapped energy heats up the atmosphere, increasing the temperature of the planet and distributing warmth to its night side, when solar heating is unavailable.
The denser the atmosphere, and the higher the concentration of energy-holding molecules like water vapor and carbon dioxide, the more energy the atmosphere can trap. Positive Effects The greenhouse effect is important, because it contributes to the survival of life on Earth.
Without the greenhouse effect, the temperature of the planet would be similar to conditions experienced on the moon.
On the lunar surface, with no atmosphere to mediate temperature swings, the surface can reach degrees Celsius degrees Fahrenheit during the day and degrees Celsius degrees Fahrenheit at night.
This dramatic temperature change required NASA to develop specialized gear to protect astronauts from both extremes for the moon landings. A similar temperature swing on Earth would have produced an environment hostile to most living things. Sciencing Video Vault Too Much of a Good Thing Unfortunately, while a moderate greenhouse effect is vital to life, an elevated greenhouse effect can be dangerous.
Since the Industrial Revolution, the widespread adoption of fossil fuels has increased the amount of carbon dioxide, water vapor, and other greenhouse gases in the atmosphere.
Climate scientists point to this increase in heat-trapping gases as one of the reasons global temperatures have risen during this period. Extreme Effects One of the chief concerns about an increase in the greenhouse effect is that the changes can become self-sustaining.
As more greenhouse gases enter the atmosphere, its ability to trap heat increases. As the warmth of the atmosphere increases, the amount of water vapor it can hold increases as well, further boosting the effect. In addition, increased global temperatures threaten to release large amounts of carbon that is currently frozen into permafrost zones, also exacerbating the problem.
Excessive heat retention could lead to massive changes in natural water distribution and available land mass on a global scale.
