Advanced An enhanced greenhouse effect from CO2 has been confirmed by multiple lines of empirical evidence. Satellite measurements of infrared spectra over the past 40 years observe less energy escaping to space at the wavelengths associated with CO2. Surface measurements find more downward infrared radiation warming the planet's surface.

The incoming radiation is short wave ultraviolet and visible radiation. Some of the radiation will be absorbed by the atmosphere and some of it will be reflected back from the earths surface into space.
The radiation that is reflected back into space is infrared radiation which has a longer wavelength.
Green house gases such as carbon dioxide, methane, and oxides of nitrogen tend to absorb some of the reflected infrared radiation and re-reflect it back towards the earth.
This is what causes the greenhouse effect and it results in an increase in average mean temperature on earth. It is a natural phenomenon. However, since there has been an increase in the green house gases in the past century, this has resulted in an increase of the green house effect leading to higher than normal average temperatures which could lead to disastrous consequences in the future.
The incoming radiation from the sun is short wave ultraviolet and visible radiation.
Some of this radiation is absorbed by the earths atmosphere. Some of the radiation is reflected back into space by the earths surface.
The radiation which is reflected back into space is infrared radiation and has a longer wavelength. The greenhouse gases in the atmosphere absorbe some of this infrared radiation and re-reflect it back towards the earth. This causes the green house effect and results in an increase in average mean temperatures on earth.
A rise in greenhouse gases results in an increase of the green house effect which can be disastrous for the planet. The precautionary principle holds that, if the effects of a human-induced change would be very large, perhaps catastrophic, those responsible for the change must prove that it will not do harm before proceeding.
This is the reverse of the normal situation, where those who are concerned about the change would have to prove that it will do harm in order to prevent such changes going ahead. There is strong evidence that shows that green house gases are causing global warming.
This is very worrying as global warming has so many consequences on ecosystems. If nothing is done, and the green house gases are in fact causing the enhanced green house effect, by the time we realize it, it will probably be too late and result in catastrophic consequences.
So even though there is no proof for global warming, the strong evidence suggesting that it is linked with an increase in green house gases is something we can not ignore.
Global warming is a global problem. For these reasons, the precautionary principle should be followed. Anyone supporting the notion that we can continue to emit same amounts or more of the green house gases should have to provide evidence that it will not cause a damaging increase in the green house effect.
Global warming could have a number of disastrous consequences largely affecting the arctic ecosystems:THE ENHANCED GREENHOUSE EFFECT AND GLOBAL WARMING WHAT IS CLIMATE?
Climate and weather are not the same thing. Both describe conditions in the lower atmosphere — for example, wet or dry, cold or warm, stormy or fair, and cloudy or clear.
Weather is the short-term local state of .
Before we can decide whether the impact of the greenhouse effect is beneficial or harmful, it is important to learn what it is and why the greenhouse effect is important. What is a greenhouse? A greenhouse is an air-tight glass building that is used extensively by commercial plant growers, gardeners and botanists to grow plants which otherwise. Thank you for your interest in this topic.

The International Journal of Greenhouse Gas Control is a peer reviewed journal focusing on scientific and engineering developments in greenhouse gas control through capture and storage at large stationary emitters in the power sector and in other major resource, manufacturing and production industries.
The Journal covers all greenhouse . Introduction.
Humans are now the main cause of changes of Earth’s atmospheric composition and thus the drive for future climate yunusemremert.com principal climate forcing, defined as an imposed change of planetary energy balance –, is increasing carbon dioxide (CO 2) from fossil fuel emissions, much of which will remain in the atmosphere for .
A Bayesian Statistical Analysis of the Enhanced Greenhouse Effect As such, the enhanced greenhouse effect is a plausible explanation for the observed global warming. Long term natural variability is another prime candidate for explaining the temperature rise of the last century.
