Though the ‘greenhouse effect’ does contribute to the regulation of heat and warmth on our planet, it sometimes tends to have a bad reputation as the root of global warming. The survival of human beings, along with other organisms like plants and animals on the earth, is contingent on the energy and warmth that we get from the sun.
Let us understand what greenhouse effect is all about. The main source of light and natural energy to earth is sun. Almost half of the suns energy in rays is absorbed by earths surface. Earth in return, radiates back this energy in form of infrared rays. Now, when this heat is absorbed by greenhouse gases like carbon dioxide, methane, nitric oxide and gets trapped, it results in global warming.
There’s Always More About Greenhouse Effect…
It is hypothesized that approximately thirty per cent of the sunlight that is beamed onto the planet is actually reflected back by our surrounding atmosphere. The rest of the heat is able to reach the face of the planet, but is also reflected back upward slowly and called infrared radiation.
Life on earth depends on energy from the sun. About 30 percent of the sunshine that beams toward Earth is deflected by the outer atmosphere and scattered back into space. The rest reaches the planet’s surface and is reflected upward again as a sort of slow-moving energy called infrared radiation. The heat caused by infrared radiation is absorbed by ‘greenhouse gases’ such as water vapor, carbon dioxide, ozone and methane. This slows its escape from the atmosphere.
Greenhouse gases absorb the heat that is created; these gases include water vapor, ozone, carbon dioxide, and methane. Though the ‘greenhouse’ substances don’t make up very large proportion of the atmosphere, there are the most important way that heat is retained; they serve as a blanket for the earth and trap heat caused by infrared radiation to warm the atmosphere.
Global warming caused by the effect of the Glass House event the face of the earth to absorb some heat and toss the rest back. Some of this heat as infra red radiation wave length to outer space. But some remain trapped heat in the atmosphere accumulate earth due to the quantity of greenhouse gases include carbon dioxide, water vapor, and methane the wave radiation into this trap.
Without this process, we wouldn’t be able to sustain life on Earth; scientists have hypothesized that the temperature of our planet would be at least thirty degrees Celsius less than it is now. Though this process is vital to the survival of human beings and the ecosystems, there’s such a thing as too much warmth.
At the present time, the mean temperature on the earth is plus 15 degrees Celsius. Without the greenhouse effect, the mean temperature would also be around 15 degrees, but it’d be with the other symbol, that is to say, minus 15 degrees Celsius.
Unfortunately, human being’s activities have an effect on the atmosphere and disturb the process and natural equilibrium of the greenhouse gases that warm the earth. This is done by all different measures, including the combustion of fossil fuels, producing industrial toxins and releasing them into the air, land use changes, population growth, and deforestation.
However the earth’s climate has changed many times in the planet’s history, with events ranging from ice ages to long periods of warmth; the current industrial development and human activities has accelerated the climate change and worsened the damage caused to the environment. Human activities are changing the natural greenhouse effect, on Earth. Many human activities are responsible for releasing much more greenhouse gases than the earth can possibly sustain. Over the last century the use of fossil fuels like coal and oil has increased the concentration of atmospheric CO2. This happens because the coal or oil burning process combines carbon (C) with oxygen (O2) in the air to make CO2. Atmospheric CO2 has increased about 25 percent since the beginning of the 1 800s.
The more greenhouse type substances that are emitted into the air, the more infrared radiation is trapped and held in. This can gradually increase the overall temperature of the planet.
Scientists have suspected that the warmth of the Earth is actually increasing much faster than they ever expected it to.
However, there are likewise many that feel like global warming isn’t worth worrying about and that it won’t have a high enough effect on the planet. Some argue that there’s even signs that it’s a problem.
Researchers have been studying this by all different methods, including examining satellite readings of temperatures throughout the world and measuring sea levels and the thawing of the ice caps at the poles.
Though there is a divide between most intellectual thinkers and their views on global warming, they’re able to agree that even a small increase in the overall temperature of the planet could cause a great deal of changes, including some that may threaten life on Earth. Some of these include cloud cover, precipitation levels, weather changes, patterns of wind, storm severity and frequency, and how long the seasons last/how intense the changes are.
It is suggested that much of the world’s endangered species would be killed off or become extinct as a result of the changes to their habitats. The sea levels may also rise, reducing fresh water supplies.
Carbon dioxide emissions are mostly to blame for the changes in the Earth’s atmosphere. When fossil fuels are burned, they release a series of different gases into the air, but the key element is carbon dioxide.
This changes the makeup of the air and how we’re able to survive and live. Vehicles are mostly to blame for the large number of this substance in the air, so there’s been a recent push to make automobiles more energy efficient.
This can be achieved through the using of electricity to power them, whether it is derived from solar cells and solar panels or generators that have been powered by other methods of alternative energy. Though not everyone agrees that global warming is a threat, most scientists do feel that we ought to change the ways that we get and use energy, at least for the improvement of the Earth and its future.
Climate changes themselves are inevitable, particularly as the population of the world changes. However, ones that are too drastic will definitely change our ways of life and our abilities to survive.
Many nations have begun an attempt to reduce their carbon footprint and to be more energy efficient by finding alternative forms of energy, as well as recycling, planting forests, and changing their lifestyles so that they are able to live more ‘green. ‘ The future of the atmosphere is uncertain. However, we can do our best now to prevent permanent damage.
