Greenhouse Effect Revealed

It appears that numerous changes have actually happened on the earth’s surface during the last century. The temperature across the globe rose by 1 % within a period of 100 years and this is not terrific information at all. Indeed, this refers grave issue and is supported by the fading away of ice and glaciers all around the world. It is believed that Global warming is the result of increase in the degrees of greenhouse gases in the earth’s crust mainly caused by the sun.

Sun is the major source of heat and energy for the earth. The sunlight consists of the electro-magnetic radiations that enter the earth’s surface and are absorbed by the earth. This leads to the development of infrared radiations that are emitted out into the space. The greenhouse gases like methane, carbon dioxide, trap these radiations and this outcome in the heating of the earth’s surface. The utmost result is the rise in the temperature of the earth leading to negative effects, unsafe for the existence of humanity.

And, to add to the discussion…

Green house gases have actually been in presence on earth for thousands of years. The Industrial Revolution in the 19th century caused the increase in the manufacturing of the gases. Carbons oxide, methane was released as a result of combustion of oil, gas and coal. It is the human activity that has actually been the source of the increasing the greenhouse gases in the atmosphere.

The increase in the level of greenhouse gases makes it simpler for these gases to trap the infrared radiations within the atmosphere of the earth. This has actually finally led to the radical rise in the temperature of the earth, exposing mankind to numerous threats. Polar caps, ice, glaciers and snow capped mountains are melting due to the rise in the temperature.

Going back to the times when the industrial revolution started, factories, trains, and ultimately automobiles, have burned nonrenewable fuel sources such as oil and coal, which were and still are, launching huge quantities of carbon dioxide, and other gas’s into our earths atmosphere. These green house gases, or caught heat near the surface of the earth, are formed by a natural procedure of the sun, and this is called the’ greenhouse effect’. The greenhouse effect, begins with the sun and the energy it radiates to the earth. The Earth and the atmosphere absorb some of this energy, and the rest is radiated back into space. Now with that being shared, these normally happening gases, in the atmosphere trap some of this energy and mirror it back, hence, warming the earth. Scientists now believe that the greenhouse effect is getting magnified by all the additional greenhouse gases that humans are launching.

It is clearly known that it is the human activity that has resulted in the increase of greenhouse gases in the earth’s atmosphere resulting in global warming. With little modifications in the human activities can decrease the discharges of carbon and methane. Use of natural gas, solar and wind energy can assist in curbing the emissions of carbon and methane. We will undoubtedly be able to reduce the manufacturing of greenhouse gases and lower the global warming once we regulate the carbon emission.

Discussing Greenhouse Effect

The greenhouse effect is a procedure that can be either natural or manmade. The natural greenhouse effect keeps the Earth habitable. The climate is kept relatively warm when the atmospheric greenhouse gases absorb thermal radiation from the Earth’s surface and re-radiates it in all directions.

Because one of the directions the energy is re-radiated is towards the Earth’s surface (and the lower atmosphere) the temperature on our planet is more than it would have looked like if we were only heated by solar radiation.

Although it is referred to as the greenhouse effect this natural mechanism is actually different than what goes on in a greenhouse. In that a bit of a physical structure the inside air is isolated so that heat is not lost by convection.

Broadening this discussion

However, when most people speak about the greenhouse effect they’re referring to what has become of our planet due to the manmade addition of gases to the atmosphere. These gases were released by the combustion of fossil fuels such as crude, coal, and natural gas. These additional gases have trapped a number of the aforementioned radiation that would normally have escaped from our planet. In so doing they have done our planet warmer than it would’ve been.

Greenhouse Effect; There’s Even More……

Simply put, global warming is an abnormal rise in the average near surface temperature of the planet. This ‘abnormal rise’ can be explained to several underlying factors, including pollution and deforestation, all of which amount to enhanced greenhouse effect. When the Sun’s thermal radiations are trapped by greenhouse gases within the Earth’s atmosphere, they add to the near surface temperature of the globe and cause it to rise. More lately, the concentration of these greenhouse gases in the atmosphere has risen by a significant amount. This increase in concentration of greenhouse gases, in turn, results in increase of the quantity of heat trapped within the atmosphere, and finally contributes to global warming.

It’s as if a blanket was thrown over the planet. That blanket is now keeping the upper strata of the atmosphere colder and the lower layers warmer.

Water vapor is responsible for about eighty-to ninety per cent of the natural greenhouse effect. The balance is caused primarily by carbon dioxide and methane, along with a series of minor gases.

Over the past 150 years our planet has been getting warmer. Many scientists think that this has been caused by cement being produced, the increased concentration of carbon dioxide in the atmosphere that has been the outcome of the fossil fuels being burned, and the rainforests being burned.

In 1960 the Mauna Loa observatory measured a 313 ppm concentration of carbon dioxide in the atmosphere. In 2010 it had soared almost 20% to 389 ppm. Ice core data indicate that the maximum level of carbon dioxide in the atmosphere had been fewer than 300 ppm, as a matter of reference. Over the eight hundred thousand years prior to the Industrial Revolution the level of carbon dioxide varied from 180 ppm to 270 ppm.

The fundamental factor effecting climate variations over those 800, 000 years, according to peleoclimatologists, has been the level of carbon dioxide in the Earth’s atmosphere.

Venus, the second planet from our sun, has undergone a runaway greenhouse effect. That involves water vapor and carbon dioxide. It led to the evaporation of all greenhouse gases on that planet.
