The greenhouse effect regularly gets an unfavorable impression as a result of its relationship with a global warming, but as a matter of fact we couldn't live without it.
The greenhouse effect is a natural process that warms the Earth’s surface.If it were not for greenhouse gases trapping heat in the atmosphere, the Earth would be an exceptionally cool place. These greenhouse gases keep the Earth warm through a process known as the greenhouse effect.
Life on earth depends on energy from the sun in the form of sunlight.When the Sun’s energy reaches the Earth’s atmosphere, about 30 percent of the sunlight that beams toward Earth is deflected by the outer atmosphere and scattered back into space.The rest reaches the planet's surface, absorbs some of this energy and heats up. That is the reason the surface of a road can feel hot even after the sun has gone down because it has absorbed a considerable amount of energy from the sun. Aside from absorbing by earth's surface it is also reflected upward again as a type of slow-moving energy called infrared radiation and re-radiated by greenhouse gases Meaning the heat caused by infrared radiation is absorbed by "greenhouse gases" such as water vapor, carbon dioxide, ozone, nitrous oxide, methane and some artificial chemicals such as chlorofluorocarbons which slows its escape from the atmosphere.
The absorbed energy warms the atmosphere. As the air gets warmer, it makes the Earth's surface warmer,also. They regulate our climate by trapping heat and holding it in a kind of warm-air blanket that surrounds the planet.This process maintains the Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth. This extraordinary phenomenon is what scientists call the "greenhouse effect." Without it, scientists assess that the normal temperature on Earth would be colder by more or less 30 degrees Celsius (54 degrees Fahrenheit),unreasonably cool to sustain our current ecosystem.
While the greenhouse effect is an essential environmental prerequisite for life on Earth to exists, truly this can be excessively of something worth being thankful for.The issues begin when human activities misshape and accelerate the natural process by increasing or creating more greenhouse gases in the atmosphere than the necessary amount to warm the planet to an ideal temperature. These human activities are:
1.Burning natural coal, oil and gas including gasoline for automobile engines raises the level of carbon dioxide in the atmosphere.
2.Some land-use and farming practices changes increase the levels of nitrous oxide and methane.
3.Many factories create long-lasting mechanical or industrial gases that do not occur naturally, yet help significantly to the enhancement of greenhouse effect and global warming that is presently under way.
4.Deforestationis another factor, Trees use carbon dioxide and give off oxygen in its place to help balance the gases in the environment. As more woodland forests are cut down to make way for farming or logged for timber, the fewer trees to perform a critical function of creating the optimal balance of gases in the atmosphere.
5.Population growth also contributes in global warming, on the grounds that if more individuals use fossil fuels for transportation, manufacturing and heat, the level of greenhouse gases continues to increase. As more factories and farming occurs to feed millions of new people, the more greenhouse gases enter the atmosphere.
More greenhouse gases implies more infrared radiation trapped and held, which gradually increases the temperature of the Earth's surface and the air in the lower atmosphere.
While the majority of mainstream scientists agree that global warming is a serious problem that is growing steadily worse, there are others who disagree. Arguing that global warming isn't worth worrying about.They reached this opinion after analyzing millions of measurements from weather satellites in an effort to find a global temperature trend. They found no sign of global warming in the satellite information data, and now accepts that forecasts of global warming by as much as 10 degrees Fahrenheit by the end of the 21st century are incorrect or erroneous.
Some scientists agree that even a small increase in the global temperature would prompt to significant weather and climate changes:
. Affecting cloud cover,the recurrence and severity of storms, wind patterns, precipitation and the seasons duration.
.Rising temperatures would raise sea levels as well, diminishing supplies of fresh water as flooding happens along coastlines worldwide and salt water reaches inland.
.Many of the world’s endangered species would become extinct as rising temperatures changed their habitat.
.A large number of individuals likewise would be affected, particularly poor people who live in dubious areas or depend on the land for a subsistence living.
.Certain vector-borne diseases carried by insects or animals such as malaria, would become more prevalent as warmer conditions expanded their extent.
Today, the increase in the Earth's temperature is expanding with unprecedented rate. To see exactly just how rapidly global warming is accelerating, consider this findings. During the entire 20th century, the normal worldwide temperature increased by about 0.6 degrees Celsius ( more than 1 degree Fahrenheit).Using computer atmosphere models,researchers predicted that by the year 2100 the average global temperature will rise by 1.4 degrees to 5.8 degrees Celsius ( 2.5 degrees to 10.5 degrees Fahrenheit).
Currently, carbon dioxide accounts for more than 60 percent of the enhanced greenhouse effect caused by the increasing level of carbon dioxide in the air which is increasing by more than 10 percent every 20 years. If emissions of carbon dioxide keep on growwing at current rates, then the level of the gas in the air will probably double, or possibly even triple, from pre-industrial levels during the 21st century.
According to the United Nations, some atmospheric change is already unavoidable because of emissions that have happened since the beginning of the Industrial Age.While the Earth’s climate does not react quickly to outside changes, many scientists believe that global warming already has critical momentum because of 150 years of industrialization in numerous nations around the world. And global warming will continue to affect life on Earth for hundreds of years, even if the increase of greenhouse gas emissions in atmospheric levels halted or greenhouse gas emissions are reduced.
To lessen those long-term effects, many countries, communities and individuals are taking action now to reduce greenhouse gas emissions and slow global warming by expanding the use of renewable energy, decreasing reliance on fossil fuels, expanding the forests, and making lifestyle choices that help to sustain the environment.
As whether they will have the capacity to select enough individuals to go along with them, and whether their combined efforts will be enough to head off the most serious effects of global warming, are open questions that can only be answered by future developments.
