Origins of global warming - Essay Example

These trapped gases are called greenhouse gases. The human activities create carbon dioxide CO2 which is a type of a greenhouse gas that slows the escape of heat from the earth. Trees and plants contribute a lot in removing these gases from the environment through photosynthesis. However, due to illegal logging and other similar activities, there are only fewer trees and plants today. Aside from human activities, it is also proven that natural processes also cause global warming. These processes include the increase of energy given off by the sun due to depletion of the ozone layer.

The effects of this phenomena is resulting in to animals change of habitats, impairment of ocean life, weather damage, rising sea level, changes in crop yield, and threats to human health. Extensive alteration of temperature among habitats causes animals less possibility to adapt with the environment. Warmer waters increase the stress and spread diseases on the marine ecosystem. Global warming causes a large amount of ice to melt and leads to higher sea level. Many crop plants can not tolerate higher temperature and eventually die.

Lastly, tropical diseases among human beings such as malaria and dengue are more visible to larger regions. Intense heat waves, drought and floods increase number of people die due to hunger, malnutrition, heat stroke and other illnesses. The great impacts of global warming are not only observable to human beings but also to the entire ecosystem. It is irrevocable that in any issue, there are skeptics. Despite the fact that effects of global warming are highly noticeable, disbelievers still arise even from the group of scientists.

In fact, an atmospheric physicist Fred Singer said that "The observational evidencesuggests that any warming from the growth of greenhouse gases is likely to be minor, difficult to detect above the natural fluctuations of the climate, and therefore inconsequential". Giving less importance to the issue leads to resistance of resolving it. Probably, it is one of the reasons why in spite of vocal suggestions concerning avoidance of harmful human activities, it is near impossible to reduce the effects of global warming.

Given this fact, it is absolutely necessary to settle this disbelief even before the misperception continues to spread. Green leaders, on the other hand, stand to their stance that current changes in the ecosystem are triggered by something and this is global warming. The U.S. National Academy of Sciences declared in 2005 that "greenhouse gases are accumulating in Earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise," adding that "the scientific understanding of climate change is now sufficiently clear to justify nations taking prompt action.

" Amongst these two counter-arguments, how is it possible to create one's' own stand There is no absolute answer for this. However, put in mind that if people will act in accordance with the green leaders, no one can be harm. If people choose to take global warming for granted which turn out to be fact, thus, life of everyone even those innocent creatures is at high risk. The future depends on a well-thought decision. This explains half of what's' global warming is about. There is lot of details to research before it is fully defined.

However, the basic knowledge of its causes and effects is
