PIDATO GLOBAL WARMING

Good morning ladies and gentleman,

First of all I would like to say thanks to God because today, I can stand here to bring my oration about the impact of the global warming.

We know global warming is serious problem which is world well in country developing and country developed. Global warming in reason by activity human which working way a ware or not a ware.
Do you know, global warming is a process to increase body temperature average atmosphere: sea and earth continent. Stage body temperature global settlement will to cause alteration which other except to climb surface sea water, stage weather, and alteration total. Result global warming which other influenced crop agriculture, and destroyed kind animal. All energy source which can be ground originally with sun.
A part that energy inside form short wave radiation, including apparent shine when this energy to hit ground surface it changeable with shine to make hot with to warm up earth.
With temperature average large 15 C (59F), earth in fact already hot more 33 C (87F) with greenhouse effect. So that ice will to shut all ground surface but on the contrary. Result total that gas already more in atmosphere global warming result to become.
To protect the health and economic well-being of current and future generations, we must reduce our emissions of heat-trapping gases by using the technology, know-how, and practical solutions already at our disposal.
The Earth’s climate changes in response to external forcing, including variations in its orbit around the Sun (orbital forcing), volcanic eruptions, and atmospheric greenhouse gas concentrations. The detailed causes of the recent warming remain an active field of research, but the scientific consensus is that the increase in atmospheric greenhouse gases due to human activity caused most of the warming observed since the start of the industrial era. This attribution is clearest for the most recent 50 years, for which the most detailed data are available. Some other hypotheses departing from the consensus view have been suggested to explain most of the temperature increase. One such hypothesis proposes that warming may be the result of variations in solar activity.

None of the effects of forcing are instantaneous. The thermal inertia of the Earth’s oceans and slow responses of other indirect effects mean that the Earth’s current climate is not in equilibrium with the forcing imposed. Climate commitment studies indicate that even if greenhouse gases were stabilized at 2000 levels, a further warming of about 0.5 °C (0.9 °F) would still occur.

Ladies and gentleman,
The impact that can generated by the global warming are:
1. Climate Start Unstable.
All scientist estimate that during global warming, upstate area of North hemisphere will be hot more than other areas under the sun. As a result, ices mounts will melt and continent will minimize. Will be more a little adrift ice in territorial water of North. previous areas experience of light snow, might not will experience of the snow again. To mountain in subtropical area, snow-covered shares will progressively a few/little and also will be more quickly melt. Season plant will be more be long in some area. Temperature at nighttime and winter will tend to mount.
Warm area will become damper because more water which condensing from ocean. All scientist not yet so sure do the dampness also will improve or degrade further warm-up again. This matter is caused by aqueous represent glasshouse gas, so that its existence will improve polythene effect at atmosphere. However, aqueous v which is more also will form cloud which is more, so that will bounce sunlight return to outer space, where this matter will degrade warm-up process. high dampness will improve rainfall, meanly, about 1 % to each warm-up degree Fahrenheit.. Storm will become a more regular. Besides, water will be more quickly condense from land. As a result some area will become is drier than previously. Wind will blown faster and possible with different pattern. hurricane obtaining its strength from evaporation of water, will become bigger. At variance with warm-up that happened, some period which is very chilled possibly will happened. Weather pattern becoming not approximating and more extreme.
2. increase the global temperature.

People possible of opinion that warm Earth will yield the more food from previously, but this unequal matter in fact in some place. Part of Canadian South, for example, possibly will get advantage from is higher of rainfall him and is longer [of] him a period of planting. On the other hand, semi tropical agriculture farm run dry in African some part might not earn to grow. Area agriculture of desert using irrigation water of mounts which far can suffer if snow pack ( snow corps) wintry, functioning as natural reservoir, will melt before months top a period of planting. Food crop and forest can experience of insect attack and more super disease.


3. the trouble of ecology.

Animal and plant become difficult mortal duck out this warm-up effect because most farm have been mastered by human being. In global warm-up, animal tend to have migration up at pole or to of mountain. Plant will chop round its growth, searching new area because habitat of[is the duration becoming too warm. However, development of human being will hinder this transfer. Species which is have migration to north or south hindered by agriculture farms or towns possibly will die. Some species type which unable to quickly make a move to go to pole possible also will be annihilate.


Ladies and gentleman,

the way to prevent the global warming is,

1. eliminating carbon.

Way of easiest to eliminate dioxide carbon on the air is by looking after grove and plant tree more amount of. Tree, young especially and quickly its growth, permeating very dioxide carbon breaking, many to through photosynthesis, and carbon save in its wood. In all the world, mount of forest have reached level feeling concerned about. In many area, crop which grow again pittance because land losing of its fertility when altered for other usefulness, like for the farm of agriculture or development of house remain. Step to overcome this matter is with reboisation which play a part in to lessen progressively increasing greenhouse gas .

Carbon dioxide gas also can be eliminated directly. Its way by inseminating to oil wells to push petroleum to go out to surface. Hypodermic also can be conducted for the insulation of this subterranean gas like in oil well, coal coat or of aquifer. This matter have been conducted in one of the offshore drilling bridge of Norwegian, where brought dioxide carbon to surface with natural gas arrested and hypodermic return to aquifer so that cannot return to surface.

I think that’s all which I give to you, Thank you.
