Global warming is one of the most serious challenges facing us today. Global warming is basically the increase in the temperatures of the Earth's atmosphere, land masses and oceans. The Earth's surface temperature is at an average of 59F and over the last hundred years, this figure has risen to about 1F. By the year 2100, the average change in the temperature of the Earth could range from 2.5F to about 10F, enough to melt glaciers and polar ice caps.
The cause of global warming Global warming has and will always occur naturally.it has become such a concern in our lifetime is due to the fact that human activities and practices have contributed significantly to its occurrence and severity. Tropical deforestation is the largest source of emissions for many developing countries, but slowing deforestation can't solve the climate problem by itself.Other human practices that contribute to global warming is the agricultural revolution has also contributed to global warming. As more and more communities need lands converted from forests to residential and commercial areas, biomass is reduced, contributing to the increase in the presence of carbon dioxide in those regions. Since carbon dioxide is processed by plants and trees, their absence contributes to its increase.
It is estimated that about 25% of the annual increase in the carbon dioxide found in the Earth's atmosphere is caused by extreme changes and usage of the Earth's natural resources. Other practices also include deforestation, salinization, desertification and overgrazing also contribute to global warming. The causes of global warming are over emission of carbon dioxide (Co2) and deforestation. The effect are clime changed,more heat waves that increase heat-related illnesses and death, more frequent flooding , long drought, the coast area more vulnerable to coastal storm,the farmers & sailor lose their income source, and irretrievably changed in wetlands.
Facing the facts of global warming Countries all over the world have just begun to acknowledge the negative effects of global warming not only to the world's politics and economy but also to humankind in general. Many of the world's governments have encouraged implementation of measures to try to counteract the problem of global warming through careful measures and practices designed to protect and respect the environment.
Global warming is the world problem that must be solve. The solutions of this problems are decrease emissions of carbon dioxide (C02), use the fuel-efficient vehicles, renewable energy, protecting threateded forest. Expecially for business and goverment ,they should take the best way to make them (above) available and affordable, and as consumers must know what to do and give opinion to make better choices to solve this problem.
