Global Warming

...

Some people say global warming is not a serious environmental threat and helpful to environment and human health. The climate fluctuates naturally all the time. It changes from day to day, month to month, season to season and year to year. At times, there is global warming; at other times there is global cooling (Singer). The greenhouse gases grow warming, but that is just minor problem. As I mentioned before that the impact of warming and the higher carbon dioxide levels are beneficial for human activities, especially for agriculture that needs carbon dioxide. “The emissions of carbon dioxide that we are putting into the atmosphere will make it more pronounced. But that doesn’t mean that the climate is going to warm perceptibly” (Singer). The global warming is a long time process. It takes long time to break off portion of ice.

However some people say global warming is a serious environmental threat. Also it is harmful to environment and human health. “The greenhouse effect is a natural phenomenon involving the interaction of the sun’s energy with atmospheric gases” (Gelbspan). Somehow the human activities also produce greenhouse gases. The activities are the combustion of fossil fuels, landfills, dry cleaning, chemical production, aluminum smelting, etc. “When rainforests are burned, or the trees are cut and left to decay, the carbon is released into the atmosphere as carbon dioxide. This is the second largest factor contributing to the greenhouse effect” (Gelbspan). Rain forests are referred to carbon sinks because they absorb carbon from atmosphere and keep atmospheric temperature from rising. “The IPCC estimates that, by 2100, the atmosphere will warm between 1 and 3.5 degrees Celsius. But even a slight increase could have a tremendous impact” (Gelbspan).

In conclusion, from research on global warming, I think the good of global warming are heavier and more supportive than bad of global warming. Still I think we should slow the process not to stop. It is helpful to many countries and human in health. So we should not worry about global warming and lose our sleep.
