Scientists have know for more than a century that carbon dioxide and other “green house gases” (including water vapor, methane, and cholorfluorocartons) help prevent heat from escaping the earth’s atmosphere.
In fact, it is this “green house” effect that keeps the earth warm enough to support life. Yet there can be too much of a good thing. Ever since the dawn of the industrial age, humans have been burning large quantities of fossil fuels, releasing the carbon they contain as carbon dioxide. Because of this, some has estimated that by the year 2050, the amount of carbon dioxide in the air will be double what is was in 1850. By 1982 an increase was apparent. Less than a decade later, many researchers were saying that the climate had already begun to warm.
Some of us, or the majority of us may not have been aware of this, for tiny things seem to be correlated with our daily life, while, the tiny make the changes.
