Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades and its projected continuation. An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados. Other consequences include higher or lower agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors. I think that Global Warming is bad. And we have to do anything, but we poor mortals, aren´t have sufficient power. So, we have to do minium thing, such as, avoid CFC´s, walk by foot. And you? What do you think about it? What do you do?
