The Earth's average temperature has been increasing for a long time. At this day and age, the temperature increases about three degrees farenheit per century. Although it's warming everywhere, it isn't warming at the same rate everywhere. For inastance, the temperate deciduous forest areas happen to have the quicker increasing temperatures. The effect of the warming situation changes water circulation and winter and nighttime temperatures more than summe and daytime temperatures. Global warming is natural, but the quick increases is mainly from humans. When humans release gases into the air, like greenhouse gases, the gases collect radiation. Carbon dioxide is another contributer from humans. As the carbon dioxide within the air increases, so do the plants. The warm temperatures even extend the growing season, and also make water evaporate faster. When water evaporates faster, there are more rain clouds, which means more percipitation. More percipitation is equal to more acid percipitation which hurts the plants in the deciduous forest (Allaby 1, 220-224).
