The climate of the earth is always changing. In the past it has changed through 14burninggreenhouseindustrial revolutionnaturalrainfallrisingsunvolcanic causes, such as 14burninggreenhouseindustrial revolutionnaturalrainfallrisingsunvolcanic eruptions and the activities of the 14burninggreenhouseindustrial revolutionnaturalrainfallrisingsunvolcanic. We are currently in a warm period but since the 1850's the temperature has been 14burninggreenhouseindustrial revolutionnaturalrainfallrisingsunvolcanic far more than it should do naturally. The 1850's saw the beginning of the 14burninggreenhouseindustrial revolutionnaturalrainfallrisingsunvolcanic and the production of 14burninggreenhouseindustrial revolutionnaturalrainfallrisingsunvolcanic gases. One of the main ones is carbon dioxide created by the chopping down and 14burninggreenhouseindustrial revolutionnaturalrainfallrisingsunvolcanic of trees. The fuel used in cars and machinery also creates this gas. Scientists say it is already too late to prevent global warming but we should still try to limit the impact. A change in temperature of under 14burninggreenhouseindustrial revolutionnaturalrainfallrisingsunvolcanic degree Centigrade is enough to make the sea level rise. The BBC's climate change experiment predicts a 14burninggreenhouseindustrial revolutionnaturalrainfallrisingsunvolcanic degree rise in temperature by 2080 with less 14burninggreenhouseindustrial revolutionnaturalrainfallrisingsunvolcanic and more droughts.
