The globes mood is constantly changing over time. Many climatologists believe that the temperature of the flat coat late fluctuates over time. In fact, some(prenominal) scientists estimate that amongst 15,000 and 30,000 years ago the world was covered by huge sheets of ice. This Period of time was knows as the sorbet Age. As the temperature of the Earth began to rise 7,000 years ago, than the Ice Age came to an end. From the late fourteenth century to the end of the 19th century, the Earth experienced a Little Ice Age. Extreme cold and harsh conditions caused several famines and the expansion of glaciers, most notably in the Alps, Scandinavia, Iceland and Alaska. However, by 1850 the temperature of the Earth had warmed considerably and scientists were looking for an answer. The first theory of globose warming came in 1824 when French mathematician Jean Baptiste Joseph Fourier discovered that the Earths temperature was slowly increasing. Fourier argued that the earths atmosphere traps solar radiation and reflects it back toward the earth.
In 1896 Svante Arrhenius a Swedish scientist that was the first to claim that fossil fuel conflagration may eventually result in enhanced world(prenominal) warming. He proposed a relation between atmospheric blow dioxide assiduousnesss and temperature.
He found that the average surface temperature of the earth is closely 15oC because of the infrared absorption capacity of water vapor and blow dioxide. This is called the natural greenhouse effect. Arrhenius suggested a doubling of the CO2 concentration would lead to a 5oC temperature rise. He and Thomas Chamberlin calculated that homo activities could warm the earth by adding carbon dioxide to the atmosphere. This research was a by-product of research of whether carbon dioxide would explain the causes of the great Ice Ages. This was not actually verified until 1987. After the discoveries of Arrhenius and Chamberlin the topic was forgotten for a very long time. At that...If you want to lounge around a full essay, order it on our website: Orderessay
