from the warm current because it is so far north latitude. Europe's vegetation would drastically die off from the sudden difference in its environment, and impact Europe in many ways. There is already evidence that this happened at one point in time. Also, this is only one of many reactions that could happen to earth. One of the major reasons why greenhouse gases have increased drastically over time is because of industrialization. "Once, all climate changes occurred naturally. However, during the Industrial Revolution, we began altering our climate and environment through changing agricultural and industrial practices. Before the Industrial Revolution, human activity released very few gases into the atmosphere, but now through population growth, fossil fuel burning, and deforestation, we are affecting the mixture of gases in the atmosphere." (EPA web page) Some of the greenhouse gases occur naturally in earth's atmosphere, but some of them are increased in the atmosphere due to human activities. Carbon dioxide is one of the gases, which occurs naturally in the atmosphere, but at the same time is increased drastically by human intervention. Nearly 80% of carbon dioxide in the atmosphere comes from fossil fuel combustion, 17% from deforestation, and 3% from concrete production. Other forms of carbon dioxide production come from solid waste and wood products being burned. Substances that absorb carbon dioxide, technically known as "sinks", are the oceans (water) and land based plants (terrestrial biomass). (Lecture 10/4/00, Sampson) Methane is another important greenhouse gas, which is very potent when it comes to heat absorption. Methane can absorb 27 times more heat than carbon dioxide. Also 28% of methane comes from fossil fuel combustion, while rice patty agriculture, domestic animal waste, sewage treatment, landfills, and biomass burning attribute to the increase. Methane's two major sinks are chemical reactions, and also soil absorp...
