Global Warming and the Greenhouse Effect Essay -- Environmental Global

Global Warming and the Greenhouse doThe nursery force, in environmental science, is a popular term for the effect that certain variable constituents of the Earths lower atmosphere have on come on temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the glasshouse effect.). The gases--water vapor (H2O), carbon dioxide (CO2), and methane (CH4)--keep ground temperatures at a spheric just of about 15 degrees C (60 degrees F). Without them the average would be below the freeze point of water. The gases have this effect because as incoming solar ray strikes the surface, the surface gives off infrared radiation, or heat, that the gases trap and keep come along ground level. The effect is comparable to the way in which a greenhouse traps heat, hence the term. Environmental scientists are concerned that changes in the variable contents of the atmosphere--particularly changes caused by human activities--could cause the Earths su rface to warm up to a dangerous degree. Since 1850 there has been a mean place upright in global temperature of approximately 1? C (approximately 1.8? F). Even a limited bob up in average surface temperature might lead to at to the lowest degree partial melting of the polar icecaps and hence a major rise in sea level, along with other severe environmental disturbances. An vitrine of a runaway greenhouse effect is Earths near-twin planetary neighbor Venus. Because of Venuss buddy-buddy CO2 atmosphere, the planets clo...
