Global Warming and the greenhouse effect are words that have been discussed in great detail constantly for the past twenty years. ... "Greenhouse effect is the effect produced as greenhouse gases allow incoming solar radiation to pass through the Earth's atmosphere, but prevent part of the outgoing infrared radiation from the Earth's surface and lower atmosphere from escaping into outer space- (EPA Global Warming Site). ...
The constant variation in the global climate is pushing many of our ecosystems towards thresholds of quick irreversible transformation, the approach to such tipping points is noticed by different transformations in the arctic tundra vegetation, widespread desertification of arid lands, and increase in freshwater inputs to the arctic seas. ... Arctic Ice Melting The arctic ice is known to provide large white surface for reflecting solar radiation away from the earth (Albedo effect ), but when these ice starts to melt it exposes a much darker part on the ocean surface, which absorbs more radiati...
