What is Global Warming ?







Wikipedia says:


Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.
Global average air temperature near the Earth's surface rose during the past century. The Intergovernmental Panel on Climate Change (IPCC) concludes, "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations, which leads to warming of the surface and lower atmosphere by increasing the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes have probably had a small warming effect from pre-industrial times to 1950, but a cooling effect since 1950. The basic conclusions have been endorsed by at least 30 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries.

Based on "Stop Global Warming organsition":



The Earth as an ecosystem is changing, attributable in great part to the effects of globalization and man. More carbon dioxide is now in the atmosphere than has been in the past 650,000 years. This carbon stays in the atmosphere, acts like a warm blanket, and holds in the heat — hence the name ‘global warming.’
The reason we exist on this planet is because the earth naturally traps just enough heat in the atmosphere to keep the temperature within a very narrow range - this creates the conditions that give us breathable air, clean water, and the weather we depend on to survive. Human beings have begun to tip that balance. We've overloaded the atmosphere with heat-trapping gasses from our cars and factories and power plants. If we don't start fixing the problem now, we’re in for devastating changes to our environment. We will experience extreme temperatures, rises in sea levels, and storms of unimaginable destructive fury. Recently, alarming events that are consistent with scientific predictions about the effects of climate change have become more and more commonplace.

so, simply:

Global warming is the increase of the temperature of planet earth. The green house effect is letting the heat in and preventing it from getting away from the planet. This causes ice to melt leading to an increase in earth's water level (everything will eventually melt or drawn).
The atmosphere of the earth itself is doing the same thing towards the heat absorbed from the sun. Which means that the heat the earth absorbs stays around and can’t be get rid of.
Many factors contributed in making the atmospheric shell as reflective as it is. One of the main reasons is the Co2 emissions that are launched by human activities and late technologies.
The results would be total destruction of the plant life. With time the climate would start to change creating disasters killing the plant life on earth slowly then to affecting the animal life also (including humans).




Good luck every body..
