	NRDC: Global Warming Basics
		Global warming is already causing damage in many parts of the United States.
		Of course, the impacts of global warming are not limited to the United States.
		Global warming is a complex phenomenon, and its full-scale impacts are hard to predict far in advance.

	Global Warming - MSN Encarta (Site not responding. Last check: )
		Global Warming, increase in the average temperature of the atmosphere, oceans, and landmasses of Earth.
		The chief cause of this warming is thought to be the burning of fossil fuels, such as coal, oil, and natural gas, which releases into the atmosphere carbon dioxide and other substances known as greenhouse gases.
		This temperature rise is expected to melt polar ice caps and glaciers as well as warm the oceans, all of which will expand ocean volume and raise sea level by an estimated 9 to 100 cm (4 to 40 in), flooding some coastal regions and even entire islands.

	Global warming - Wikipedia, the free encyclopedia
		Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades.
		Warming is expected to affect the number and magnitude of these events; however, it is difficult to connect particular events to global warming.
		Global warming from carbon dioxide radiative forcing is expected (perhaps somewhat surprisingly) to cool the stratosphere.

	Global Warming -- Research Issues
		This warming is largely attributed to the increase of greenhouse gases (primarily carbon dioxide and methane) in the Earth's upper atmosphere caused by human burning of fossil fuels, industrial, farming, and deforestation activities.
		Finally, human health is also at stake, as global warming may result in the spreading of certain diseases such as malaria, the flooding of major cities, a greater risk of heat stroke for individuals, and poor air quality.
		While a component of recent global warming may have been caused by the increased solar activity of the last solar cycle, that component was very small compared to the effects of additional greenhouse gases.

	Global Warming Myths and Facts - Environmental Defense
		The most respected scientific bodies have stated unequivocally that global warming is occurring, and people are causing it by burning fossil fuels (like coal, oil and natural gas) and cutting down forests.
		This is actually in line with climate model predictions that global warming would lead to a short-term accumulation of ice in the cold interior due to heavier snowfall.
		Global warming, on the other hand, is the increase in the earth's average temperature due to the buildup of CO and other greenhouse gases in the atmosphere from human activities.

		Evidence of global warming is uneven with certain places, especially the north shore of Alaska, showing dramatic rises temperature far above the average for the globe as a whole [1].

	Global warming - Facts, Information, and Encyclopedia Reference article (Site not responding. Last check: )
		Global warming describes an increase in the average temperature of the Earth's atmosphere and oceans.
		The terms global warming or anthropogenic global warming are also used to describe the theory that increasing temperatures are the result of a strengthening greenhouse effect caused primarily by man-made increases in carbon dioxide and other greenhouse gases.
		In common usage, the term "global warming" generally implies a human influence — the more neutral term climate change is usually used for a change in climate with no presumption as to cause and no characterization of the kind of change involved, such as the Ice Ages.

		Global warming is the fourth of a series of briefing documents on the problems of power consumption, posed by the steady depletion of fossil fuels and most particularly of pumpable oil.
		While the general consensus is that global warming is occurring and is in part caused by human activity [anthropogenic], anyone who tells you that global warming is understood and proven (or disproven), followed by some trite reason, simply does not understand the situation.
		The influence of the Sun on the Earth is seen increasingly as one cause of the observed global warming since 1900, along with the emission of the greenhouse gas, carbon dioxide, from the combustion of coal, gas, and oil.

		Much of the debate surrounding global warming has centered on the accuracy of scientific predictions concerning future warming.
		To predict global climatic trends, climatologists accumulate large historical databases and use them to create computerized models that simulate the earth's climate.
		Nonetheless, for some time there has been general agreement that at least part of the observed warming is the result of human activity, and that the problem needs to be addressed.

		"Global warming" refers to the increase of the Earth's average surface temperature, due to a build-up of greenhouse gases in the atmosphere.

	NCDC: Global Warming
		Global surface temperatures have increased about 0.6°C (plus or minus 0.2°C) since the late-19th century, and about 0.4°F (0.2 to 0.3°C) over the past 25 years (the period with the most credible data).
		Temperature trends in the lower troposphere (between about 2,500 and 26,000 ft.) from 1979 to the present, the period for which Satellite Microwave Sounding Unit data exist, are small and may be unrepresentative of longer term trends and trends closer to the surface.
		Global mean sea level has been rising at an average rate of 1 to 2 mm/year over the past 100 years, which is significantly larger than the rate averaged over the last several thousand years.
