	Global warming - Wikipedia, the free encyclopedia
		Global warmingis the main effect of owen haha 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.
		Global warming from CO radiative forcing is expected (perhaps somewhat surprisingly) to cool the stratosphere.

	Global warming
		Global warming is an increase over time of the average temperature of Earth's atmosphere and ocean s.
		It is though by geologists that the Earth experienced global warming in the early Jurassic period, with average temperatures rising by 5° Celsius (9° Fahrenheit).
		Global warming causes the sea level to rise mainly because sea water expands as it warms, but some scientists are concerned that in the future, the polar ice cap s and glacier s may melt.

	Global warming controversy - Wikipedia, the free encyclopedia
		Some opponents of global warming theory give more weight to data such as paleoclimatic studies, temperature measurements made from weather balloons, and satellites which they claim show less warming than surface land and sea records, though early balloon records have been shown to be possibly over-inflated due to mechanical design flaws in the sensors.
		Global warming skeptics dispute the claim that (or relevance of) a consensus of scientists supports the view of global warming presented by the IPCC, and say that even the IPCC report authors do not all support the reports.
		Another argument from the global warming skeptics, is that records of temperature change are wrong because temperature monitoring stations are located in urban areas and as such the measurements they take are distorted by the heat of the city (from cars, house heating etc).

		It is thought by geologists that the Earth experienced global warming in the early Jurassic period, with average temperatures rising by 5° Celsius (9° Fahrenheit).
		Some scientists now consider that the effects of the recently recognized phenomena of global dimming (the reduction in sunlight reaching the surface of the planet, possibly due to aerosols) may have masked some of the effect of global warming.

		Global warming theories attempt to account for the rise in average global temperatures since the late 19th century (0.6 ± 0.2°C) [1] (http://www.grida.no/climate/ipcc_tar/wg1/figspm-1.htm) [2] (http://www.whitehouse.gov/news/releases/2001/06/20010611-2.html) and assess the extent to which the effects are due to human causes.
		The anthropogenic greenhouse gas with the largest effect is carbon dioxide although the bulk of the greenhouse effect is actually due to water vapor.
		Global warming theories attempt to assess the extent to which increases in carbon dioxide levels affect the global climate though both direct and indirect means.

	Anthropogenic global warming (Site not responding. Last check: 2007-11-07)
		Anthropogenic global warming refers to that portion of global warming attributed to human activity, including but not limited to that caused by the introduction of greenhouse gases into the atmosphere.
		Despite the general agreement that temperatures have risen in the last century (somewhere between 0.4 and 0.8°C), theproportion of this warming that is due to human influence is still open to question.
		In 2001 the TAR upgraded this by saying "There is new and stronger evidence that most of the warming observedover the last 50 years is attributable to human activities" [1].

		The implication is that anthropogenic global warming presumes an anthropocentrism.
		Richard Tol and Aart de Vos subject global warming to a Bayesian analysis comporting with the mainstream consensus that anthropogenic forcing, especially the addition of carbon dioxide, is the primary factor contributing to increased surface temperatures.
		Under such an analysis, the assertion that anthropogenic factors are necessary for the existence of global warming is equivalent to the anthropic principle cosmologist's claim that anthropic observation is necessary for the existence of the universe.

		The fate of anthropogenic CO2 in the atmosphere is uncertain: its uptake into the ocean; the biological pump; the missing carbon sink.
		A global warming trend is calculated to reduce the latitudinal temperature gradient and therefore the driving force for storms and severe weather.
		Global agriculture will likely benefit from climate warming and increased precipitation; increased CO2 leads to more rapid plant growth; increased nocturnal and winter warming leads to a longer growing season.

	NCPA - Global Warming - Human Induced Warming Evaporates In Thin Air (Site not responding. Last check: 2007-11-07)
		But advocates of human-induced (anthropogenic) global warming assume that as greenhouse gases increase, water vapor and upper-level cloudiness will also rise and lead to accelerated warming -- a positive feedback loop.
		However, the global general circulation models which simulate significant human-induced warming are incorrectly structured to give this positive feedback loop -- thus their assumptions are not realistic.
		The small warming that has occurred is likely a result of natural alterations in global ocean currents -- as yet little understood -- which are driven by variations in the salinity of seawater.

	Goodbye to Anthropogenic Global Warming - Joe Mariani - MensNewsDaily.com™
		The keystone of anthropogenic global warming is that the global mean temperature has risen sharply in the last 150 years, since scientists began to measure it.
		Yet Mars is also experiencing global warming, which strengthens the hypothesis that Earth's global warming is heliogenic, or sun-based, to the point of positive proof.
		In the absence of any evidence to support it, the anthropogenic global warming argument is as dead as the dinosaurs whose ancient remains I put in my gas tank this afternoon.

		We know that anthropogenic emissions of greenhouse gases can influence the climate and the temperature increase witnessed during the 20th century can only be explained by the increased emissions of carbon dioxide from our use of coal, oil and natural gas which make up the vast majority of greenhouse gas emissions.
		Our page "greenhouse gases and climate change" describes in detail the causes of anthropogenic global warming, its effects and consequences and how great the emissions are from different countries.
		Anthropogenic emissions of greenhouse gases increase the temperature on Earth, disturbing its climate.

	Global Warming
		Although the global temperatures of the Holocene period appear relatively stable compared to the periods before it, there has been variability in climate due to solar irradiance and other natural phenomena prior to anthropogenic CO emissions.
		This is an example of a positive feedback loop that could intensify the effects of global warming caused by humans.
		Surface temperatures in the Arctic winter are expected to be 2-2.4 times greater than the annual average warming over the rest of the globe, while summer surface warming is expected to be 0.5-0.7 times that of the global average (Maxwell, 1992).

	EPA : Global Warming : Emissions
		Often, estimates of greenhouse gas emissions are presented in units of millions of metric tons of carbon equivalents (MMTCE), which weights each gas by its GWP value, or Global Warming Potential.
		This excerpt describes the characteristics of each of the various greenhouse gases and discusses the concept of Global Warming Potential (GWP) values.
		Inventories of natural and anthropogenic emissions are used by scientists as inputs to air quality models, by policy makers to develop strategies and policies or track progress of standards, and by facilities and regulatory agencies to establish compliance records with allowable emission rates.

	Global Warming: Fact or Fiction? (Site not responding. Last check: 2007-11-07)
		This project explored the various facts, theories, and bodies of research surrounding the global warming issue in an attempt to determine whether or not anthropogenic global warming exists (to an extent beyond that inherent in the nature of our planet) and how great its impact is, will, or could be.
		Since the main method of theorizing about current and future warming is through computerized climate modeling, this project focused on these models, the difficulties in using them, and the impact these models and global warming itself may have on everyday life.
		While much time has been given to passionate appeals to the emotions (by those on either side of the issue), this project attempted to approach the problem in a rational, logical manner and give a fair view of the problems with the theory and the current research to remedy them.
