  Global warming - Wikipedia, the free encyclopedia
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.
Global warming from CO radiative forcing is expected (perhaps somewhat surprisingly) to cool the stratosphere.

Global warming is the increase over time of the average temperature of Earth's atmosphere and oceans.
Increasing global temperature means that ecosystems may change; some species may be forced out of their habitats (possibly to extinction) because of changing conditions, while others may spread.
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 caps[?] and glaciers may melt.

 Status of the "global warming" hypothesis   (Site not responding. Last check: 2007-11-07)
The hypothesis that changes in concentrations of greenhouse gases, such as water vapour and carbon dioxide, could cause global warming was already postulated by Tyndall as early as 1861.
Such global simulations in turn are the basis for projecting the nature and effects of global climate variability and change, such as that due to a continued enhancement of the greenhouse effect.
Mitigating the causes of global warming implies limiting the rates and magnitudes of increases in atmospheric concentrations of greenhouse gases, either by reducing emissions or by increasing sinks for atmospheric CO2.

 Null Hypothesis - Global warming and frozen confectionary   (Site not responding. Last check: 2007-11-07)
Global warming has been a matter of great debate for many years; indeed it was French mathematician Jean-Baptiste-Joseph de Fourier who first raised the possibility that gaseous emissions into the atmosphere could cause temperature increases as early as 1820.
However, there still remains a certain amount of debate as to whether global warming is an actual phenomenon, or whether it is merely a conspiracy put forward by evil anti-capitalists hell-bent on bringing about the end of economy, society and the manner of life to which we are accustomed.
Defined as a slow gradual increase in the Earth's surface temperature caused by the increase of ‘greenhouse gases’ in the atmosphere, global warming seems to be responsible for changes in world climate patterns.

 GSFC Press Release 98-181   (Site not responding. Last check: 2007-11-07)
The greenhouse gases in the atmosphere that cause global warming are increasing much more slowly than assumed in climate predictions of the Intergovernmental Panel on Climate Change (IPCC), according to a new analysis of the growth rates of the heat-trapping gases.
Several key factors influencing global temperature – increases in clouds and small particles (aerosols) that tend to cool the Earth – are so poorly known that without new research and observations in these areas, reliable predictions of future warming are not possible.
Because of this reduced warming, the relatively small warming caused by a hypothesized increase in the Sun’s radiation output "may play a larger role in long-term climate change than inferred by comparison with greenhouse gases alone," according to the study’s authors.

 Alexander Cockburn vs. the Global Warming Hypothesis   (Site not responding. Last check: 2007-11-07)
It is refreshing to see someone on the Left take a skeptical view of global warming and especially the summary reports by the Intergovernmental Panel on Climate Change, which are essentially political rather than scientific in nature.
An interesting example of just how far scientists are from understanding global climate change was illustrated by a study recently published in Nature which most of the media trumpeted as further proof of global warming.
The study was a fascinating example of ingenuity whereby Dr. John Harries led a team that used satellite data from the past three decades to confirm that the amount of infrared radiation leaving the Earth is declining, meaning that more if it is somehow being trapped in the Earth's atmosphere, probably by manmade greenhouse gases.

Many pro warming studies focus on the last 1000 years or even shorter data sets, which tend to mis-represent and sensationalize recent changes, when in fact the data are consistent with longer term historical variations.

Within the last 50 years we have experienced major increases in the release into the atmosphere of the so-called greenhouse gases which some climatologists and environmentalists have argued are causing global warming and raising the possibility of catastrophic climatic changes.

Typically they also claim that human-induced global warming has already begun and point to increases in global temperatures, as measured by land-based thermometers over the last century, as evidence for their proposition.
This is especially significant because the global warming hypothesis predicts that temperatures in the upper atmosphere should show warming prior to warming at the surface.
In fact, this appears to be evidence that directly contradicts the global warming hypothesis, suggesting that the surface warming is not part of a pattern of human-induced global warming.

Global warming alarmists see a future plagued by catastrophic flooding, war, terrorism, economic dislocations, droughts, crop failures, mosquito-borne diseases, and harsh weather--all caused by man-made greenhouse gas emissions.
The issue of global warming has garnered significant international attention through the Kyoto Treaty, which requires signatories to reduce their greenhouse gas emissions by considerable amounts below 1990 levels.
The treaty explicitly acknowledges as true that man-made emissions, principally from the use of fossil fuels, are causing global temperatures to rise, eventually to catastrophic levels.
