'''Anthropogenic global warming''' (AGW) is a [[liberal]] theory suggesting that human activity is causing the [[Earth]] to warm. The theory posits that [[greenhouse gas]]es, including carbon dioxide, methane, nitrous oxide, and water vapor, trap solar warmth on the planet. Computer models suggest that industrial and vehicular emissions could lead to catastrophic warming. [[Leftist]]s use this theory as a basis to propose cuts in energy production and consumption and to promote de-industrialization. (See: [[Atheism and climate change policies]]). This hoax is also used as way to sue energy companies for billions of dollars, which has hurt the value of those companies and their workers.
The rate of warming predicted by AGW theory is far higher than what has been observed so far. Based on an average of 102 climate models, the UN's Intergovernment Panel of Climate Change (IPCC) predicts that the lower troposphere should be warming at a rate of 3.1 degrees per century, according to an average of 102 climate models used by the Intergovernmental Panel on Climate Change (IPCC).<ref name="SpencerCSP2">"[https://www.newcriterion.com//cm/images/THE%20CLIMATE%20SURPRISE%20PAMPHLET.pdf The Climate Surprise Pamphlet]", ''The New Criterion'', 2016.

==Difficulties with the theory==
==History==
Although alleged climate scientists claim the theory of global warming dates from the 19th century, it gained its modern impetus among the The greenhouse effect was proposed by [[socialist]] [[totalitarian]] [[LeftJoseph Fourier]] in the 1980s1827. Unable to compete economically with [[The West]] and [[President Ronald Reagan]]'s defense modernization program, which ultimately bankrupted Swedish scientist Svante Arrhenius is sometimes considered the [[Soviet Union]], anti-capitalists in the United States and Europe began attacking the booming auto manufacturing,<ref><small>The legacy father of the global [[Cold War]] economy can be seen warming theory because of a paper he published in that 1896 on the loosers effect of [[World War II]] - [[Germany]] and [[Japan]] - carbon dioxide emissions.

Germany and Japan were allowed The idea that carbon dioxide emissions might lead to rebuild their economies around catastrophe comes from research on the automobile - provided the two refrained from competing Venusian atmosphere in the global aircraft industry1960s by Karl Sagan and other NASA scientists. World War II proved In the military doctrine of the superiority of airpower - whoever controls the skies controls the ground1970s, global cooling theories were more prominent than global warming theories. While Germany snd Japan do produce aircraftEven Steven Schneider, including military aircraftlater a promoter of global warming, it is strictly for their domestic markets and not for exportpublished a paper on global cooling.

===Origin===
In 1827, French scientist [[Joseph Fourier]] suggested that although the atmosphere allowed sunlight to pass through to warm the Earth, it blocked "dark heat" (infrared radiation) from the Earth and thus prevented energy from being transferred back into space.<ref name=Fourier>Fourier, Jean Baptist Joseph, "On the Temperatures of the Terrestrial Sphere in Interplanetary Space", Translated in ''The Warming Papers: The Scientific Foundation for Climate Change Forecast''. The relevant section is pp. 12-13.</ref> Fourier did make an unfortunate analogy between the Earth's atmosphere and a space enclosed by glass. All the same, it may not be fair to blame Fourier for the greenhouse effect meme. He also discussed convection as an alternative explanation and, as a good scientist, recommended an experiment to resolve the issue.
In 1861, Irish scientist John Tyndall measured the absorption of radiant energy by various gases in the atmosphere. He concluded that water vapor was the gas primarily responsible. It could therefore be considered the warming agent that Fourier hypothesized. Tyndall suggested that changes in humidity could bring about climate change.
{{cquote|And like most people we’d like to see the world a better place, which in this context translates into our working to reduce the risk of potentially disastrous climate change. To do that we need to get some broad based support, to capture the public’s imagination. '''That, of course, means getting loads of media coverage. So we have to offer up scary scenarios,''' make simplified, dramatic statements, '''and make little mention of any doubts we might have'''. This “double ethical bind” we frequently find ourselves in cannot be solved by any formula. Each of us has to decide what the right balance is between being effective and being honest. I hope that means being both.<ref>The quote is from ''Discover'', pp. 45–48, October 1989. See [https://www.weeklystandard.com/climategate-part-ii/article/610926 this link].</ref>}}
After Schneider abandoned his global cooling hobbyhorse and got on the global warming [[argumentum ad populum|bandwagon]], he never looked back. He was all about offering up "scary scenarios" in order to get "loads of media coverage." He had hoped to be honest, but, let's face it, nobody's perfect. Since he presents himself here as the high priest of climate science, it should be noted that Schneider's Ph.D. is in mechanical engineering.
===The IPCC===
<blockquote>Professor Phil Jones, director of the Climate Research Unit at the University of East Anglia, who found himself at the centre of the ‘Climategate’ scandal over leaked emails three years ago, would not normally be expected to agree with her.... Prof Jones also admitted that the climate models were imperfect: ‘We don’t fully understand how to input things like changes in the oceans, and because we don’t fully understand it you could say that natural variability is now working to suppress the warming. We don’t know what natural variability is doing.’</blockquote>
==Polar bears==
It was announced on the news that polar bears risk going extinct by the end of the twenty-first century if current carbon emissions continue.

[[Christopher Monckton]] wrote an article entitled "Climate sensitivity reconsidered" which states that the Intergovernmental Panel on Climate Change studies are flawed.<ref>Monckton, Christopher (July 2008).

:The present analysis suggests that the models failure of the IPCC's models to predict this and many other climatic phenomena arises from defects in its evaluation of radioactive the three factors whose product is climate sensitivity: ::Radiative forcing, ΔF;::The no-feedbacks climate sensitivity parameter κ; and ::The feedback multiplierƒ. In conclusion :Some reasons why the IPCC’s estimates may be excessive and unsafe are explained. More importantly, the conclusion is that , perhaps, there may be is no "Climate Crisis" “climate crisis”, and for that currently-fashionable efforts by governments to reduce anthropogenic CO<sub>2</sub> emissions are pointless, may be pointless or ill-conceived, and could even be harmful.
