'''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]]).

The rate of warming predicted by AGW 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.<ref name="SpencerCSP2">"[https://www.newcriterion.com//cm/images/THE%20CLIMATE%20SURPRISE%20PAMPHLET.pdf The Climate Surprise Pamphlet]", ''The New Criterion'', 2016.

==History==

The greenhouse effect was proposed by [[Joseph Fourier]] in 1827. Swedish scientist Svante Arrhenius is sometimes considered the father of global warming theory because of a paper he published in 1896 on the effect of carbon dioxide emissions. Arrhenius thought of global warming as a positive thing. The idea that carbon dioxide emissions might lead to catastrophe comes from research on the Venusian atmosphere in the 1960s by Karl Sagan and other NASA scientists. In the 1970s, global cooling theories were more prominent than global warming theories. Even Steven Schneider, later a promoter of global warming, published a paper on global cooling. As a result of the energy crisis of the 1970s, the enviromentalist movement adopted an agenda of conservation and renewable energy. With global warming as its flagship theory, the movement could continue promoting its 1970s agenda long after the original justifications for it had disappeared. Schneider offered up "scary scenarios," as he called them, to promote the theory.
