'''Anthropogenic global warming''' (AGW) is an unproven theory that insists human activity is causing the [[Earth]] to warm catastrophically. 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 require cuts in energy production and consumption and to promote de-industrialization.

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.

An analysis of weather station data by U.S. climate researcher [[Roy Spencer]] shows no significant warming since 1943. Unlike the official weather station record, Spencer's data includes only those stations that recorded temperature at a consistent time of day.<ref name="Spencer" /> The heating predicted by AGW but not detected in the temperature record is sometimes said to be accumulating in the oceans.

The theory that "greenhouse gases" have a greater warming effect than other gases goes back to the 19th century. The idea that carbon dioxide emissions might lead to catastrophic warming was introduced by Carl Sagan in the 1960s. He was inspired by research on the atmosphere of Venus. Around 1978, the environmental movement decided to promote Sagan's theory. The movement was already advocating energy conservation and renewables as a response to the "energy crisis." That is to say, a desired political outcome was agreed upon and then a "scientific" justification was developed.

Proponents of the global warming theory advocate for conversion to electric vehicles without expanding the electric power grid, which can only be powered by coal-burning power plants, fossil fuel, or nuclear energy. So-called renewable energy sources, solar and wind, cannot provide enough capacity to recharge hundreds of millions of electric vehicles.
