*'''Carbon dioxide is not a major greenhouse gas.'''

*'''Carbon dioxide is not a major greenhouse gas.''' The level of CO₂ in the Earth's atmosphere is only 400 parts per million. Ninety to 95 percent of the greenhouse effect is due to water vapor.<ref>Friedenreich and Ramaswamy, "Solar Radiation Absorption by Carbon Dioxide, Overlap with Water, and a Parameterization for General Circulation Models," Journal of Geophysical Research 98 (1993):7255-7264)</ref> There are humidity measurements going back to 1948, and no upward trend -- as there would be if water vapor was in fact a "positive feedback."<ref>[https://wattsupwiththat.com/global-climate/ global climate]</ref>

*'''The Earth has warmed or cooled many times. Historically, warm periods are associated with favorable climate.''' The [[Roman Warm Period]] of ancient times was followed by the Dark Ages Cold Period of the Early Middle Ages. The Medieval Warm Period lasted from 900 to 1300. From the 14th century to the early 19th century, there was a Little Ice Age.<ref>Bastasch, Michael, "[http://dailycaller.com/2013/12/13/study-earth-was-warmer-in-roman-medieval-times/ Study: Earth was warmer in Roman, Medieval times]", ''The Daily Caller''</ref>

*'''The attraction of the theory is that it supports a political agenda.''' The environmentalist agenda of renewables, solar energy, conservation, and world government was put together in the 1970s in response to the energy crisis and to the overpopulation scare. At that time, most scientists thought the Earth was cooling.<ref>[http://realclimatescience.com/the-corrupt-history-of-nasa-temperature-history/ The corrupt history of NASA temperature history.</ref> Steven Schneider, godfather of the AGW movement, was a global cooling believer in the early 1970s. If the carbon dioxide level in the atmosphere is too high, this can be addressed by promoting plant growth in the oceans.<ref>Carrington, Damian, "[https://www.theguardian.com/environment/2012/jul/18/iron-sea-carbon Dumping iron at sea can bury carbon for centuries, study shows]" ''The Guardian'', 18 July 2012</ref> Such technical fixes lack appeal because AGW is less about carbon dioxide than about creating an additional set of justifications for the anti-energy cause. Scratch an AGW believer and there is an overpopulationist or a world government socialist underneath.
