Global warming

The threat of global warming was downplayed in the "Environmental Hysteria" episode, contradicting the evidence as presented by the established scientific consensus. [14] Some environmentalists have pointed out that both Penn Jillette and Teller are research fellows of the limited government and free market advocacy group the Cato Institute,[15][16] which receives contributions from various individuals and companies, including ExxonMobil,[17] which itself has been the favored target of criticism for funding of what has been coined "climate change denial" by several environmental organizations, The Royal Society, and several US congressmen. However, donations to the Cato Institute by ExxonMobil between the years of 1991 and 2004 totaled only $90,000[1], a demonstrably insignificant percentage of the Cato Institute's annual revenues of over $22.5 million (2005)[2]. Also, it should be noted that as research fellows, Penn Jillette and Teller are not actually paid employees of the Cato Institute and as such would receive neither funding nor direction from the Institute as to the content of the television series.

In the "Environmental Hysteria" program, Jerry Taylor from CATO claims that scientists predicted an ice age in the 1970s, although these predictions of global cooling never occurred in peer-reviewed scientific literature.[18] Despite the reference to scientific data, no mainstream scientist from the area of climatology is present in the episode, and Penn and Teller instead rely on figures such as the statistician Bjørn Lomborg and critic Patrick Moore. [19] (See also Global warming controversy.)

The same episode disputes current levels of species extinction, although much of the scientific literature projects very high species extinction levels. [20][21] (See also Holocene extinction event.)
