evidence: In 1938 Guy Stewart Callendar attempted to revive Arrhenius's greenhouse-effect theory. Callendar presented evidence that both temperature and the CO2 level in the atmosphere had been rising over the past half-century, and he argued that newer spectroscopic measurements showed that the gas was effective in absorbing infrared in the atmosphere. Nevertheless, most scientific opinion continued to dispute or ignore the theory.[50] [...] Such media coverage heralding the coming of a new ice age resulted in beliefs that this was the consensus among scientists, despite this not being reflected by the scientific literature. As it became apparent that scientific opinion was in favor of global warming, the public began to express doubt over how trustworthy the science was.[59] The argument that scientists were wrong about global cooling, so therefore may be wrong about global warming has been called "the "Ice Age Fallacy" by Time author Bryan Walsh.[79] [...] - ^ Powell, James Lawrence (20 November 2019).
