Spectrum of Opinion

 

Environmentalists

(hot on warming)

Scientists

(emphasize complexity)

Contrarians

(cool on warming)

The image above represents the spectrum of opinion concerning the global warming/climate change debate. The hot colors, on the far left of the spectrum represent the environmentalists who are convinced that humankind is causing global warming and who are eager to implement international regulations on carbon dioxide and other emissions. The middle of the spectrum represents the position of most scientists actively engaged in climate research. They are involved in a complex analysis of climate that includes modeling the climate system and monitoring global temperature trends and other meteorological variables. On the far right, represented by the cool colors of the spectrum, are the contrarians. They emphasize major uncertainties within the climate community about mechanisms that may be influencing the climate, point out the possible benefits of elevated carbon dioxide levels, and oppose any policies to combat a possibly nonexistent global warming trend.
