Climate change alarmism or global warming alarmism is a rhetorical style which stresses the potentially catastrophic effects of global warming as a technique for motivating public action. Public perception of the realities and risks associated with climate change forms a continuum in which people with "alarmist" views form one extreme along the continuum, and those commonly characterized as "denialists, "skeptics" or "naysayers" at the other extreme. The term "alarmist" also is often used by those who reject the scientific consensus on climate change as an epithet for those who broadly agree with the consensus view.

Alarmism is described as the use of a linguistic repertoire which communicates climate change using inflated language, an urgent tone and imagery of doom. In a report produced for the Institute for Public Policy Research Gill Ereaut and Nat Segnit reported that alarmist language is frequently employed by newspapers, popular magazine and in campaign literature put out by government and environment groups. It is difficult for the public to see climate change as urgent unless it is posed to them as a catastrophe, but using alarmist language is an unreliable tool for communicating the issue to the public. Instead of motivating people to action, these techniques often evoke "denial, paralysis apathy" and do not motivate people to become engaged with the issue of climate change. In the United Kingdom, alarmist messages are often subject to "subtle critique" in the left-leaning press, while the right-leaning media often "embrace" the message, but undermine it using a "climate skeptic" frame. In the context of the climate refugees—the potential for climate change to displace people—it has been reported that "alarmist hyperbole" is frequently employed by private military contractors and think tanks.

People who hold alarmist views of climate change represent one end of a continuum in public perceptions of climate change. Allan Leiserowtiz found that alarmists made up about 11% of the United States population, while "naysayers", who have a skeptical or cynical view of climate change, make up about 7% of the population. The remainder of the public lay between these two extremes. Their perception of climate change was similar to that of the alarmists, but they differed significantly from them on questions related to perceived risk.

Media coverage

Minority views—both alarmist and denialist—were reported to get disproportionate attention in the popular press, especially in the United Kingdom. One of the consequences of this is a portrayal of risks well beyond the claims actually being made by scientists. Others have noted the tendency for journalists to overemphasize the most extreme outcomes from a range of possibilities reported in scientific articles. A study that tracked press reports about a climate change article in the journal Nature found that "results and conclusions of the study were widely misrepresented, especially in the news media, to make the consequences seem more catastrophic and the timescale shorter."

Views of scientists

Scientists who agree with the consensus view on global warming often have been critical of those who exaggerate or distort the risks posed by global warming. Stephen Schneider has criticized such exaggeration, stating that he "disapprove of the 'ends justify the means' philosophy" that would exaggerate dangers in order to spur public action. Mike Hulme, professor at the University of East Anglia and former director of the Tyndall Centre for Climate Change Research, describes such exaggerations as "self-defeating," in that they engender feelings of hopelessness rather than motivating positive action. Hans von Storch has objected to "alarmists think that climate change is something extremely dangerous, extremely bad and that overselling a little bit, if it serves a good purpose, is not that bad."

Scientists also have criticized press sensationalism in reporting on climate change. Myles Allen, director of the Climateprediction.net experiment, criticized press reporting that seized on the extreme end of predictions from the experiment rather than the much more likely outcome of moderate warming.
