Climate change alarmism or global warming alarmism is a critical description of a rhetorical style which stresses the potentially catastrophic effects of predicted, drastic changes in the earth's climate, which usually means global warming.

Public perception of the realities and risks associated with climate change have been described as forming 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.

Alarmism as a pejorative

The term alarmist is commonly used as a pejorative by critics of anthropogenic global warming theory to describe those that endorse the concept. MIT meteorologist Kerry Emanuel wrote that labeling someone as an "alarmist" is "a particularly infantile smear considering what is at stake." He continued that using this "inflammatory terminology has a distinctly Orwellian flavor."

The term is also used to describe, usually in a pejorative way, an alleged consensus of scientists and media said to have propagated a global cooling scare in the 1970s. The purported episode of alarmism related to global cooling has been compared with the perceived alarmism tied to global warming.

Alarmism as an extreme position

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 Koch Industries support a foundation which, Charles Koch has said, counters "climate change alarmism", among other things "that threaten to destroy America as we know it.". In the context of 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.

Looking at 2003 United States popular survey data in 2005, Anthony A. Leiserowitz identified an "interpretive community with high-risk perceptions of climate change" and called them alarmists. The data found that they made up about 11% of the US population, while those he called naysayers, an "interpretive community that perceived climate change as a very low or nonexistent danger", made up about 7% of the population. The remainder of the public lay between these two extremes, including some who confused climate change and stratospheric ozone depletion. Thus individuals differed significantly when questioned about 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

The consensus view based on all available data and scientific modelling is "that today’s climate is far out of equilibrium with current climate forcings". This means that large-scale changes in the Earth's climate are already in motion, and will not reverse even if no more greenhouse gases are emitted into the atmosphere. Estimates are that it is necessary to maintain levels of atmospheric CO₂ at or below 350ppm to avoid "deletrious" effects and "to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted". The atmospheric CO₂ level is currently above 385ppm and still rising, which has already led to measurable effects over the last century including average temperature rises, the retreat of Alpine glaciers, reductions in polar ice cover and die-back of coral reefs due to ocean acidification and sea temperature rises. Global tipping points and the risk of irreversible changes to the Earth's climate are difficult to quantify but are cited as causes for grave concern by mainstream climate science.

Scientists who agree with this 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."

MIT atmospheric physicist Richard Lindzen, who believes that the effects of global warming will be milder than the current consensus estimate, has written:

Unfortunately, a significant part of the scientific community appears committed to the maintenance of the notion that alarm may be warranted. Alarm is felt to be essential to the maintenance of funding. The argument is no longer over whether the models are correct (they are not), but rather whether their results are at all possible.

Hurricane researcher William Gray stated that Al Gore is a "gross alarmist" regarding his Oscar-winning documentary about global warming, An Inconvenient Truth. "He's one of these guys that preaches the end of the world type of things. I think he's doing a great disservice and he doesn't know what he's talking about" said Gray.

In a 2009 interview with Fortune Magazine about signing the 2003 American Geophysical Union (AGU) statement, climatologist John Christy said: "As far as the AGU, I thought that was a fine statement because it did not put forth a magnitude of the warming. We just said that human effects have a warming influence, and that's certainly true. There was nothing about disaster or catastrophe. In fact, I was very upset about the latest AGU statement . It was about alarmist as you can get."

Almost exactly 30 years ago the world was in another panic about climate change. However, it wasn't the thought of global warming that concerned us. It was the fear of its opposite, global cooling.

The most-quoted ice-age alarmist of the 1970s became, in a neat public-relations pivot, one of the most quoted global-warming alarmists of the 1990s."
