a person nervous by nature who always expects danger and disturbs/worries others by saying so;
a person who raises an alarm when there is no reason to be alarmed, usually spreading rumours or false ideas, like, for example, a person who keeps saying that an expired artificial satellites will fall down to earth killing all of us or that the world will come to an end in the year 2012,
Most people now call the former US president, Al Gore, the renowned environmentalist who has been warning people of the dangers of global warming, an alarmist because, they think, there is no evidence that the global warming is going to end our lives on this planet.
Some alarmists scare others for fun, like pranksters do silly things to fool others.
Even the lock-step libs at AP admit that emeritus professor William Gray of the atmospheric science department at Colorado State University “has become known as America’s most reliable hurricane forecaster” over the past 24 years, so it should come as a relief to anyone tempted to take Al Gore’s frightening ravings seriously that Professor Gray regards the Goracle as “a gross alarmist.”
An excerpt from CNN World News:
“It is right to take sensible measures. But it is unnecessary to be alarmist,” Home Secretary Jack Straw told Parliament.
