Thanks to the release of Al Gore's latest effort on global warming - this time in book and movie form - climate change is the hot topic in press rooms around the globe. It isn't the first time.
The media have warned about impending climate doom four different times in the last 100 years. Only they can't decide if mankind will die from warming or cooling.
As the noise from the controversy has increased, it has drowned out any debate. Journalists have taken advocacy positions, often ignoring climate change skeptics entirely. One CBS reporter even compared skeptics of manmade global warming to Holocaust deniers.
The Society of Environmental Journalists Spring 2006 SEJournal included a now-common media position, arguing against balance. But that sense of certainty ignores the industry's history of hyping climate change - from cooling to warming, back to cooling and warming once again.
The Media Research Center's Business & Media Institute (formerly the Free Market Project) conducted an extensive analysis of print media's climate change coverage back to the late 1800s.
It found that many publications now claiming the world is on the brink of a global warming disaster said the same about an impending ice age - just 30 years ago. Several major ones, including The New York Times, Time magazine and Newsweek, have reported on three or even four different climate shifts since 1895.
In addition, BMI found:
New York Times the Worst: Longtime readers of the Times could easily recall the paper claiming 'A Major Cooling Widely Considered to Be Inevitable,' along with its strong support of current global warming predictions. Older readers might well recall two other claims of a climate shift back to the 1800s - one an ice age and the other warming again. The Times has warned of four separate climate changes since 1895.
