EDITOR'S NOTE: OUR ENVIRONMENT ONLINE was originally published in 1995. In that publication we reprinted a piece entitled "DEBUNKING RUSH LIMBAUGH ON THE ENVIRONMENT." It was originally published by the Environmental Defense Fund in New York. Over the years it has consistently been the most viewed page on this website. 

Introduction: Rush Limbaugh's best-selling books The Way Things Ought to Be and See, I Told You So  are full of statements on the environment that are misleading, distorted, and  factually incorrect. Indeed, Limbaugh's claims often fly in the face of carefully  considered scientific evidence, and put him in opposition to the views of the most eminent scientific experts, as reflected in the conclusions of such esteemed  bodies as the National Academy of Sciences and the World Meteorological Organization.  Though Limbaugh likes to frame the debate as a contest between him and the  "environmental wackos", it is really Limbaugh's word against the overwhelming tide  of scientific knowledge. Unfortunately, his fallacies have created a great deal of confusion  and have perpetuated the misunderstanding of a number of critical issues.  It is important that Limbaugh's disinformation campaign be confronted  directly and that the resulting misconceptions be cleared up. Here we present several examples of erroneous statements from Limbaugh's books,  followed by the actual scientific facts. In each instance, we have included  sources in the scientific and professional literature, unlike Limbaugh,  who offers little or no evidence to back up his claims. Chlorofluorocarbons and Ozone Depletion: RUSH FICTION:  Limbaugh proposes that environmental "alarmists and prophets of  doom" have exaggerated the problem of ozone depletion, suggesting  that it has been limited to "occasional reduced levels of ozone over Antarctica." 1/ SCIENTIFIC FACT:  Substantially reduced levels of ozone have been measured over  most of the globe, including North America, Europe, and elsewhere.   In fact, scientists have observed a thinning of the ozone layer at all  latitudes outside the tropics. By 1991, the depletion over North America  averaged nearly 5 percent. 2/ Since 1991, ozone depletion  has further intensified. 3/ RUSH FICTION: "Mount Pinatubo in the Philippines spewed forth more than a  thousand times the amount of ozone-depleting chemicals in one  eruption than all the fluorocarbons manufactured by wicked,  diabolical, and insensitive corporations in history. . . . Conclusion:   mankind can't possibly equal the output of even one eruption from  Pinatubo, much less billion years' worth, so how can we destroy ozone?" 4/ SCIENTIFIC FACT:  Limbaugh's numbers are completely off-base. Volcanoes emit two  sorts of ozone-depleting compounds.  One is hydrochloric acid, but  the amount of this chemical in the stratosphere, measured before  and after Pinatubo's eruption in 1991, was found to be largely unchanged. 5/   The other ozone-depleting chemical emitted by Pinatubo, sulfur  dioxide, is converted in the stratosphere into tiny particles which,  acting in combination with man-made chlorofluorocarbons (CFC's),  temporarily increased the rate of ozone depletion by several  percentage points during 1992 and 1993. 6/  Nevertheless, nearly  all the particles resulting from the Mt. Pinatubo eruption have  already washed out of the atmosphere, unlike CFC's, which remain  in the stratosphere for as long as a century. 7/ Cumulatively speaking, Pinatubo's destructive effect on the ozone  layer has been about fifty times less than that of CFC's, rather than  a thousand times greater, as Limbaugh claims.  Thus, his estimate  is off by a factor of fifty thousand. RUSH FICTION: What "environmental wackos . . . really want to do is attack our way   of life" in the effort to limit CFC's.  "Their primary enemy:  capitalism."  8/ SCIENTIFIC FACT: Limbaugh ignores the fact that the conservative Reagan administration  signed onto the Montreal Protocol, the international agreement to  restrict CFC's, and that crucial support for the measure came  from some of the largest manufacturers of these chemicals,  who, like Ronald Reagan, are hardly enemies of capitalism. Although many of these corporations initially resisted action when the  ozone problem was discovered, Dupont, Allied Signal, and  other domestic producers of CFC's have long favored strong  restrictions concerning their production and use. Indeed,  Dupont proposed a global ban of CFC's before European or United States governments did. 9/ RUSH FICTION: "In just one day in January [1992], NASA measured the amount of   chlorine and another gas in the atmosphere of the Northern  Hemisphere and found an unusually high level compared to normal.  There were headlines for days about an ozone hole in the  atmosphere above North America. Senator Al Gore . . . predicted that President Bush would soon  come around on all this because of the 'ozone hole over Kennebunkport,'  despite the fact there was no such thing. . . . Within a few weeks,  it was learned that most of the unusual measurements could be  attributed to Mount Pinatubo's eruption, a fact the agenda-oriented  scientific community attempted to ignore." 10/ SCIENTIFIC FACT: Limbaugh's last statement is absolutely false. The measurements to which he  refers, of extremely high levels of chlorine monoxide, were made by NASA  only six months after Pinatubo's eruption and in a particular region of  the Arctic stratosphere that was at the time unaffected by the volcanic  emissions.  Furthermore, large amounts of these chemicals were  measured throughout the month of January, not just on one day, as  Limbaugh asserts. 11/  As for the rest, the condition of the ozone  layer in January of 1992 was a great deal more complex than  Limbaugh's account would suggest.  Indeed, many scientists  were disturbed by the high chlorine monoxide levels. For a very large depletion to occur, however, the Arctic stratosphere  would have had to remain cold for several more weeks, as it often  does that time of year. Instead, a sudden warming occurred the  following month, so the damage to the ozone layer never became  as severe as originally feared. If it had, the depletion might well have reached 20 to 30 percent in the lower stratosphere,  rather than the 10 to 15 percent that was recorded. Indeed, such  large depletions could occur over parts of Northern Europe and  Canada during any winter, and may do so in the future. 12/ In his most recent book, See, I Told You So, Limbaugh returns to  the subject of ozone depletion. This time, he discusses the  implications of a possible prehistoric supernova that may have d amaged the atmosphere: RUSH FICTION: "Scientists say a supernova 340,000 years ago disrupted 10  percent to 20 percent of the ozone layer, causing sunburn in  prehistoric man.  Wait a minute - I thought only man could  destroy the ozone. . . . And if prehistoric man merely got a  sunburn, how is it that we are going to destroy the ozone layer  with our air conditioners and underarm deodorants and cause  everybody to get cancer? Obviously we're not...and we  can't ...and it's a hoax." 13/ SCIENTIFIC FACT: The report of a prehistoric supernova exploding close enough to the  Earth to have possibly affected its ozone layer, thousands of years  ago, though of doubtful relevance to Limbaugh's argument, was  published in the British journal Nature and followed up by the New  York Times in 1993. As quoted in the Times, Dr. Neil Gehrels, one  of the authors of the report, clearly did not mean to minimize the  possibility that the ozone loss that may have resulted would have  damaged whatever forms of life were roaming the planet. Indeed, he was reported as saying that the effects of such an ozone  depletion may well "have impaired the health of human beings and  other creatures..." 14/ RUSH FICTION: "Even The Washington Post - that haven of liberal mythology - published  a front-page story on April 15, 1993, that dismissed most  of the fears about the so-called ozone hole... had this to  say: 'In fact, researchers say the problem appears to be heading  toward solution before they can find any solid evidence that  serious harm was or is being done.'" 15/ SCIENTIFIC FACT: Limbaugh neglects to mention that the problem of ozone depletion  appears to be heading towards solution only as a result of international  agreements to restrict the production and use of CFC's. Thanks to  these agreements, the ozone layer should return to near-normal levels  around the year 2045.  Before 1998, however, stratospheric ozone is  expected to become thinner every year, and the amount of ultraviolet  radiation reaching the Earth to increase, assuming other influences  remain constant. 16/ Although the consequences of increased ultraviolet exposure for  plants and marine life are just beginning to be explored, the  damage to humans from long-term exposure is well known. In many parts of the globe, ozone depletion is likely to cause a  rise in rates of skin cancer, particularly non-melanoma  cancers, which, due to lifestyle factors, are already at record levels. 17/ RUSH FICTION:  "A few days later, the authoritative journal Science published a story headlined 'Ozone  Takes Nose Dive After the Eruption of Mt. Pinatubo.' It pointed out that the ozone l ayer should show significant signs of recovery by 1994. But have you heard Algore  (sic) or any other ozone alarmist step up and admit that he or she  perpetuated (sic) a fraud on the American people?" 18/ SCIENTIFIC FACT: Indeed, the ozone layer did not thin as much in 1994 as it did in 1993, due to  the washing out of emissions from Mount Pinatubo (see above).&nbs; Nevertheless,  as Science magazine pointed out in a recent issue, this improvement is only  temporary, since levels of "atmospheric chlorine will continue to increase  until controls on CFC emissions take hold late in this decade.  Pinatubo or no, things will get worse." 19/ Global Warming and the Greenhouse Effect Global warming is another topic about which Limbaugh attempts to  mislead his readers, despite the international scientific consensus  on many aspects of this issue.  This consensus is reflected in  the findings of the top researchers in the field, as published  in the peer- reviewed scientific literature, and the  conclusions of the Intergovernmental Panel on Climate Change (IPCC),  the international scientific panel assessing climate change, which  consists of a network of 2,500 experts worldwide. The IPCC has  issued two reports clearly stating and then reaffirming that the  Earth's climate will warm due to the buildup of man-made greenhouse gases. 20/ In 1992, the National Academy of Sciences published its own report,  concluding that "greenhouse warming poses a potential threat sufficient  to merit prompt responses." 21/ Instead of taking on the international scientific community directly,  however, Limbaugh chooses to attack Vice-President Al Gore, and his book Earth in the Balance. RUSH FICTION: "Algore's (sic) book is full of calculated disinformation.  For instance, he claims that 98 percent of scientists  believe global warming is taking place.  However a Gallup poll of scientists involved in global climate  research shows that 53 percent do not believe that global  warming has occurred, 30 percent say they don't know, and only 17  percent are devotees of this dubious theory." 22/ SCIENTIFIC FACT: These numbers, apparently lifted from a George Will syndicated  column of September 3, 1992, 23/ are supposed to reflect the  findings of a Gallup poll taken in late 1991 to ascertain  the opinions of research scientists concerning global  warming. Even though polling is of doubtful relevance  for determining the scientific truth of any proposition,  it should be pointed out that nowhere in the actual  poll results are there figures that resemble those  cited by Will or Limbaugh. Instead, the Gallup poll found that a substantial majority of the  scientists polled, 66 percent, believed that human-induced global  warming was already occurring. Only 10 percent disagreed, and the remainder were undecided. Moreover, the 98 percent figure appears in the context of Al Gore's  book to refer to the percentage of scientists who believe that  human-induced global warming is a legitimate threat, not, as  Limbaugh frames it, to the number of those who argue that it is  already in effect. In fact, the Gallup poll seems to bear out Gore's  estimate as well, finding that only 2 percent of the scientists polled  believed that there was no chance that substantial, human-caused  warming will occur over the next fifty to one hundred years. 24/ RUSH FICTION: "Algore told the Washington Times on May 19, 1993: 'That  increased accumulations of greenhouse gases, particularly CO2,  cause global warming, there is no longer any serious debate.   There are a few naysayers far outside the consensus who try to  dispute that. They are not really taken seriously by the mainstream  scientific community.' Yet we saw in the last chapter that there is  nothing resembling a consensus on this issue among scientists who  have some expertise in this area. In fact, a majority clearly does  not believe global warming has occurred." 25/ SCIENTIFIC FACT: See the preceding item. Furthermore, even the most publicized  and vehement of scientific naysayers, such as Pat Michaels of the  University of Virginia, agree that increased accumulation of carbon  dioxide will eventually cause global warming. What they disagree  about is how much warming will occur over what period of time. 26/ RUSH FICTION: "...back at the time of the first Earth Day, the big concern wasn't  global warming, it was global cooling. . . . the view of          most environmentalists for years after." 27/  SCIENTIFIC FACT: Although the Earth has warmed by about one degree Fahrenheit  over the past hundred years, this warming has not occurred  uniformly.  In particular, during the period from 1940 to  1970, the Northern Hemisphere stopped warming and may have  even cooled slightly. 28/  This hiatus in the long-term trend contributed to   concerns that the Earth was about to cool significantly,   possibly due to the increased amount of soot and other   particulates in the atmosphere. However, warming resumed again in the 1970's and the nine  warmest years on record have all occurred since 1980. 29/ Recent  calculations indicate that the greenhouse effect will outrun the  effects of particulate cooling in the future, although the  accumulation of particulates in the atmosphere may slow the overall  rate of warming. 30/ RUSH FICTION: "A fact you never hear the environmentalist wacko crowd  acknowledge is that 96 percent of the so-called  'greenhouse' gases are not created by man, but by nature." 31/ SCIENTIFIC FACT: This is an obvious straw man set up by Limbaugh. It is true that the  greenhouse effect is, by and large, a natural phenomenon, produced  by gases in the atmosphere such as carbon dioxide and  water vapor that have warmed the Earth for eons, making its  climate moderate enough to support life as we know it. Without  these gases, Earth would be forty to sixty degrees colder,  essentially a frigid desert. 32/ However, in nature these gases usually remain in balance, leading  to a stable climate, while the greenhouse gases added by humans  over the last two hundred years have accumulated to the point that  the amount of carbon dioxide in the atmosphere, for example, is  now more than 25 percent above what it had been for the previous  10,000 years. (Scientists have direct evidence of this data, from  measurements of air bubbles trapped in polar ice cores.) 33/ The  scientific consensus is that the accumulation of carbon dioxide and  other gases due to human activity will alter the climate substantially,  warming the globe by three to eight degrees Fahrenheit over the next century. 34/ Forests and the Spotted Owl One of the most contentious of current political debates  concerns the old-growth forests in the Northwest. Limbaugh  addresses this issue in See, I Told You So by citing mostly  irrelevant statistics on tree growth in the United States as a whole: RUSH FICTION: "Would it surprise you to learn, for instance, that America's forests  are much healthier today in the 1990s than they were at the turn of  the century? In fact, you could say that in the last seventy years  America's forests have been reborn. There are 730 million acres of  forest land in our country today, and the growth on those acres is  denser than at any time. . . . New England has more forested acres  than it did in the mid-1800s. Vermont is twice as forested as it was  then. Almost half of the densely populated northeastern United  States is covered by forest. Why? How could this be? If we are  ravaging our land, as the environmentalists suggest, why are there  more trees around -- more forests?" 35/ SCIENTIFIC FACT: Here, it seems, Limbaugh cannot see the forests for all those trees.   It is true that due to the abandonment of farming, there has been a  regeneration of forests in the northeastern United States over the  past century, although not with all the species they originally contained. Instead, environmentalists' primary concern during the last decade  has been the rampant destruction of old-growth forests, particularly  in the Northwest, where ancient trees were being cut down at an  unprecedented rate, leaving only about 11 to 14 percent of the  original forests still standing. 36/ RUSH FICTION:  "What the environmentalists are saying, in effect, is that some  trees are better than others. Trees that have been planted by man  are not as worthy or valuable as those that grow in 'virgin' forests. What is a virgin forest anyway? Most trees live for only a couple of  hundred years and then die. No tree lives forever." 37/ SCIENTIFIC FACT: Virgin forests are forests untouched by humans. In the  Northwest, they are mostly old-growth forests, featuring towering  stands of trees, 200 to over 1,000 years old. 38/ These trees are  known to harbor a number of endangered or threatened species,  among them (but not limited to) the Northern spotted owl. Which  brings us to Limbaugh's next point: RUSH FICTION: "It reminds me of the researchers who recently ventured into the  forests of California. Do you know what they found? No, not  Algore. They found spotted owls. It seems the place is teeming  with spotted owls - even though they're supposed to be an  endangered species." 39/ SCIENTIFIC FACT: Fewer than two thousand pairs of the Northern spotted owl are  thought to survive in California forests -- a number that could hardly  be described as "teeming". 40/ Even more importantly, at a meeting  of experts called by the U.S. government in December 1993 at Fort  Collins, Colorado, virtually every biologist who presented data  concluded that the total numbers of the owl are still in decline.   Moreover, the population loss rate appears to be accelerating. 41/ On the whole, Limbaugh dealt with this issue more honestly in his  first book, The Way Things Ought to Be, when he asserted, "If the  owl can't adapt to the superiority of humans, screw it. . . ." 42/ Conclusion Although he attacks his opponents in the scientific community  for being driven by ideology, it is Rush Limbaugh who clearly allows  his political biases to distort the truth about a whole range of  important scientific issues. All in all, the words he uses to describe Al Gore's book could more  appropriately be applied to his own. Limbaugh's most recent work,  just like the previous one, is "nothing more than a hysterical,  pseudo-scientific tract designed to cut off calm, reasoned  discussion of environmental issues and simply push the nation  toward irrational, irreversible, misguided (not to mention expensive) public policies." If the words of Rush Limbaugh on scientific  subjects prove anything, it should be "to discredit; from any  serious participation in our nation's debate over the environment." 43/ The American public deserves better: to have its intelligence  respected, not abused.
