The theories on the ozone layers depletion

New scientific evidence continues to demonstrate that the ozone depletion models -and the resulting ban on CFCs- are based on a Big Lie By Rogelio Maduro Co-author of the book " The Holes in the Ozone Scare"New satellite ozone data and other atmospheric studies based on actual measurements confirm that the ozone layer is not a homogeneous, flat and that atmospheric dynamics, not chemistry, is the driving factor that determines the thickness of the ozone layer. The scientific research reported here strips any shred of credibility from the claims of the ozone depletion theorists leaving the Montreal Protocol backed only by the Malthusian ideotogy of its founders. The dramatic new satellite ozone data, featured on the cover, are from the Crista-Spas ensemble of instruments, designed by scientists at the University of Wuppertal in Germany, which was deployed by the Space Shuttle in November

The theories on the ozone layers depletion

By Jeffrey Masters, Ph. They warned that the loss of ozone would significantly increase the amount of skin-damaging ultraviolet UV-B light reaching the surface, greatly increasing skin cancer and cataracts. The loss of stratospheric ozone could also significantly cool the stratosphere, potentially causing destructive climate change.

Although no stratospheric ozone loss had been observed yet, CFCs should be banned, they said. Critics and skeptics--primarily industry spokespeople and scientists from conservative think tanks--immediately attacked the theory.

Techniques of the Skeptics

However, the stunning discovery of the Antarctic ozone hole in proved the skeptics wrong. In fact, the ozone depletion was far worse than Molina and Roland had predicted. Despite the continued opposition of many of the skeptics, the Montreal Protocol, an international agreement to phase out ozone-destroying chemicals, was hurriedly approved in to address the threat.

Molina and Rowland were awarded the Nobel Prize in The citation from the Nobel committee credited them with helping to deliver the Earth from a potential environmental disaster. On this 30th anniversary of the beginning of the ozone depletion debate, it is revealing to review the techniques the skeptics used in the CFC-ozone depletion issue over the past 30 years.

The Ozone Depletion Theory

All of them have parallels in the current global warming debate. Techniques of the Skeptics Launch a public relations campaign disputing the evidence. Chairman Scorer of DuPont commented that the ozone depletion theory was "a science fiction tale The aerosol industry also launched a PR blitz, issuing a press release stating that the ozone destruction by CFCs was a theory, and not fact.

The symbol of Chicken Little claiming that "The sky is falling! Predict dire economic consequences, and ignore the cost benefits.

The Association of European Chemical Companies warned that CFC regulation might lead to "redesign and re-equipping of large sectors of vital industry However, the economic reality has been less dire.

The alternative technologies already adopted have been effective and inexpensive enough that consumers have not yet felt any noticeable impacts except for an increase in automobile air conditioning service costs " UNEP, These savings came from decreased UV light exposure to aquatic ecosystems, plants, forests, crops, plastics, paints and other outdoor building materials, and did not include the savings due to decreased health care costs.

The report concluded that because of the Montreal Protocol, there would be Find and pay a respected scientist to argue persuasively against the threat.

Scorer blasted Molina and Rowland, calling them "doomsayers", and remarking, "The only thing that has been accumulated so far is a number of theories. But he has never published any scientific papers on the subject.

Articles published in traditional scientific journals undergo a process essential to good science--peer-review. The peer-review process starts when a prospective author submits their work to a journal. The editor of the journal reviews the article, and sends copies to three scientists who are experts in the field.

These anonymous reviewers send their comments on errors that need correcting, omissions that need addressing, etc, back to the journal editor, who then asks the author to submit a revised article addressing the concerns of the reviewers.

After making revisions, the author submits the article back to the journal editor, who can then accept the article, reject it, or send it back for another round of review. The rigors of peer-review are such that a large percentage of submitted articles never get published in the scientific literature.

Inthe year Molina and Rowland were awarded the Nobel Prize in Chemistry for their discovery of the CFC-ozone depletion link, the House Science Subcommittee on Energy and the Environment began a series of hearings to revisit the issue of ozone depletion, where the issue of peer-review was brought up.

During the hearings, Representative John Doolittle, a California Republican, stated, "My own belief, is that the question is still very much open to debate Theories or speculation about this are not sufficient.

We need science, not pseudo-science. Case Study 1 -- Stratospheric Ozone: Myth and Realities", th Congress, 1st session, September 20,Report no.

I found extremely misleading representations by the government and government officials that are not founded on sound science.

What good science did you rely on? I do not have that burden. Elizabeth Whelan to support his criticism of peer-reviewed science. But according to the Columbia Journalism Review, Dr. Unfortunately, our House Majority Leader is not the only one who relies on Dr.

Fred Singer, the expert whom Representative Doolittle referred to, has testified before Congress numerous times, and is probably the most widely quoted skeptic on the ozone hole and global warming issues.

Singer cannot be considered an active scientist publishing in the peer-reviewed literature, or even an objective informed critic.The ozone layer has historically protected the Earth from the harmful UV rays, although in recent decades this protection has diminished due to stratospheric ozone depletion.

Figure \(\PageIndex{1}\): These images from the Total Ozone Mapping Spectrometer (TOMS) show the progressive depletion of ozone over Antarctica from to This "ozone hole" has extended to cover an area as large as . The Skeptics vs. the Ozone Hole.

could cause serious harm to Earth's protective ozone layer (Molina and Rowland, ). Chairman Scorer of DuPont commented that the ozone depletion theory. Reduced ozone levels as a result of ozone depletion ozone depletionA chemical destruction of the stratospheric ozone layer beyond natural reactions.

Stratospheric ozone is constantly being created and destroyed through natural cycles. Various ozone-depleting substances (ODS), however, accelerate the destruction processes, resulting in lower than normal ozone levels.

The Ozone Depletion Theory The theory that man-made CFCs would deplete the ozone layer is one of many theories claiming that ozone depletion would lead to doomsday. The theory originated in March , when James McDonald, an atmospheric physicist from the University of Arizona, testified at congressional hearings of the Super-Sonic Transport (SST) program.

The theories on the ozone layers depletion

Effect of ozone depletion on environment. Ozone layer depletion leads to decrease in ozone in the stratosphere and increase in ozone present in the lower atmosphere. Presence of ozone in the lower atmosphere is considered as a pollutant and a greenhouse gas.

Ozone in the lower atmosphere contributes to global warming and climate change. Apr 26,  · Ozone layer depletion, is simply the wearing out (reduction) of the amount of ozone in the stratosphere.

Unlike pollution, which has many types and causes, Ozone depletion has been pinned down to one major human activity.
