  • Report: Ozone Hole Has Shrunk by More Than Four Million Square Kilometers

    In the period from 2000-2015, the hole in the ozone layer shrank by more than 4 million square kilometers—nearly a billion acres—according to a new report in the journal Science. During the 1980s and into the 1990s, news of a massive hole in the ozone layer caused worldwide panic, stoked by everything from rumors of sheep being blinded by increased atmospheric radiation to the fear of a skin cancer pandemic and even comparisons to “AIDS from the sky.” Now scientists at MIT along with others have found that since 2000 the ozone hole has actually shrunk by an area half...

    The Antarctic ozone hole has swelled this month to one of its biggest sizes on record, U.N. and U.S. scientists say, insisting that the Earth-shielding ozone layer remains on track to long-term recovery but saying residents of the southern hemisphere should be on watch for high UV levels in the weeks ahead.

    SAN FRANCISCO — The banning of ozone-depleting chemicals hasn't yet caused detectable improvements in the Antarctic ozone hole, new research suggests. Instead, changes in the South Pole's ozone hole from year-to-year are likely the result of natural variations in wind patterns, researchers said here Wednesday (Dec. 11) in a press conference at the annual meeting of the American Geophysical Union. The findings suggest that measuring the total size of the ozone hole says little about ozone depletion, and that it's misleading to use the hole's extent alone to measure environmental progress.
  • Ozone chemicals ban linked to global warming ‘pause’ (new propaganda)

    A new study suggests that the ban on ozone depleting chemicals may have also impacted the rise in global temperatures. CFC gases were responsible for a massive hole in the ozone layer, but they also had a powerful greenhouse effect. The authors link a ban on their use to a “pause” or slowdown in temperature increases since the mid 1990s. The research is published in the journal Nature Geoscience. The subject of a hiatus or standstill in global temperatures rises since 1998 has been the subject of intense debate among scientists, and it has been used as a key argument...
  • Ozone hole above the Arctic has actually been caused by COLD Weather

    The first ozone hole above the North Pole has been aggravated by extraordinarily cold winter temperatures, say scientists. Cooling of the ozone layer enhances the effect of ozone-destroying substances such as chlorofluorocarbons - CFC. A repeated ozone hole above the Arctic is to be expected, say scientists from the KIT Institute of Meteorology and Climate Research. About a year ago, the scientists detected that ozone degradation above the Arctic for the first time reached an extent comparable to that of the ozone hole above the South Pole. At a level of around 13 miles above the ground, 80 per cent...

    During my enlistment in the Air Force, I was a meteorologist and while stationed here in Alaska, I spent my time as a meteorologist at Elemdorf A.F.B. And when Mt Pinatubo and Mt Redoubt erupted in the early 1990‘s, I personally briefed NASA pilots and provided upper air soundings (Skew-Ts) so they could conduct their missions of collecting ash samples and gas samples. And it is well known that volcanic eruptions and the gases that are present in the eruptions will increase the chlorine concentration in the stratosphere and break down the ozone layer over the arctic.

    Remember the big scare of the 1980s, when we were told that between all the fluorocarbons in products like hairspray and deodorant, a big hole was developing in the Ozone layer and the entire population of the world was about get cancer at the very same time? Good News! After taking fluorocarbons out of our products the holes in the Ozone layer over the Artic and Antarctic are closing. But have no fear the Ozone environmentalists haven't lost their life's mission, they can just become global warming moonbats. A new study claims that by closing the Ozone hole we are...

    WASHINGTON (AFP) – Nitrous oxide emissions caused by human activity have become the largest contributor to ozone depletion and are likely to remain so for the rest of the 21st century, a US study has concluded. The study by the National Oceanographic and Atmospheric Agency said efforts to reduce chlorofluorocarbons (CFCs) in the atmosphere over the past two decades were "an environmental success story. ... Emissions and production of those substances are regulated under the 1987 Montreal Protocol. But the treaty excludes nitrous oxides, which are emitted by agricultural fertilizers, livestock manure, sewage treatment, combustion and certain other industrial processes....

    STOCKHOLM (AFP) – The ozone layer over Sweden was thicker in February than it has been in decades, just a year after the second-thinnest level was recorded, the Swedish meteorological institute SMHI said on Tuesday. Measurements taken at SMHI's station in Norrkoeping, just south of Stockholm, showed the ozone layer was at its thickest in February since recordings there began in 1988, with a measurement of 426 Dobson units (DU). At the Vindeln station in northern Sweden, where measurements began in 1991, a record high of 437 DU was recorded. "We have to go as far back to the measurements...

    PANJIM, JUNE 16 (Agencies) — Manmade chemicals have damaged the ozone layer of the upper atmosphere that shields Earth from the harmful effects of the sun’s ultraviolet rays, each summer creating a hole over the South Pole that expands to nearly the size of Antarctica. But in 1996, an international treaty banned the chemical refrigerants and propellants (known as CFCs, or chlorofluorocarbons), and the hole has been shrinking. Scientists predict it may stop forming by the end of this century. But that’s not necessarily good news. A new study published in ‘Science’ says that the closing of the ozone hole...

There is no hint of a dark side to the blaze of red. But strawberries are a painful subject for Guillermo Ruiz.

    At the UN conference on climate change in Nairobi, which ended last week, the buzz was all about a paper published in August in the journal Climatic Change by Nobel laureate Paul J. Crutzen, of the Max Planck Institute for Chemistry in Germany. Crutzen, one of three scientists sharing the 1995 Nobel in chemistry for their work on the depletion of the ozone layer, suggested that if the sun were to raise the temperature of the Earth dangerously high, an effective countermeasure would be to deliberately shoot sulfites into the stratosphere. Unlike carbon dioxide, which traps heat in the atmosphere,...

  • Earth's formerly thin ozone layer is recovering

    Reuters ^ | August 30, 2006
    Earth's protective ozone layer, which was notably thinning in 1980, may be fully recovered by mid-century, climate scientists said on Wednesday. Ozone in the stratosphere, outside the polar regions, stopped thinning in 1997, the scientists found after analyzing 25 years worth of observations. The ozone layer shields the planet from the sun's harmful ultraviolet radiation, but human-made chemicals -- notably the chlorofluorocarbons found in some refrigerants and aerosol propellants -- depleted this stratospheric ozone, causing the protective layer to get thinner. The scientists said the ozone layer's comeback is due in large part to compliance with an 1987 international agreement...

    WASHINGTON (AFP) - A satellite named Aura will be launched at the weekend to study Earth's weather, NASA (news - web sites) said. Lift-off is scheduled for 10:02 GMT Sunday from Vandenberg airbase in California. The launch was set for mid-June, but was pushed back by various technical problems. Aura will promote understanding of the influence the composition of the atmosphere has on climate change as well as regional differences in air quality. Scientists are also keen to know if the condition of the ozone layer, which protects terrestrial life from harmful radiation, is worsening or healing itself of the...
