Climate Change: A peer-reviewed study by a respected Canadian physicist blames the interplay of cosmic rays and chlorofluorocarbons for 20th-century warming. The CFCs are now gone, and so is warming — perhaps for the next 50 years. Much of the nation got a white Christmas this year, some in unprecedented quantities. A record-breaking storm deposited 12 to 30 inches of snow in Virginia, Maryland and Washington, D.C. Many places set records for the most snow in a single December day as more than 50% of the U.S. was covered by the white stuff. Scientists (and here we use the word...

The National Aeronautics and Space Administration, better known as NASA, said in July that it had found the "smoking gun" that caused the space shuttle Columbia to break apart as it re-entered the Earth's atmosphere on Feb. 1: a piece of foam that had peeled off the external fuel tank and struck the shuttle's wing 1 minute and 22 seconds after liftoff. But many experts looking at the tragedy that killed seven astronauts say there is a deeper cause. They say that the metaphorical smoking gun should be painted green. Because of demands that the agency help to front for...

THE green movement’s greatest triumph – the abolition of ozone-destroying CFC gases in the 1980s – may become its biggest embarrassment because of research showing that their replacements are sharply accelerating global warming. CFC, or chlorofluorocarbon, gases were widely deployed in air-conditioning and refrigeration units before they were found to destroy the ozone layer and banned under the 1987 Montreal protocol. They were replaced by HFCs – hydrofluorocarbons – gases that have far less effect on ozone but have since been revealed as extremely powerful greenhouse gases. A ton of HFC23 used in refrigeration has the same global warming potential...

The following petition has 2,200 signatures. Also please file any complaints with the FDA (Medwatch Reporting Form). Here is the link. https://www.accessdata.fda.gov/scripts/medwatch/medwatch-online.htm Find the blue Begin button to the right to start. Text of petition: The FDA, in compliance with the Montreal Protocol, has banned the use of life-saving CFC propellant albuterol asthma rescue inhalers in order to help restore the ozone layer, even though it has been widely acknowledged that these CFC inhaler emissions are too trivial to harm the ozone layer: Leslie Hendeles, University of Florida Professor of Pharmacy and Pediatrics, has noted that CFC inhalers release negligible...

WATERLOO, Ont. (Tuesday, Sept. 16, 2008) -- A University of Waterloo scientist says that cosmic rays are a key cause for expanding the hole in the ozone layer over the South Pole -- and predicts the largest ozone hole will occur in one or two weeks. Qing-Bin Lu, a professor of physics and astronomy who studies ozone depletion, said that it was generally accepted for more than two decades that the Earth's ozone layer is depleted by chlorine atoms produced by sunlight-induced destruction of chlorofluorocarbons (CFCs) in the atmosphere. But more and more evidence now points to a new theory...

A federal ban on ozone-depleting chlorofluorocarbons (CFCs), to conform to the Clean Air Act, is, ironically, affecting 22.9 million people in the United States who suffer from asthma, says Scientific American. Generic inhaled albuterol -- the most commonly prescribed short-acting asthma medication that requires CFCs to propel it into the lungs -- will no longer be legally sold after December 21, 2008. As more patients see their prescriptions change and costs go up -- the reformulated brand-name alternatives can be three times as expensive, raising the cost to about $40 per inhaler -- many question why this ban must begin...

Eco-terrorists have struck again. Not in the dead of night, to be pursued by diligent agents of the FBI, but right out in the open, in a public meeting, under the auspices of the U.S. Food and Drug Administration (FDA). On January 24, one of those ubiquitous FDA panels of "outside experts" voted, by an 11 to seven margin, to recommend that FDA ban non-prescription, over-the-counter asthma inhalers, used routinely by millions of asthma-sufferers to control the symptoms of their debilitating condition. As frequently noted in the press, while such recommendations are not binding, they are most often adopted. The...

It’s ironic that Andy Crouch referred to the pseudoscience of Darwinism in his article “Environmental Wager” [Christianity Today, August, p. 66]. Some of his comments about global warming are identical to Darwinist claims. He writes that it’s “all-but-unanimous scientific consensus” and there is “no serious disagreement.” Not only are such unrestrained statements red flags in critical thinking, Crouch needs to do a little better research. If he did, he would find that the scientific journals Science and Nature were criticized for censoring research refuting global warming. Such bias was also found in government panels and other groups on climate change....

Portugal facing EU action for lax disposal of ozone-depleting pollutantThe European Commission has launched legal action against Portugal for failing to enforce laws regulating the disposal of old refrigerators and air conditioning units containing ozone-depleting chlorofluorocarbons (CFCs), enviromentalists said Friday. Quercus, a leading Portuguese environmental group, said it received a letter from the EU Environment Commission last month informing the group that Brussels was opening a probe into complaints that Lisbon has not provided sufficient CFC recycling facilities. The group complained to Brussels last year that only 0.5 percent of roughly 500,000 old CFC-containing equipments were disposed of properly in...

Antarctic Ozone Hole Roars BackMeasurements over and near Antarctica show that ozone is decreasing more rapidly this year than in previous years and that the size of the ozone hole is now as large as the all time record size of 28 million sq. km during September 2000. This is in stark contrast to the ozone hole last year when it was the smallest in more than a decade after splitting in two during late September. In recent years, the ozone hole is at or near its maximum size during mid-September, with the maximum sometimes reached in late September....

$573 Million Will Halve Developing Country CFCs ROME, Italy, December 2, 2002 (ENS) - Negotiators from 140 governments have adopted a $573 million funding package to halve the consumption and production in developing countries of chlorofluorocarbons (CFCs), the leading destroyer of the stratospheric ozone layer, by the year 2005. The CFCs will be reduced by 50 percent relative to a baseline of average 1995 to 1997 levels. CFCs have been used since the 1930s in refrigerators and air conditioners. They remain in the atmosphere for decades or even centuries. Exposure to UV-C and to too much UV-B can cause...
