No Can Do On aerosols	Umbra Fisk	06 Oct 2008	Ask Umbra
Dear Umbra, Love the column. Keep up the great stuff! A question: My co-workers and I are suspicious of buying spray cans, even though we know they no longer contain CFCs. We suspect that aerosol cans contain HCFCs -- hydrochlorofluorocarbons -- which are proving to be dangerous as well, this time as greenhouse gases. Do all aerosol cans contain HCFCs? Can we trust a "green" product like an essential-oils-and-water-based deodorizer that c ...

The Ozone Diet Ozone hole bigger this year than last		16 Sep 2008	News
Posted at 3:58 PM on 16 Sep 2008 Happy International Day for the Preservation of the Ozone Layer! Sad to say, the hole that plagues the ozone is already bigger this year than last, and will likely not max out in size until late September or early October. As of Saturday, the hole measured 10.4 million square miles; last year, at its biggest, it was 9.7 million square miles. While a gash bigger than North America might seem somewhat concerning ...

Tell Costco to stop selling climate crack Compressed air cans are contributing to ozone destruction	JMG	27 Jun 2008	Gristmill
Photo: Jeff Mo There was an interesting post a while ago about the havoc created by compressed air cans -- you know, the ones you use to dust off your keyboard. Who knew that they were full of intensely powerful greenhouse gases? I sure didn't, but thanks to Eric de Place, now I do -- so I make myself insufferable whenever I see someone with one, and I point out how easy it is to just turn the keyboard over and knock the crumbs out. But whenever I see a pallet of ...

A Lung Time Coming Ozone-depleting asthma inhalers being phased out		02 Jun 2008	News
Posted at 10:27 AM on 02 Jun 2008 Asthma inhalers containing ozone-depleting chlorofluorocarbons will be phased out by the end of 2008, the U.S. Food and Drug Administration announced Friday. The phaseout of CFCs is required under the Montreal Protocol, an international treaty that the United States actually deigned to sign on to. Alternatives to CFC inhalers use hydrofluoroalkanem as a propellant; HFA inhalers may taste differe ...

Lethal injections Science: Geo-engineering scheme damages the ozone layer	Joseph Romm	30 May 2008	Gristmill
Science has published a major new study, 'The Sensitivity of Polar Ozone Depletion to Proposed Geoengineering Schemes' ($ub. req'd). The study finds: The large burden of sulfate aerosols injected into the stratosphere by the eruption of Mount Pinatubo in 1991 cooled Earth and enhanced the destruction of polar ozone in the subsequent few years. The continuous injection of sulfur into the stratosphere has been suggested as a 'geoengineering' scheme to counteract global w ...

Time to Move to Mars Are fixing the climate and the ozone layer mutually exclusive?		24 Apr 2008	News
Posted at 3:59 PM on 24 Apr 2008 A geoengineering scheme to solve climate change could hurt the Antarctic ozone layer, while recovery of the ozone hole could increase Antarctic warming, new research suggests. A study published Thursday in Science decries suggestions to solve climate change by spewing sulfur into the atmosphere, saying that such a scheme would wipe out the Arctic ozone layer and delay the healing ...

At Lung Last Smog can kill, says report		22 Apr 2008	News
Posted at 2:57 PM on 22 Apr 2008 Short-term exposure to smog is clearly linked to premature deaths, a National Academy of Sciences report has concluded. Some Bush administration officials have claimed that the link between ground-level ozone and health is, well, hazy: when the U.S. EPA was determining acceptable air standards for ozone last month, officials in the Office of Management and Budget claimed there was "considerable uncertainty" of a ...

Bush Whacked President Bush interfered to weaken U.S. ozone standards		14 Mar 2008	News
Posted at 10:39 AM on 14 Mar 2008 President Bush interfered at the last minute to weaken the recently announced U.S. ozone standards, according to EPA documents. On Wednesday, the EPA set both the "public health" standard (how much ozone is in one place at one time) and the "public welfare" standard (consideration of the long-term effect of ozone) at the same level. Before Bush interfered, the agency planne ...

Gasp! EPA lowers ozone limit, but ignores scientific advisers' calls to lower it more		12 Mar 2008	News
Posted at 3:34 PM on 12 Mar 2008 Photo: iStockphoto In an effort to clear up smog, the U.S. EPA on Wednesday lowered the permissible amount of ozone in the air, a move that will require 345 counties around the country to clamp down on pollution over the coming years. But the agency ignored the calls of its own scientific advisers for a steeper pollution cut. The EPA will lower the ozone standard to 75 parts ...

U.S. Mayors Climate Conference: Gore VI Gore: What we can learn from the ozone hole	David Roberts	02 Nov 2007	Gristmill
Kelly Fergusson, mayor of Menlo Park, Calif. ("investment capital of the world!"), asks: we've overcome huge environmental challenges like DDT and the ozone hole before. What can we learn from those successes? First, Gore causes me to do a double take by saying that his mother used to read to he and his sister from Silent Spring. Jeebus! I guess that explains a lot. However, he knows more about the ozone fight. And boy does he know about it -- here he laun ...

Holes in the ozone theory What the ozone hole tells us about the science of climate change	Andrew Dessler	09 Oct 2007	Gristmill
The atmospheric sciences community is excitedly discussing new results that potentially cast doubt on our understanding of the chemistry of the Antarctic ozone hole. The ozone hole is formed when two molecules of chlorine monoxide react with each other to form what is known as the chlorine dimer, ClOOCl, and that molecule is subsequently blasted apart by sunlight to release the chlorine atoms. New results suggest that this reaction is actually much slower than previo ...

Liar, Liar, Purifier California bans in-home ozone air purifiers		28 Sep 2007	News
Posted at 4:20 PM on 28 Sep 2007 In-home air purifiers that emit more than a tiny amount of ozone will be banned under a new California regulation. While manufacturers of ozone air purifiers claim that their products can relieve asthma and other respiratory symptoms, thousands of studies have shown that ozone exposure can actually worsen such conditions. "There are reports of ozone being generated in someone's living room ... ...

We're Just Going Through a Phaseout Faster phaseout of ozone-damaging chemicals agreed to by 191 nations		24 Sep 2007	News
Posted at 5:51 AM on 24 Sep 2007 At the conference marking the 20th anniversary of the Montreal Protocol last week, some 191 nations agreed to a faster phaseout of ozone-depleting chemicals than had originally been negotiated in 1987. Hydrochlorofluorocarbons, or HCFCs, emerged in the 1990s as a less-ozone-damaging alternative to CFCs, which did truly nasty things to the ozone layer. But HCF ...

Sorry climate, I had to dust my keyboard Why we should ban compressed chemical dusters	Eric de Place	27 Apr 2007	Gristmill
I have an untidy habit of eating while I'm working on my computer. Heck, I'm eating a doughnut while I write this post. Unfortunately, my habit inevitably results in little crumbs of sandwich or potato chips or whatever making their way onto my computer keyboard. Every once in a while I look down at my crumb-ridden keyboard, get disgusted, and embark on a cleaning frenzy. And as many office workers may know, one of the easiest ways to clean a keyboard is with those ...

Damned If ... OK, Just Damned CFC alternatives contribute to global warming When signatories to the 1989 Montreal Protocol phased out ozone-depleting, heat-trapping chlorofluorocarbons (CFCs) in foams and refrigerants, most replaced them with more-ozone-friendly-but-still-heat-trapping hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs). Too bad: HCFCs and HFCs will add the equivalent of 2 billion to 3 billion tons of CO2 t ...

A Patch Made in Heaven Ozone layer is recovering, a little		04 May 2006	Daily Grist
A Patch Made in Heaven Ozone layer is recovering, a little Remember the ozone layer? It's doing better, thanks for asking. A report in Nature indicates that our layer of protection from the sun's ultraviolet rays has stabilized or increased slightly in the past decade. Thanks to human use of ozone-depleting chlorofluorocarbons (CFCs) in aerosols and refrigerants, scientists found in the 1980s that seasonal ozone levels were plunging. The new re ...

Ozoning Out On climate confusion	Umbra Fisk	14 Nov 2005	Ask Umbra
Dear Umbra, Any chance that the most extreme of the peak-oil folks are correct, and that in spite of our thoughtlessness, we just won't have enough oil to totally destroy the ozone layer? Dan Wasson Pittsburgh, Penn. Dearest Dan, Oil has very little to do with the ozone layer, but it does have to do with global warming. Global warming and ozone depletion are, for our daily purposes, two separate issues. They both involve gaseous, human- ...
