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 ...

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 ...

Sweet XVI Pope lauds Montreal Protocol, Vatican aims for carbon neutrality		17 Sep 2007	News
Posted at 5:18 PM on 17 Sep 2007 The Montreal Protocol turned 20 this weekend -- and you forgot to get it a gift, didn't you. As nearly 200 nations convene this week to discuss the protocol, which has been successful in spurring an international phaseout of ozone-depleting chemicals, it has been lauded by no less a person than Pope Benedict XVI, who declared on Sunday, "In the last two decades, thanks to an exemplar ...

Pay No Attention to That Protocol Behind the Curtain Twenty-year-old Montreal Protocol has helped combat global warming		07 Mar 2007	Daily Grist
Pay No Attention to That Protocol Behind the Curtain Twenty-year-old Montreal Protocol has helped combat global warming It kind of sucks to be the Montreal Protocol. Not only do you lack the name recognition of your compatriot from Kyoto, you also go widely unrecognized for the work you've done to fight global warming. The phaseout of chemicals called chlorofluorocarbons under the Montreal treaty -- negotia ...

Standing on Protocol U.S. requests exemption from ban on ozone-depleting pesticide, again At a meeting in New Delhi this week, thumb firmly attached to nose, the U.S. is seeking to convince fellow signers of an international ozone-layer treaty that it should be allowed to continue to use and produce a pesticide it had agreed to ban by 2005. With a stockpile of nearly 11,000 tons of methyl bromide -- which not only deple ...

The Hole Truth and Nothing But the Truth Ozone hole biggest, deepest on record		20 Oct 2006	Daily Grist
The Hole Truth and Nothing But the Truth Ozone hole biggest, deepest on record This year's ozone hole is bigger and deeper than any other on record, NASA scientists said yesterday. From Sept. 21 to Sept. 30, the ozone hole sprawled to an average of 10.6 million square miles. That's pretty big, alright: approximately the surface area of North America plus Argentina. In the same September time period, ozone was "virtually gone" in the a ...

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 ...

Holey Moly Antarctic ozone hole may persist 20 years longer than expected		07 Dec 2005	Daily Grist
Holey Moly Antarctic ozone hole may persist 20 years longer than expected Remember that hole in the ozone over Antarctica? The one we fixed? Big environmental success story? Turns out it may take roughly two decades longer than expected for it to fully heal -- until around 2065, instead of 2040 to 2050 -- because sizable amounts of chlorofluorocarbons are still being released into the atmosphere by industrialized nations. Researche ...

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- ...

A Bit of the Old Ultraviolet On UV ratings	Umbra Fisk	14 Oct 2004	Ask Umbra
Dear Umbra, Our radio station provides daily information regarding ultraviolet ratings. I am curious about what these ratings actually represent, and why they change so dramatically. For example, for the past few years, most ratings have been between three and seven. Now we are getting ratings of 10. I doubt the ratings are directly related to Dobson units, which measure the amount of atmospheric ozone present, because they ...

Fed Up Northeast Efforts to Reduce Greenhouse Gases Thwarted by Feds		15 Mar 2004	Daily Grist
Fed Up Northeast Efforts to Reduce Greenhouse Gases Thwarted by Feds Efforts by U.S. states in the northeast to reduce greenhouse gas emissions are falling short, in part due to unsympathetic federal policies. While they see plenty of room for more aggressive efforts, even the region's most vocal environmental critics acknowledge that northeastern states have taken unprecedented steps to reduce emissio ...
