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 ...

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 ...

They're Just Going Through a Phase Bush administration will propose quicker deadline for phasing out ozone-depleting chemicals		07 Sep 2007	News
Posted at 6:05 PM on 07 Sep 2007 Nearly 200 nations will gather on Sept. 15 to discuss the Montreal Protocol, a 20-year-old treaty put into place to phase out the nasty chemicals that contribute to the thinning of the ozone layer. At the meeting, a dozen countries plan to suggest that participating nations move up the deadline for a full phaseout of refrigerating chemic ...

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 ...

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 ...

Damned If ... OK, Just Damned CFC alternatives contribute to global warming		21 Aug 2006	Daily Grist
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 ...

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 ...

Bubblicious Scientists Consider Funky Plans to Avert Climate Change		20 Jan 2004	Daily Grist
Bubblicious Scientists Consider Funky Plans to Avert Climate Change Plans to slow global warming once dismissed as, well, loopy need to be taken seriously, concluded scientists at a conference on climate change in Cambridge, U.K. The proposed schemes can be divided into two families -- they aim either to capture greenhouse gases such as carbon dioxide to prevent their buildup in the atmosphere, or to shield the plan ...

Stow It		25 Jun 2003	Daily Grist
Stow It The U.S. famously declined to sign the Kyoto Protocol on climate change, but yesterday it jumped on the bandwagon of another effort to control global warming: a research program dedicated to exploring technologies for capturing and storing carbon dioxide. Such technologies, collectively known as carbon sequestration, seek to keep CO2 out of the atmosphere through storage innovations, rather than through lim ...

Giving Us Tropopause The tropopause has risen by an average of 650 feet globally in the last 22 years because of global warming and ozone depletion, according to a study published in the latest issue of the Journal of Geophysical Research. For those of you who've forgotten your junior high school science, the tropopause is the atmospheric layer above the troposphere (which swaddles the Earth) and below the stratosphere (where commercial jets ...
