| 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 ... |

Holes in the ozone theory
What the ozone hole tells us about the science of climate change |

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 ... |

| 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 ... |
