A benefit of 'climate change' – reduced ozone pollutants in coastal cities
University of Houston researchers: Climate change helped to reduce ozone levels – Houston findings should hold for coastal regions around the world Researchers at the University of Houston have determined…
Laughable AGU Claim: 2011 Tōhoku earthquake and tsunami 'spurred global warming'
From the “everything causes global warming” department….except, the effect they are claiming is miniscule compared to business as usual emissions in the USA. For example, they say in the PR:…
New research highlights the key role of ozone in climate change
From the University of Cambridge Many of the complex computer models which are used to predict climate change could be missing an important ozone ‘feedback’ factor in their calculations of…
2014 Antarctic Ozone Hole Holds Steady
From NASA: The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). The size of…
Is the atmospheric ozone recovery real, or just for scoring political points?
To coincide with the upcoming “World Ozone Day 2014″ declared by the U.N. for September 16th, we have some “feel good” news coming out on the 25th anniversary of the…
Ooops – According to NASA, ozone destroying CCl4 remains in atmosphere, and continues to be emitted
NASA research shows Earth’s atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an unknown source decades after the compound was banned worldwide. Carbon tetrachloride (CCl4), which was…
There must be a Paul Ehrlich week in climate science
Yesterday, in Climactic headline shifts the hype factor between two headlines on crop production and climate was pointed out, noting that there was just a small increase in risk. Today…
Claim: Climate change may worsen summertime ozone pollution
From the National Science Foundation: Americans face 70 percent increase in unhealthy ozone levels by 2050 Ozone pollution across the continental U.S. will become worse as global temperatures rise. Credit…
Claim: Climate change threatens to worsen U.S. ozone pollution
From UCAR: BOULDER—Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by the National Center…
Good news: no 'ozone hole' in the Arctic
From the Massachusetts Institute of Technology Plugging an ozone hole MIT researchers find that the extremes in Antarctic ozone holes have not been matched in the Arctic CAMBRIDGE, Mass– Since…
Mysterious new man-made gases pose threat to ozone layer…
Image Credits: NOAA – National Weather Service – Climate Prediction Center By WUWT Regular “Just The Facts” On the heels of Andrew Dessler’s Ozone Hole tweet, we have from the…
Claim: What would have happened to the ozone layer if chlorofluorocarbons (CFCs) had not been regulated?
A new modeling based paper in Atmospheric Chemistry and Physics takes on that question directly. Of course the result is another “saved the world” moment according to some: [ Source:…
Asian ozone pollutes Hawaii and USA west coast – varies with climatic shifts
Asian ozone pollution in Hawaii is tied to climate variability (Nature Geoscience) By Joanne Curcio, Program in Atmospheric and Oceanic Sciences Air pollution from Asia has been rising for several…
At AGU, NASA says CFC reduction is not shrinking the ozone hole – yet
NASA Reveals New Results From Inside the Ozone Hole – Dec. 11, 2013 NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and…
Busted messaging: CFC's cause warming AND cooling
From the make up your freaking minds department comes this oopsy juxtaposition of alarmist messaging. In an attempt to explain “the pause”, researchers are now grasping for explanations: Human actions…
'Ozone hole' may be a warming factor due to wind shifts
First, a clarification; while the AGU calls it an “ozone hole”, it technically isn’t. As NASA says here, it really isn’t a “hole” in the true sense of the word,…
Study says global warming caused by CFCs interacting with cosmic rays, not carbon dioxide
From the University of Waterloo, an extraordinary claim. While plausible, due to the fact that CFC’s have very high GWP numbers, their atmospheric concentrations compared to CO2 are quite low,…
Who would have guessed it? Sunlit snow key to Arctic ozone depletion
I like this study from the NSF, because they did hands-on empirical measurements and experiments to make the determination – Anthony Sunlit Snow Triggers Atmospheric Cleaning, Ozone Depletion in the…
Ozone hole in Antarctica shrinks significantly, but not a record low as erroneously reported elsewhere
While this is good news any way you look at it, I note there are a number of news reports saying that the “Ozone Hole Shrinks to Record Low” which…
