Ozone at lower latitudes is not recovering, despite Antarctic ozone hole healing
From IMPERIAL COLLEGE LONDON The ozone layer – which protects us from harmful ultraviolet radiation – is recovering at the poles, but unexpected decreases in part of the atmosphere may be…
NASA Claim: Definitive Evidence of the Montreal Protocol’s Success on ‘Ozone Hole’ – but may be premature
From the “Montreal Protocol success is not weather, unless it is” department and NASA Goddard: Using measurements from NASA’s Aura satellite, scientists studied chlorine within the Antarctic ozone hole over…
The Profound and Dominant Impact of Atmospheric Water Vapor upon Ozone Destruction
Guest essay by Michael Wallace, Hydrologist The prevailing model of seasonal and long term global ozone depletion is grounded in a principal assertion that emissions of industrial refrigerants and propellants…
Earth’s ‘ozone hole’ shrinks to lowest since 1988
From NASA Goddard: Warm Air Helped Make 2017 Ozone Hole Smallest Since 1988 Measurements from satellites this year showed the hole in Earth’s ozone layer that forms over Antarctica each…
Ozone treaty taking a bite out of US greenhouse gas emissions
Public Release: 14-Aug-2017 American Geophysical Union From Eurekalert WASHINGTON D.C. — The Montreal Protocol, the international treaty adopted to restore Earth’s protective ozone layer in 1989, has significantly reduced emissions…
Study: trees in cities actually make pollution worse during heat waves
From the AMERICAN CHEMICAL SOCIETY comes this counter-intuitive finding: During heat waves, urban trees can increase ground-level ozone Planting trees is a popular strategy to help make cities “greener,” both…
Claim: 'The blob' in the Pacific boosted Western US ozone levels
From the UNIVERSITY OF WASHINGTON ‘The blob’ of abnormal conditions boosted Western US ozone levels An unusually warm patch of seawater off the West Coast in late 2014 and 2015,…
Claim: forget CO2, it's the Methane and CFC's that will drown us in the ocean
From the “it’s that Methane and Ozone Emergency again” department, comes this breathless headline, for a kitchen sink press release that even includes the obligatory faux sinking atoll of Tuvalu. I…
Newly discovered EPA report says ozone measurements may be way off – cities may be in compliance
EPA Surface Ozone Readings are Inflated by Mercury Vapor – The EPA has known about positive biases caused by mercury vapor since 1999 Guest essay by Forrest M. Mims III Accurate…
Salvaging the Unsalvageable: HFCs and the UN Climate Change Fiasco
Guest opinion: Dr. Tim Ball “Oh what a tangled web we weave, when first we practise to deceive!” Sir Walter Scott (1771-1832) Support for the global warming/climate change agenda is…
Interesting climate sensitivity analysis: Do variations in CO2 actually cause significant global warming?
Guest essay by David Bennett Laing In 1900, Knut Ångström concluded from a famous experiment that very little warming results from a doubling of atmospheric CO2. Although no similar experiment has…
Study: Antarctica has a 'pause' in warming – may be linked to ozone hole stabilization
From the Steig et al. is still dead department: The rapid warming of the Antarctic Peninsula, which occurred from the early-1950s to the late 1990s, has paused. Stabilisation of the…
Scientists claim they have observed first signs of healing in the Antarctic ozone layer
New research has identified clear signs that the hole in the Antarctic ozone layer is beginning to close. Scientists from the University of Leeds were part of an international team…
Volcanoes and Ozone: Their Interactive Effect on Climate Change
Guest essay by David Bennett Laing, Asst. Prof.of Geology, Univ. of Maine (retired) Two different styles of volcanic eruption appear to have been the principal determinants of climate change throughout…
The Ozone Scare Was A Dry Run For The Global Warming Scare
Guest Opinion: Dr. Tim Ball My grandmother told me “Your sins will find you out.” I don’t know if it’s original, but it certainly seems true when you look at…
Ozone hole worse than in recent years – due to colder than normal stratosphere in Antarctica
A couple of days ago we ran a piece at WUWT: Did We Really Save the Ozone Layer? In light of this press release, the question is worth pondering again. From the…
Atmospheric concentration of an ozone destroying chemical drops mysteriously
From the “possible measurement error” department. Larry O’Hanlon (via AGU blogs) writes: Something strange has happened to the atmospheric concentration of a newly discovered, human-made, ozone-destroying gas: it has suddenly…
New Ozone Regulations Will Save Lots of Imaginary People
Guest essay by Charles Battig Now I can finally relax, take a deep breath, and breathe easier. The Environmental Protection Agency, an aggressive arm of the nanny government, has just…
Is Ozone Recovery Warming the Stratosphere – And Adding Credence to Solar Variability?
Guest essay by Steven Capozzola Even though declining ozone cooled the stratosphere in the 20th Century, the IPCC says this cooling proves solar variability doesn’t impact surface temperatures. The climate…
