But if emissions of CH2Cl2 are held to current levels, healing of the ozone hole would be delayed only 5 years or so, the team finds.
Industrial emissions of a chemical commonly used in solvents, paint removers, and the production of pharmaceuticals have doubled in the past few years, researchers have found, which could slow the healing of the ozone layer over Antarctica anywhere between 5 and 30 years — or even longer if levels continue to rise.
If Lu's suggestion is correct, ozone levels should fall then rise every 11 years, in step with changes in cosmic - ray intensity driven by the 11 - year solar cycle.
«A week ago, the ozone concentration in the stratosphere was still at a normal level; I don't know if it has changed yet.
If these pheromones are similarly broken down in the presence of ozone and nitrogen oxides, this could also seriously hit population levels.
If ground - level ozone exceeds 70 parts per billion, the U.S. Environmental Protection Agency issues an air quality advisory.
Similarly, if the level of ozone could be lowered by just 1 part per billion (ppb) nationwide, about 1,900 lives would be saved each year.
Ozone should recover to its pre-1980 levels by the middle of this century and slightly later for Antarctica where the protective gas layer gets extremely thin between August and December every year, the WMO reportedly said, adding that the process can be speeded up by almost 11 years if existing stocks of ozone - depleting products, such as those found in old refrigerators and fire extinguishers are destrOzone should recover to its pre-1980 levels by the middle of this century and slightly later for Antarctica where the protective gas layer gets extremely thin between August and December every year, the WMO reportedly said, adding that the process can be speeded up by almost 11 years if existing stocks of ozone - depleting products, such as those found in old refrigerators and fire extinguishers are destrozone - depleting products, such as those found in old refrigerators and fire extinguishers are destroyed.
If ozone doesn't return to normal levels, the risk of developing skin cancer and cataracts increases from the increased levels of UV radiation that will reach the Earth.
Does surface level ozone eventually rise up into the stratosphere, and if so, does that affect Earth's ozone balance?
IPCC [26] projects the following trends, if global warming continue to increase, where only trends assigned very high confidence or high confidence are included: (i) increased malnutrition and consequent disorders, including those related to child growth and development, (ii) increased death, disease and injuries from heat waves, floods, storms, fires and droughts, (iii) increased cardio - respiratory morbidity and mortality associated with ground - level ozone.
[Response: Upper atmosphere cooling as a function of increased CO2 occurs at all levels including the mesosphere, implying directly that the mechanism can't rely on the presence if ozone or absorbtion of solar uv.
To 337 (Anonymous Coward): For clarity, we are discussing the explanation that discounts a role for ozone, in which case I argue the atmosphere would warm at every level if CO2 is added.
With such facts, it's worth to note that the proclaimed impending Maunder Minimum, although having little effect on AGW, will have a positive effect on the ozone hole: if the lower level sun activity is confined to essencialy UV spectrum, then ozone will be depleting at lower rate, giving it a chance to recover quicker.
Does surface level ozone eventually rise up into the stratosphere, and if so, does that affect Earth's ozone balance?
If this happens during northern winter, surface pressure falls in the Arctic (rising AO) the night jet stalls, NOx injection falls away, stratospheric ozone levels increase, the coupled circulation is invigorated and pressure falls at 50 - 60 ° north and this is associated with cloud loss (when global cloud cover is at its maximum value) and a strong rise in global sea surface temperature.
As if sweltering heat weren't bad enough, Europeans also suffered through a higher - than - normal number of days with dangerous smog levels that year.6 Smog — with ground - level ozone as the main component — forms when sunlight reacts with chemicals such as volatile organic compounds, carbon monoxide, nitrogen oxides, and water vapor.
IPCC [26] projects the following trends, if global warming continue to increase, where only trends assigned very high confidence or high confidence are included: (i) increased malnutrition and consequent disorders, including those related to child growth and development, (ii) increased death, disease and injuries from heat waves, floods, storms, fires and droughts, (iii) increased cardio - respiratory morbidity and mortality associated with ground - level ozone.
