Ozone Layer Recovering But Remains Threatened
First time accepted submitter i kan reed writes in with some good news from the ozone report of the United Nations. The Earth’s protective ozone layer is on track to recover by the middle of the century, the United Nations today reported, urging unified action to tackle climate change and curb continued fluctuations to the composition of the atmosphere. That is according to the assessment of 300 scientists in the summary document of the Scientific Assessment of Ozone Depletion 2014, published by the UN Environment Programme (UNEP) and the UN World Meteorological Organization (WMO). “International action on the ozone layer is a major environmental success story,” WMO Secretary-General Michel Jarraud said in a news release. “This should encourage us to display the same level of urgency and unity to tackle the even greater challenge of climate change.”
...it appears that no one has much idea of either the chemistry in the troposphere, or the natural fluctuations which occur.
But the ozone concentration is going up, so we must be doing a great job, mustn't we? Increase the grants...!
Global warming and Bush are still destroying the Ozone.
But if you elect obama for a 3rd , 4th or even 5th term, he will solve it by 2024-2028.
Aren't most propellants for food/human use nitrous oxide? Then the answer would be 0.
Could be, but not for asthma inhalers.
