NASA Earth Observatory Human activities cause ozone depletion and global warming Ozone O3 depletion does not cause global warming, but both of these environmental problems have a common cause: Global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
Sir Robert Bob Watson played an important role in both cases There are both links and major differences between ozone depletion and global warming and the way the two challenges have been handled.
While in the case of atmospheric ozone depletion, in a situation of high uncertainty and against strong resistance, climate change regulation attempts at the international level such as the Kyoto Protocol have failed to reduce global emissions.
US manufacturer DuPont acted more quickly than their European Ozone depletion and global warming. They pointed out that the goal of the IPCC is to fairly represent the complete range of credible scientific opinion and if possible a consensus view.
Three years later the report made an impact with the assessment of the state of the art in climate research, an assessment of the threat of climate change itself as well as suggestions for clear emissions reduction targets, even though he argues there was no consensus, and attributed the success of the report to strong precautionary action, and that no scientific outsiders or climate change skeptics were involved.
Public opinion on climate change The two atmospheric problems have achieved significantly different levels of understanding by the public, including both the basic science and policy issues.
Americans voluntarily switched away from aerosol sprays before legislation was enforced, while climate change has failed in achieving a broader scientific comprehension and in raising comparable concern.
This was not the case with global warming. Sheldon Ungar, a Canadian sociologist, assumes that while the quantity of specialized knowledge is exploding, in contrast scientific ignorance among lay people is the norm and even increasing.
Public opinion failed to tie climate change to concrete events which could be used as a threshold or beacon to signify immediate danger.
The scientific assessment of the ozone problem also had large uncertainties; both the ozone content of the upper atmosphere and its depletion are complicated to measure and the link between ozone depletion and rates of enhanced skin cancer is rather weak.
But the metaphors used in the discussion ozone shield, ozone hole resonated better with lay people and their concerns. It is these pre-scientific bridging metaphors built around the penetration of a deteriorating shield that render the ozone problem relatively simple.
That the ozone threat can be linked with Darth Vader means that it is encompassed in common sense understandings that are deeply ingrained and widely shared. The fate of celebrities like President Ronald Reaganwho had skin cancer removal from his nose in andwas also of high importance.
Economics of global warming Cass Sunstein and others have compared the differing approach of the United States to the Montreal Protocol, which it accepted, and the Kyoto Protocol, which it rejected. A citizen boycott of spray cans gained importance in parallel. The EU shifted its position after Germany, which also has a large chemical industry, gave up its defence of the CFC industry  and started supporting moves towards regulation.
In the case of Kyoto, then secretary of the environment Angela Merkelprevented a possible failure by suggesting to use as starting date for emission reduction.
In so far the demise of the Eastern European heavy industry allowed for a high commitment, but actual emissions kept on growing on a global scale.Ozone depletion and climate change, or Ozone hole and global warming in more popular terms, are environmental challenges whose connections have been explored and which have been compared and contrasted, for example in terms of global regulation, in various studies and books.
Apr 14, · One of the most common mistakes that we have observed in discussions of climate and atmospheric change is confusion between the rather separate concepts of ozone depletion and global warming. Ozone Depletion vs Global Warming.
In the layman’s approach, ozone depletion and global warming is mostly the same thing.
However from a more detailed look at the two issues, it is clearly evident that both of them mean absolutely two different things.
Climate Ozone Depletion Today, there is widespread concern that the ozone layer is deteriorating due to the release of pollution containing the chemicals chlorine and bromine. Ozone Depletion & Global Warming.
Instead of looking back at the successful CFC phaseout, the U.S. needs to be looking toward the future and working to rapidly phase out all ozone depleting substances without compromising the goals of other treaties. Research geophysicist, Dr. Peter L. Ward discusses the impact of CFC gases on ozone depletion just in time for Earth Day, Sunday April Ozone Depletion, Not Greenhouse Gases Cause for Global Warming, Says Researcher.
