Climate Change Impacts Linked to Ozone Depletion

Increase in storm intensity and frequency could cause further ozone depletion over the U.S.

Climate-driven summer thunderstorms might inject more water into the stratosphere, which has the potential to damage the protective ozone layer over the United States and possibly other parts of the globe.

"A warming world with violent storms holds many unpleasant surprises," said Durwood Zaelke, President of the Institute for Governance and Sustainable Development (IGSD). "Recent research now suggests that this may include damage to the protective ozone shield, which protects us from harmful ultraviolet radiation that causes skin cancer, cataracts, suppresses the human immune system, and damages crops and ecosystems."

“Protecting the stratospheric ozone layer is a job that the Montreal Protocol has done for the last 25 years, putting the ozone layer on a course of recovery by mid-century,” Zaelke continued.

The new challenge is the surprise finding in a recently published Harvard University study that increasing climate-driven summer thunderstorms might inject more water into the stratosphere, which has the potential to damage the protective ozone layer over the United States and possibly other parts of the globe. This study is one of the first to hypothesize that climate change could reduce stratospheric ozone over populated areas. If they prove correct, depletion of the ozone layer will increase if global warming leads to more such storms.

In the stratosphere when temperatures are very low, increasing water vapor releases chlorine residing in inactive forms, mimicking processes that cause the ‘ozone hole’ over Antarctica. While ozone depletion from storms in midlatitude regions like the U.S. has not been reported so far, the study concludes that if the intensity and frequency of the convective injecting storms were to increase as a result of climate change, increased risk of ozone depletion and associated increases in ultraviolet exposure could follow. To confirm and quantify the risk, more detailed modeling of storms and the response of ozone to water vapor injections in the stratosphere is needed.

“The most surprising aspect is that this potential impact of climate on stratospheric ozone was not anticipated,” stated Stephen O. Andersen, Director of Research at IGSD. “This new research brings back into play the ‘precautionary principal’ of global environmental protection that justifies action before the science is resolved if delay would make solutions too expensive or too late to protect the Earth for future generations.

Oh there we go, global warming failed to get the sheeple to buy into the left's globalist collectivist agenda so you rebranded it climate change and that failed as well so now the sickle and hammer gang is going to trot out the 'ozone layer' boogeyman in hopes that more sheeple will agree to oppressive taxes, loss of personal freedoms and liberty and an unlimited government. What a pile of dog squeeze!!

If majority of the country’s (US) leaders are scientists, taking fast action is something that can be done. But since majority of our leaders are politicians, we can expect slow or no action at all. The US alone has another couple centuries of coal supply. So there is not a lot of pressure to look for alternative energy source. In the meantime, our greenhouse gas production continues to choke the atmosphere and climate change becomes more and more of a real threat. If nobody takes a bold and sweeping action at the present time, our children will very likely find themselves way beyond the tipping point ( )
