Early this spring, scientists discovered a massive hole in the ozone layer over the North Pole. The largest ever detected in history, the hole covered an area three times the size of Greenland! After being open for nearly a month, the hole slammed shut. Now people across the globe are speculating why this happened and what implications it has for the future.
Did the global Coronavirus lockdown play a role in healing the ozone?
Will this change temperatures this summer?
Will the ozone hole reopen?
According to climate scientist Dr. Peter L Ward, the COVID-19 lock-down did not play a part, unlike the many reports.
…says Dr. Ward, Chief Scientist at Science Is Never Settled Inc. A 27-year veteran of the U.S. Geological Survey, Dr. Ward has been studying the relationship between ozone levels and global temperatures for more than a decade.
The relationship between ozone depletion and increasing temperature is complicated by the observation that ozone accumulates in polar regions during winter. It is during this yearly peak in ozone that depletion is observed to occur and that confuses the apparent correlation of increasing temperature with increasing ozone.
Volcanoes also deplete ozone when they emit large amounts of chlorine into the atmosphere. Throughout Earth history, whenever we find evidence of volcanoes with large basaltic lava flows, we find evidence of major global warming and widespread mass extinctions. The net effect of the eruption of Bárðarbunga in Iceland and the lower Puna eruption in Hawaii is most likely the explanation for the severe ozone depletion and warming observed since December 2019.
…says Dr. Ward. We still have much to learn about the precise chemical paths causing ozone depletion, how they vary by season, and why these effects are usually greatest during the second winter after an eruption.
Ward is sharing insight and science behind the recent ozone phenomenon and what it means for the future of global warming.
