Scientists Torn Over Repaired Ozone’s Global Warming Impact
Friday, 5 February 2010
A new report released by scientists states that the hole in the atmosphere’s ozone layer is slowly mending. While that news may sound encouraging, some scientists warn that the repairing hole may ironically further contribute to global warming. According to research, the hole led to the formation of moist, radiant clouds that are shielding the Antarctic from carbon emission temperature increases. But, as co-author of the report, Ken Carslow, warns “the recovery of the hole will reverse that,” and essentially accelerate warming in the Southern Hemisphere. The report was based off of a new, University of Leeds study using recorded meteorological data spanning the course of two decades. The study showed that the hole generated high-speed winds that caused sea salt to be swept into the atmosphere leading to the production of the moist, reflective clouds. However, some scientists think that the wind speeds were not generated by the ozone layer’s hole, but caused by emissions of greenhouse gases. Even as the ozone layer continues to recover, greenhouse gas emissions are expected to expand causing a rise in temperatures. The temperature rise would cause wind speeds to increase over time and have the same cloud-forming effect the ozone hole has now.
