Finnish researchers analyzing cloud formations say ozone destruction in the Earth's stratosphere might be occurring at a faster pace than thought.
Anatoli Bogdan and colleagues at the University of Helsinki say they reached that conclusion after studying low-temperature thin and subvisible cirrus, or SVC.
SVCs cover about one-third of the planet and affect global temperatures by reflecting sunlight back into space and preventing terrestrial heat from escaping into space. In addition, the scientists say ice particles in SVCs have a drying or dehydrating effect on the upper troposphere.[...]
