Suppose a recent study conducted by scientists at NASA suggests that the Earth's ozone layer is showing signs of recovery, thanks to international agreements to reduce the use of ozone-depleting chemicals. The study, based on satellite data collected over the past decade, shows a significant decrease in ozone depletion over the Antarctic region. Scientists say this is a positive indication that global efforts to protect the ozone layer are working.
Can we infer that "The ozone layer is fully recovered and no longer at risk."? Yes, no, or maybe?
