Chinese scientists say they have found an ozone “valley” over Tibet, an indication that the Arctic and the Antarctic may not be the only areas where the ozone layer has thinned.
Meteorologists found a significant thinning in the ozone over the Tibet-Qinghai region during summer months, according to a report Wednesday in the official newspaper China Daily.
Scientists say air pollution contributes to a thinning in the ozone layer, which protects the earth from harmful radiation, over the Arctic and the Antarctic.
According to the report, the ozone content of the atmosphere over the Tibet is about 11 percent lower than that of other areas with the same latitude from June to September. The ozone content is only 3 percent lower during the rest of the year.
