Repairing the ozone hole didn’t just help reduce the risk of skin cancer; it also reversed unwelcome effects of the climate crisis. Every summer heavy rains bubble up along the southern edge of the Tibetan plateau, but during the 1980s and 1990s the amount of rain increased significantly, raising the risk of flooding and landslides in Nepal and northern India.
Thankfully, since the mid-1990s the trend has reversed. A study shows that the increase and subsequent decrease in Tibetan summer rainfall were linked to changes in ozone levels in the upper atmosphere.
