I thought the ozone hole was supposed to be shrinking?

One possible reason for the higher-than-normal growth is the Hunga Tonga volcanic eruption in January 2022, which introduced massive quantities of water vapor into the air. “The water vapor could have led to the heightened formation of polar stratospheric clouds, where chlorofluorocarbons (CFCs) can react and accelerate ozone depletion," said Inness.

Yet despite experiencing large seasonal growth this year, the ozone hole is still decreasing in size overall. "Based on the Montreal Protocol and the decrease of anthropogenic ozone-depleting substances, scientists currently predict that the global ozone layer will reach its normal state again by around 2050,"

I learned about the Tonga eruption recently and it is wild.

What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...
