Snowflake Chemistry Could Give Clues About Ozone Depletion

This article explained how snowflakes can show us the state of the ozone layer. All of snow crystals freeze differently depending on the temperature they are frozen at. However, all of them have a thin layer of water around the crystal. This layer of water causes the crystal to expand and contract depending on the temperature of the place where it is formed. The scientist Travis Knepp discovered that the hotter the area is the faster the snowflakes expand from top to bottom. And he analyzed snow flakes and saw that the flakes that are falling are becoming increasingly taller.

This article interested me because it showed that even something as cold as snow can be proof that the world is heating up. Although this does not prove anything new it is another proof of the way we are killing our environment.
