    Arctic ozone reaches record high in positive step for climate

    Modeling representation of Arctic ozone hole recovery in 2024. Credit: Michala Garrison, NASA Earth Observatory. The Earth’s ozone hole in polar regions, where stratospheric ozone levels have been significantly reduced, has been featured frequently in climate change news in recent decades. Anthropogenic chlorofluorocarbons (CFCs) are the main culprit and are emitted by household products such as refrigerators, air conditioners, and…
