Definitions:

Climate Change

Substantial changes in global or regional climate patterns, notably since the late 20th century, largely attributed to increased levels of atmospheric carbon dioxide produced by fossil fuels.

End-Permian Extinction

The largest mass extinction event in Earth's history, occurring around 252 million years ago and resulting in the extinction of a significant proportion of marine and terrestrial species.

UV-B Radiation

A portion of the ultraviolet spectrum with wavelengths from 280 to 315 nanometers, known for its biological effects, including DNA damage and vitamin D synthesis in skin.

Acid Rain

Precipitation with a pH lower than normal, resulting from atmospheric pollution that causes environmental harm.
