EYE-suh-thurmz

Definition

Lines on a map connecting points that have the same temperature at a given time or during a specific period.

Etymology

Derived from the Greek words 'isos' (equal) and 'therme' (heat), the term was coined in the 19th century by Alexander von Humboldt to help map atmospheric temperature patterns.

In the news

The article mentions that climate warming elevates zero-degree isotherms, meaning the altitude at which freezing temperatures occur is rising, which contributes to the melting of the ice that holds glaciers to the mountainside.
