Cold is a physical sensation and condition characterized by low temperatures, commonly associated with ice and frozen objects like icebergs. The concept of cold matters because it affects how people and divers communicate and respond to environmental conditions, as shown by its use as an informal safety signal in diving practices.

A part of the notoriously cold Polar Plateau, it is representative of the majority of the continent's surface.]] Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale.
