Climate Velocity

The speed at which isolines of a specified climate variable travel across landscapes or seascapes due to changing climate. For example, climate velocity for temperature is the speed at which isotherms move due to changing climate (km yr–1) and is calculated as the temporal change in temperature (°C yr–1) divided by the current spatial gradient in temperature (°C km–1). It can be calculated using additional climate variables such as precipitation or can be based on the climatic niche of organisms.
