At the end of an ice age, climate changes across the globe, but this response is not uniform. In some parts of the world, oceanic and atmospheric temperatures started to rise well before continental ice sheets began to melt. In his Perspective, Lea highlights the report by Herbert et al., who show that ocean temperatures in the California Current led ice volume change by 10,000 to 15,000 years. The data support earlier results from a terrestrial record at Devils Hole, helping to reconcile them with the leading theory of ice age cycles.
