Mounting scientific evidence is showing how Earth’s largest organisms can join forces with some of the smallest to combat climate change. This unlikely pairing is between some of the largest and tiniest life in the ocean, whales and phytoplankton. They work together through a process called the whale pump. The end result? Removal of carbon dioxide from the atmosphere which helps to mitigate climate change. Recognition of this value and other important ecological values that whales naturally support are gaining global attention at venues such as the International Whaling Commission (IWC) biennial meeting which begins next week.
