High specific heat is important to life on Earth. A large body of water can absorb and store large amounts of heat from the sun in the daytime and summer while warming up only a few degrees. At night and during winter, the gradually cooling water will warm the air. High specific heat of water also stablizes ocean temperatures and creates a favorable environment for marine life.
