Science has shown us that since Earth’s creation, climate has been affected by natural occurrences,both within and outside the climate system, but in recent years, climate is also being affected by actions andinactions of the human race. Climate system changes affect all life on earth, but fisheries are affected inparticular, because almost three-quarters of the Earth’s surface is water and home to a variety of aquatic life.Changing weather is producing more droughts, floods, rising sea levels, salt water intrusion of fresh water,acidity in the oceans and ocean warming. This paper discusses how climate change is affecting both marinelife in the oceans and aquatic species in fresh water, as well as the effects of these changes on the seafoodsupply chain and other revenue sources in coastal areas. Factors causing climate change and actions needed tomitigate these changes are also discussed.
